Hey, I've uploaded here PS2InfoGB rev 6a. It's USB Mass Support version.

All changes in my revisions:

=> Rev.6a
- Added: Access to mc1:/ device
- Added: Support for sub-directories
- Added: Sorting list (separately for folders and files)
- Added: Possibility to change buttons configuration
- Added: New In-browser menu with options (push start in browser)
- Added: Load and Save Game State (beta)
- Improved: CPU core (minor changes)
- Improved: Real Time Clock
- Improved: Preselected ROM option
- Changed: GUI - the way of selecting devices, some warning boxes etc.
- Removed: File gb.brm (what that file was for?)
And a lot of changes invisible for users
------------------------------------------------------------------
=> Rev.5c
- Fixed bug: program stop on white-screen when folder PS2GB already
exists, but the file gb.brm dosen't exist in the same time (hopefully)
- Improved: MBC3 controller - should resolve problem with battery-backed save game
- Added: USB Mass Storage Support
- Added: Real Time Clock support for MBC3 controller
- Added: ability to back to browser when ROM can't be loaded
- Added: ability to run cardridge type:
* 'ROM+MBC3+TIMER+RAM+BATTERY'
* 'ROM+MBC3+TIMER+BATTERY'
* 'Hudson-HuC3'

More details in ReadMe!.txt, please read this file.

One important message you have to read:

In revision 5c I've made mistake :cry: Now it's fixed, but SOME SAVE GAMES, WHICH USE REAL TIME CLOCK (ROM type ROM+MBC3+TIMER+RAM+BATT and ROM+MBC3+TIMER+BATT) MIGHT BE NOT COMPATIBLE WITH THIS REVISION (IT'S ACTUALLY RANDOM). THE ONLY WAY TO FULLY FIX IT YOU HAVE TO REMOVE OLD SAVE AND START GAME AGAIN.

Well, probably you will be able to continue game but without real time clock. Sometimes games offer to set real time clock (e.g. Pokemon Crystal), but you will set it every time you load battery backed save.

Enjoy!

PS. Happy New Year 2010 :)

it did save and time worked with my pokemon crystal rom

Timer works, but Real Time Clock doesn't work. So, the real time will be constant in your game.

if possible gbc added to it too? thanks for the update though will use it

But gbc is already added. If there is a ROM which dosen't work, please leave title of this game here, I'll try to find out what is wrong.

BTW I have finally implemented version with RTC (not uploaded yet). It works fine but, there is some problem on PS2. When I save game state and run again ROM it's ok, but when I reset the PS2 and I'll load ROM again, the time is restarted :( (I tests it on Pokemon Gold). Then it's necessary to set time again in game.

I compiled the same version for Win32 and here it works fine and problem doesn't occur.

The only one difference is I used libps2time to get UNIX time on PS2, because standard time(); function dosen't work (it returns -1 value).
The save game looks fine, every necessary information are contained in it. So I have no idea why it doesn't work.

No, it dosen't work. This ype of ROM - HuC3 - is not implemented (and HuC1 as well). I think it can be my next goal ^^. But there is a little problem. This type of ROM is not documented well. I will see what can be done :)

phoenixclaws

03-31-2009, 04:38 PM

Thanks for looking into it KarasQ.
I know HuC3 and HuC1 is implemented in BGB (http://bgb.bircd.org/) and KiGB (http://kigb.emuunlim.com).
Maybe some contacting with emulation authors might help?

Also, there is documentation about the headers of various carts at fms.komkon.org (http://fms.komkon.org/EMUL8/).
Not sure how much help the EMULib documentation is but it might help.

I also found this (http://necrofamicon.com/Retromancer/PyVBA/src/gb/gbMemory.cpp) from the VBA emulator which has some coding specifics.

hey is there a way to add ir links? like use gbc and ps2's ir sensor on games that need it?
just tried this out very good! oracle of ages/seasons runs i'm happy but sound might need to be tweaked:}

KarasQ

04-07-2009, 02:10 PM

OK. I finally resolved problem with RTC, so I uploaded new revision (PS2InfoGB rev 5c)

changes only for rev5c

- Added: Real Time Clock support for MBC3 controller
- Added: ability to back to browser when ROM can't be loaded
- Added: ability to run cardridge type:
* 'ROM+MBC3+TIMER+BATTERY'
* 'Hudson-HuC3'

@phoenixclaws - I added HuC3 support, HuC1 not yet, because I can't find any ROM with this type.

@zin0099 - I don't thnik I could to add ir links. I don't know much about that, but yeah sound definitely need some improvements ;)

Just have to say it....thanks again. Also a side note, this also works on the PS3(20, 60gb) with psxloader. Your revision is the first of the gameboy emulators I got to work on the PS3:D

ItÂ´s also confirmed working on a PAL 60gb ps3, which mean it also works on the old 80gb NTSC ps3 with ps2 BC. I had been trying to compile an older version of this emu just with the intent of trying to get it running on the ps3.
YouÂ´re making it better and at the same time itÂ´s now ps2/ps3 compatible.:)
Nice work!

Were the older versions using the ps2Â´s internal time clock? IÂ´m just curious as to what changed that made it finally start working on the ps3.
Anyway, thanks for your work on this. one more emu on the working list for the ps3.

Hopefully at some point in the future the sound core will get overhauled. The current sound emulation is painful. I guess that's why it is set to off by default. *chuckles*

~Phoenix~

EDIT: I can only think of one game that actually used the HuC-1 chip and that was the Japanese version of the first Pokemon Trading Card game. It's commonly known as PokÃ©mon Card GB (J). (Source: Dorando (http://dorando.emuverse.com/html/pokemon-card-gb.html).) The North American and Europe versions were moved to the MBC5 chip. I'm not sure if it is absolutely necessary to emulate the Huc-1 but thanks for working on InfoGB ^_^.

Edit #2:
Bug Report: Pokemon Crystal Version (U)
1. Some really strange graphic bugs that look like "s and numbers pop up at the top of the screen every time dialog is initiated.

2. Also during every pokemon battle there is a part of the opposing pokemon that appears above it during its static state (in other words not during animation). Plus there are some odd bug with the border that the actions are chosen from. I think the health bar has a graphics bug on the left end also.

3. Finally, while accessing the computer in the pokemon center. Access Bill's PC and then choose to withdraw a pokemon but then cancel (X) and then you get a "black" screen. Hit cancel again (X) and it refreshes the screen.

Thought you should know this and so far I have only gone a little bit into the game.
Plus this game only recently became playable due to your changes :).
It is very playable even with these little bugs.

Yes, I knew about these graphic bugs, It seems to the only Crystal version has them, Silver and Gold works better, actually I haven't noticed any bugs in these both versions yet, but I don't play much, so thanks for bugs report anyway :)

If I get some free time I'll try to debug this emu a bit.

IÂ´m just curious as to what changed that made it finally start working on the ps3.

Hmmm I added some initializing functions, because the USBD.IRX and USBHDFSD.IRX couldn't be loaded before. Maybe it made this ELF bootable?

Hi there, new to the forum, Nice work on this emulator for PS2, i been playing around with just black and white game boy at the moment, and works great, game play and sounds not perfect yet, but still works really great!

Does this emulator support gameboy color and gameboy advanced?

A few suggestions i would like
1) like SNES Station and PGen, i would like this emulator to support Sub Directories such as this Rom/A Rom/B and etc, basically i would like to beable to order my rom by alphabetical order in a Rom folder without making a big mess out of the root directory.

2) Controls i really do not like, i think the start and select button should be in there right place instead of triangle as that and the menu button i think should be moved to either R1 or L1 and X and O for actions on the game boy games.. other buttons maybe R2 and L2 for load and save states?

3) Option for centering screen.. if i am not missing it..
4) instead of always pushing start to return to a page, how about just clicking triangle to return to the page.. similar to the other emulators?

Hope i ain't sounding to picky, but this is so far what i think would be nice.

Emu supprot gameboy and gameboy color only.

1,2,4. I'm planing to improved a bit browser and add these functions, but I'm afraid that I have to probably rewrite huge piece of code ;)
3. It's already implemented, valid only in submenu: PS2_SELECT+PS2_DPAD for screen centering

BTW load and save state options in submenu doesn't work. Save game is only possible when you save your state directly in game and then you choose "Back to the main menu" option. It'll save your data game to *.sav file on mc0:/PS2GB/

Note that this was an emulator started by someone else and then picked up by dlanor for a very short period to add somethings.
Now KarasQ has very generously picked it up.
I believe he knows what he's doing and i'm grateful for the additional mappers and other fixes he has coded in ;).

This is great work KarasQ - the USB option works a treat (Slim PS2 FMCB 1.8). I have one request though - is it possible to force original Gameboy roms from black and white to color? Or an option to have original gameboy roms in their original monochrome or GBC color? Its not an issue much though - this emulator is greats. Thanks again.

Hey KarasQ

I was just playing with Pokemon Silver and some similar bugs show up that I saw in Crystal.
The "blackout bug" when you back out from accessing the Withdraw or Deposit or any other window in Bill's PC is there.

Also a different bug showed up for me on silver.
I have a bunch of Pokemon now in my possession and when i go to switch them a weird bunch of black covers over some of the pokemon. It goes away after I switch.

Also some black shows up when the opponent pokemon attacks in the battle window. The sliding movement uncovers some black area when it should still be white.

I'm not sure why this is but it is very apparent and a little annoying ;P.

Thought you should know I have been testing your revisions and overall it is a wonderful update. Keep at it and thanks. :)

EDIT:

I was just playing this pokemon/robopon like game called Metal Walker on an emulator and it seems like a fun game.
So I tried it out on the PS2InfoGB emulator and it gets through product and copyright screens fine but none of the intro or in-game seems to work.
It's completely black except for when you press the (O) button you'll get the name entry screen and you'll seem some screen transfer flashes but not text for the story. After that it is black and unplayable. It uses the MBC5 chip.

Hmmm... the most funny thing is that the game works properly on the same version of emu compiled for Windows... (?) so the MBC5 works fine. I have tried with other graphic library on PS2 and it's the same result, so the problem seems to be in other part of code maybe infogb_plot_line() function... but other games work fine... it doesn't make sense for me.

Anyway thanks for your post, I'll do some tests soon. Right now I'm a bit busy (I have to pass some exams etc in my school first)

Yeah I have exams myself. I really am grateful that you're working on this emulator. It is nice to play stuff that I just don't have the hardware for. :)

I noticed when i accidentally typed a "," in a few rom's names that they don't show up in the rom list. Not that anyone really has a reason to actually put a "," in there, just found it interesting... Also, do the Pokemon GBC roms(Crystal, Gold, & Silver) run unbearably slow? It takes forever to walk and I can't even get past the where it asks if it's Daylight Savings Time because it locks up(sometimes freezes at the Day select part too). I don't know if it's just me having that problem or what, but i'm running a v.9 PS2 with FMCB, been running from uLaunchelf though. dunno if that helps. keep up the awesome work KarasQ!

ok this reply is really late but... I figured out what my problem was. Apparently my USB stick reads extremely slow or something, because everything worked fine from a cd. I think it's my USB stick because snes9x and snes-station do the same thing from my USB stick. Just thought i'd post this in case anyone else had the same issue...

Also @KarasQ - If you are still working on this project, do you plan on implementing HDD support eventually, if not that's ok, I was just wondering(it's my preferred way of loading, but I know USB is more popular)?

KarasQ

11-02-2009, 04:43 PM

In summer, I wanted to stop working on this emu and make Visual Boy Advance port to make finally GBA for PS2 and better GBC emulation. I even succesfully did this, but when I realized that to run any GBA ROM it require 32 MB (:wow:) then I left it. Now I know why there is no GBA emulator for PS2 (The only way to resolve it is to make memory paging, I think gPSP has something like that, but it's too many work to do this for VBA).

Recently I was a little bit absent, but a week ago I've starded working on browser for PS2InfoGB. I decided to improve it - to add sub-directories support, sorting list (separately for dirs and files), to separate device entries from dirs and files list.
Not much changes but a bit of code to rewrite. I have actually done :)

Currently it looks like this:
http://www.kry1.user.icpnet.pl/inne/infogb_rev6.gif
(The text at the top is for debug so it will disappear ;))

I have to test it a little bit and do some other stuff yet, but if I successfully done everything I will post a new revision.

@SoulSlayer
I would like to implement HDD support, but since I have only PSTwo Slim I can't do it myself. I'm going to release source code so maybe we find somebody who will do it or can help me do it. All I need is just a function which return number of entries from specified path and save entries from hdd to array or just list it on the screen.

A better sound-emulation + SGB-Border-Support would be cool. ^^
The User-Interface where you choose the device looks nice.

Great to see you back KarasQ. Too bad about the GBA emulation maybe somebody could pick up your sourcecode and take a crack at it another time.

I like the new slick GUI for PS2InfoGB and I hope you can get the sound emulation improved a lot too :).

EDIT: Btw, I'm amused to see the Robopon and Metalwalker games that I mentioned about months ago in the screenshot :p.

I really apreciate the efforts KarasQ is putting on this emulator. :)

I was wondering why it never had a "browse sub directories" feature.
Now it's solved.

I'd like to ask if it's possible to change/implement some code to get better sound emulation, since some sounds aren't played by this emulator (like the "pikachu's voice" in pokemon yellow/pinball).

Thanks and congratulations!

The Dreamcast has 3 or 4 GBA emulators.
None of them at full speed (very slow, I'd say) but very compatible.

Since this console just have 16MB of main ram, what they did? Some kind of magic? :wow:

About gbc emulator, is there any possibilty to make it save the sram while the games are running?

'Cause I always forget to stop emulation before turn off the console and lose my saves... :p

hi, thanks for you great work. I got problems saving in gb roms like final fantasy adventure an legend, the savefiles are created (I´ve browsed with ULE) but they doesn´t load. Other games like pokemon save without a problem.

I´m using a FMCB 1.8, ULE 4.40, InfoGB rev5c
I'm not sure, but I think your problem may be due to the length of the filenames of the ROM files. The emulator tries to base the gamesave names on the names of the ROM files, but may be doing this with improper truncation, especially if the ROM files are stored on a filesystem allowing larger name length than the PS2 MC filesystem does.

Try to ensure that the ROM names do not reach the MC maximum of 32 characters, including the extension and its separator. (Here even the "." character counts as part of the name.) Do not worry about the folder names though nor about the separating slashes, as these do not count into the name length limit of a file on MC.

However, if you have a ROM file named "12345678901234567890123456789.GB" which is exactly 32 characters long, this still counts as being one character too long, as the emulator wants to replace the ".GB" part with ".sav", which is one character longer...

If your ROM collection is anything like most others I have seen, intended for use with emulators on PC systems, then you may very well have to rename the majority of your ROM files, in order to reach a full name length of 32 characters or less for all of them.

Best regards: dlanor

I already rename all the roms, the final fantasy roms have around 25 characters. I've tried diferents roms and names like ffa.gb but even it doesn't load the saves. The gbc roms doesn´t have these problems
The emulator is runing from my MC and the roms are in a folder in a pen drive

I thought InfoGB was a port from the InfoGB from Windows and not VBA-M.

SoulSlayer

12-29-2009, 08:16 PM

Oh man, I got confused(I should never read multiple threads at once...). Anyway, yeah, InfoGB has absolutely nothing to do with VBA-M as far as I know, and I'm sorry about the confusion, but vba-m does have this problem as well... as does InfoGB 05J, though I don't know what version of InfoGB the ps2 port is derived from or even if there are multiple versions of the pc emulator.

Yes I finally got some time to finish browser for this emu so now I will try to improve emulation.

The Dreamcast has 3 or 4 GBA emulators.
None of them at full speed (very slow, I'd say) but very compatible.

Since this console just have 16MB of main ram, what they did? Some kind of magic? :wow:

Two weeks ago, I did port of deamcast port of GBA emulator (lol) - gpSP 0.8 for PS2 and it's loading ROM but it's not playable (about 0.5 FPS). Actually I'm disappointed, I expected some more FPS. Dreamcast isn't faster than PS2, is it? Something else must slowing it down, but I haven't found what yet.

About gbc emulator, is there any possibilty to make it save the sram while the games are running?

'Cause I always forget to stop emulation before turn off the console and lose my saves... :p

Done, but need some tests.

Ok I will try find out why is that. For now you can try new feature (Save Game State and Load Game State)

EDIT: Btw, I'm amused to see the Robopon and Metalwalker games that I mentioned about months ago in the screenshot :p.

Yeah :p, anyway Metalwalker still doesn't work. I will try reimplement graphic emulation and maybe then it will works.

Graphic and Sound emulation are quite big issues for me (especially Sound). Honestly I've even started reimplementation of sound but I'm not really sure how to finish it :P I'm stuck. This emu is written in other way than it will be, and it's even quite hard adapt other sources of sound emulation to this emu. On the internet there is lack of informations about sound emulation. But I will keep trying.
