PS3 Mednafen Latest Revision Thread!

[The Central Scrutinizer]

Mednafen for the PS3 has been getting updated so frequently lately that it's made it almost impossible to keep up with. With a new revision coming out every few hours or so, Mednafen is well on it's way to becoming another great edition to our ever growing library of underground apps, games and homebrew for the PS3 entertainment system. In less then a week, Mednafen has gotten all the way up to revision 30!

A quote from Robo Hobo:

Project is under heavy development, there may be bugs, please report issues so they can be fixed!

Supports NES, GB, GBC, GBA, SMS, GG, PCE. Zip files. Save States.

Will support PCE CD, Atari Lynx, NeoGeo Pocket Color and WonderSwan in the future.

Mednafen PS3 README/Changelog

This is a port of the Mednafen Multi-System emulator to the Sony Play Station 3.
It is currently based on version 0.9.12-wip

Features:
Supports built-in NES GB GBC GBA SMS GG MD(Genesis) PCE PCE-CD NeoGeo Pocket (and color) WonderSwan (and color) emulators
Supports Nestopia(NES) Gambatte(GB GBC) and VBA-M(GBA) external emulators
Load uncompressed or zipped images
Save and load save ram and save states (not currently supported in Gambatte and VBA-M)
File browser, place your games on a USB drive, or FTP them to the internal drive
Fast forward

The first time you load a game for a system, you will be asked to configure the controls, you can reconfigure them later by pressing L3 + R3.

Future:
Better user interface
Improved Two player
Other features
Possibility of netplay
Faster and better GBA support

Use:
PCE CD support requires bios at /dev_hdd0/game/MDFN90001/USRDIR/pcebios.bin and currently only supports bin + cue, with all tracks inside the bin (no external audio tracks yet, sorry)

File Menu
Up and Down to Scroll the list by 1
Left and Right to scroll the list by a page
R2: Toggle Bookmark
R3: Open emulator select menu
Cross: Select File or directory
Circle: Go to previous directory
Triangle: Exit

In Game:
R2 for fast forward
R3 to open settings menu
Hold L3 + L2 to save state
Hold L3 + R2 to load state
Hold L3 + R3 to redefine controls

Settings Menu:
Up and down to choose setting
Left and right to change the current settings value
Circle to exit menu

Bugs and Issues:
Loading new games does not work, it will drop you back to the XMB
VirtualBoy support hangs PS3
Lynx support is currently disabled
Gameboy Advance support is spotty, some games can't get to full speed
Some features may be missing from WonderSwan and neo-geo pocket
VBA-M is currently not available for Gameboy mono and color emulation
SNES support is not enabled or tested for that matter

Notes:
I get the feeling that the new mednafen-wip drivers don't support big-endian processors yet, megadrive needed modifications, VirtualBoy doesn't work, and pce_fast has all background tiles flipped on the x axis.

Thanks to:
The original author of Mednafen, and all of the emulators it contains.
The authors of Nestopia, Gambatte, VirtualBoyAdvance (and all of it's forks)
The people who make the PS3 jailbreak possible

The following is a list of changes since it's inception;

Changes since Oct 25 2010

R2 - [No log message]
R3 - A few too many files.
R4 - Hopefully fixes loading non-zipped files.

Update from Robo Hobo 11/03/10 - Broken compiling on SDK 1.92

No time to test save states right now, but for normal saves you may need to uncompress it. It's stored as a gzip file. On windows if you have 7zip installed, just right click on it and select extract here to get the file. I'll try and sort saves out tomorrow, maybe even add mednafen's cheat function if I get the time.

At any rate, I seem to have broken compiling on SDK 1.92, but for those with firmware 3.41 here is mednafen-wip r59, with Megadrive support. Please read the readme and note that some features are broken (loading new games in particular), but this will install separate from the old version in case you really miss them.

Thanks for the update!

To keep avoiding having to disconnect my USB stick back and forth on my PC and SP3, I FTP the package file to my USB stick on my PS3 and then just do the install through the PS3--I think I'm getting lazy having to walk over to the PS3 console and disconnecting it and so forth. lol

Heh heh, cool. I do the same thing too.

Thanks for the update!

You're welcome.

The bug with switching "loading new games" and using the "bookmarks" feature is still an issue with this version--seems the bug creeped up after R23. I find it easier now to unzip all my ROMs, since they seem to load without an error (getting sent back to the PS3's XMB menu), but it's still not 100% perfect, I do occasionally get the error.

[pikafunk]

this is a very good effort!

it would be perfect if it supports genesis

[Jay-Jay]

R23 - PCE CD support, ftp bios to /dev_hdd0/game/MDFN90000/USRDIR/pcebios.bin, use only BIN/CUE with no external tracks or PS3 may hang.

Anyone know where we can get this PCE BIOS?

Asking for roms is probably a no-no here. The standard response would be to dump it from your original game/console.

Plus it's just lazy when googling takes you straight to the prize

[keropi666]

Anyone know where we can get this PCE BIOS?

I think all you need to do is rename SYSCARD3.PCE to pcebios.bin .... SYSCARD3.PCE is the "cdrom² system card v3" that the original pce needed to boot from cdrom

Thank you. That's exactly where I was stuck at and you just gave me the solution. Thanks again!

[315Groove]

Do you actually have cdrom working? I have tried MANY things to get my copy of Dracula X Rondo to play. I have tried with wav versions, with mp3 versions, I have tried renaming the cdrom syscards and putting them in USRDiR. I have checked my cue files to make sure they are correct. I have also been trying Super Raiden to make sure it isn't just the game, but they both just kick me to the XMB over and over. Some of my card game roms work. I'm at a loss, if anyone has it working can you post details of what kind of files are on your disc, what you used for the pcebios.bin, did you have to rename the cdrom syscard, where did you put the file. Are you just running the files of an HDD, if so, internal or external, etc. I'm stumped, and I have tried so many different things.
