unofficial LaunchELF v4.42

will write support require a new "client" for the pc?

That's great to hear that you fixed it.

Yeah, I was quite worried there for a while. I really should have caught on sooner though, but I was fooled by the fact that this really was an old bug, and I expected it to be something in the new code sections. So I was looking in the wrong places at first.

That's odd because with FTP it only takes 6 minutes to transfer a 313MB file PS2 -> PC at an average of 875+ KB/s here.

I've heard the same from others, but never seen it myself. Here 4KB/s is the top speed in that direction, though I get normal rates in the other direction.

Note that this problem only applies to the PS2 though. I have no problems FTP'ing stuff to the PC from Internet sites.

I get really good uploads over the FTP with my PS2..... Not sure the speed... but a lot better than 4KB/sec....

I know, same as others report too, but not me.
I've never had a decent FTP transfer speed from the PS2 to the PC.

I know this sounds stupid... but have you DMZed your PS2 (if using a router)?

I use two network cards in the PC, and one of them is dedicated to a subnet which includes the PS2 (and usually nothing else). I also have some old Atari computers connected to the same hub, but they're always OFF nowdays, so network-wise they don't 'exist'. The only thing between the PC and the PS2 is a simple hub, and there is no software firewall.

Of course I use Flash FXP over a Linksys router...

I use a Netgear RT314 router for Internet access, but this is connected only to my PCs and the ADSL modem, not to the PS2 which is on a separate subnet, both physically and IP-wise. And my FTP client is FlashFXP v3.3.4, so that shouldn't be a problem either.

this may vary with different FTPs, firewalls, and networks setups.... although I'd think that the Host system would come under the same symptoms........

Precisely, but I have no problems with that, or so I think anyway...

Who knows ?
Maybe the 300+ KByte/s I get in HOST writes to PC is really a lot less than others will get, though I doubt that the same factors can apply as for FTP.
(So high rates would be impossible.)

Yes. The old ps2client versions lack several of the functions needed. You will be able to write files, only, when using those versions. Anything more advanced will simply cause them to abort, so you need a new version for those functions, which include:

Creating new folders (directly or as implied by pasting)
Deleting files
Deleting folders

Those 3 functions will require a new server, and if I also implement renaming (not decided yet), then it will have to be a server designed by me, as the standard ps2client sources contain no support for that.

In fact you'd need my server version anyway, to use the present test version of the new HOST code, because I added the IOMAN bug-fix into ps2client. But I have reconsidered that choice and will move that bug-fix into the PS2HOST IRX module, where it belongs.

I have implemented those functions in RadHostClient so it shouldn't need updating.

Great. Then all should work except 'Rename'.

I still haven't decided how to do renaming, but I'm leaning towards implementing an 'ioctl' call for it. It's the only function spec within the standard that is intended for adding new features, and it has sufficient freedom in arguments.

So what we do (inside LaunchELF code) is to start with fioOpen (for a file) or fioDopen (for a folder), to choose the object to rename. Then we use fioIoctl with a request code (arbitrarily invented ?!? ) for 'Rename', and a pointer to the new name in the data pointer argument. Finally we use fioClose or fioDclose to free the filedescriptor used.

All that needs to be added to implement this in a client program is the new ioctl function, since the rest is fine as-is.

The same technique can be used to implement renaming for 'mass:' too, but not for MC (since we rely on the ROM IRX for that).

If you guys ever get this one figured out, let me know because ATM the best I can d/l through FTP from my XBox is 4-5k/s which is just plain wrong. Im guessing its something to do with sync/async trying to talk to eachother, as it hasnt always done this to my xbox and no software changed in between (but of course, I have no idea how to check if the PC/Router/Xbox/PS2 is running in sync or async mode in an easy manner).

On a lighter side, I get much better speeds when transferring through uL's FTP off my MC to PC. Thanks for adding all this great stuff to LaunchElf, it is impressive what has been done to this app (not to mention what you are working on ATM with HOST and such)

I agree, your MC backup utilities should not be forgotten just because they finally get some decent competition. And as I see it this scene is not really about competition, but rather about 'contribution'. So just like you contributed info and tips to us earlier, please feel free to grab any methods or code snippets you may find useful from our sources.

Thanks, but I've pretty much been done with ps2 coding for quite a while. I got extremely pissed off at it when some simple bit of code I was trying to do should have worked but kept exceptioning. And never being able to get graphics to work right even when they should've drove me nuts. I was looking forward to the LaunchElf with MC backup capabilities since I use LaunchElf as my main boot up app and hate having to switch over to MCManager and restart the thing. Unfortunately, the way you're doing it seems a little overly complicated to me so I don't plan to switch. When I back up games, I'm mostly looking to free a certain amount of space from my MC, so having the size of the save listed with the title of the save file is very important to me, and seeing the timestamp when I put the cursor over the save (in case I have 2 saves of the same name, I know which is newest). Which brings me to another issue: you can't have 2 of the same saved game in the same directory. Plus, I just find it annoying to have to copy/paste, instead of a one click solution. If you'd like more in depth input from me or where I think the problems lie and how they can be fixed (with minimal work), let me know and I'll be glad to work with you on it. Not that I'm an expert or anything, but I know where MCManager's problems were and how I'd have fixed them (though I never bothered 'cause I figured it'd be better to have backup abilities in uLE).

EP: Does Wizardy work? If so, I'd certainly like to know what the problem was. And that middle finger comment was made (jokingly) to the person commenting on finally a decent backup tool. If I'd known it'd have taken you guys so long, I'd have added it to uLaunchElf myself months ago :-P I am pleased, though, to see the code has been cleaned up since the last version I looked at :-)

I don't know that's just it neither I nor dlanor have the game to test. I looked at a few X-port saves but there are quite a few different versions of that game.

Yeah I know hence the . This mc backup routine is special because it preserves special file/dir attributes, timestamps, etc. No known homebrew or purchasable software can make backups like this can. Now GTA VC knows which save to load because the timestamps are intact. It loads the newest one.

if possible, could you list what libraries and their versions you are using in your dev environment (and if possible, links to where they can be downloaded). back when i set up an environment when i started working on ps2script, the libraries i used weren't the most corrent at the time, but it was enough to do what i wanted to do. i'd like to get an environment set up so that i can help in importing ps2script onto uLaunchELF.
