PS2 isos that fit in a CD wont work on PS3HEN and PS2 Classics Launcher

[alfredox123]

After a lot of testing and converting and reading as much guides i could, i got to the conclusion that ps2 isos that can fit in a CD simply wont work. If it is above the CD size works for some reason. I always get the error 80028f17 if i launch a CD sized ps2 game, the best i could reach is if i convert that CD sized iso into a bin cue files i atleast get to the ps2 logo but then black screen.

The game is compatible with ps2 emu on ps3 as estated in PS2 Classics Emulator Compatibility List, i verified the md5 and it is the same as redump database, the game works if i used in pkg format for some reason. The game in question is capcom vs snk 2

I dont know what i could be missing, i followed the guides and nothing seems to work to use that game through ps2 launcher from here, it only happens with ps2 games that fit on a cd in iso format, if the size is more than a cd size it works through ps2 launcher.

I haven't worked with PS2 classics in ages. If I recall correctly, there is an old version of PS2 Classics GUI that doesn't create correctly the LIMG and the ISO needs to be edited with a Hex Editor

Check if the encrypted .BIN.ENC contains a proper LIMG. The last field must of LIMG must match the sector size of the ISO.

In the following example 02 ED 90 = 191,888 sectors, 09 30 = sectors size is 2352 bytes (2ED90 x 930 = 451,320,576 bytes):

L  I  M  G  ---------CD ---#SECTORS SECTOR SIZE
4C 49 4D 47 00 00 00 02 00 02 ED 90 00 00 09 30

Is there a more user/noob friendly way to do this?

[aldostools]

My suggestion is that ask in PSX-PLACE forum (or another forum with PS3HEN users).

As I mentioned earlier, I haven't worked with PS2 classics in ages because it isn't needed on CFW... I have forgotten many details.

i think im gonna stay with the pkg version and call it a day (or various testing all sorts of configs lol) thank you anyway

[alfredox123]

Tryed this again since there's a new PS3hen and seems like PS2 place holder was updated 2 weeks ago, but still can't make it work. Only works with PKG for now.

[aldostools]

PS2 Classics Launcher is only a placeholder to load .BIN.ENC.

So basically it's the same as using PKG, except that the .BIN.ENC / CONFIG are replaced each time a PS2 game is mounted.

Check your .BIN.ENC and CONFIG, probably they were not created properly.

I downloaded the config from here https://github.com/aldostools/webMAN-MOD/wiki, i uninstalled the old one and reinstalled again just in case. Of the ps2 games i have, this is the only one that doesnt work and its also the only one that is under 700mb, the iso isnt bad because i double checked with redump md5 and its the same, also i encrypted it with apollo (i updated it also) but still no avail.

I'm not sure if it's related to this issue, but you could try changing the disc type from 01 to 02 (or vice versa) in the 8th byte of the LIMG section of the ISO:

[alfredox123]

i dont understand what to do here, i have the iso and hxd, how to find the 8th byte?

[aldostools]

It's explained in the post: Search LIMG, it's next to the next of the ISO.

[aldostools]

Sorry... I mean the encrypted ISO (aka .BIN.ENC)

[aldostools]

If I recall correctly you have to decrypt the .BIN.ENC first.... I haven't done this in almost 10 years, so I barely remember the exact steps.

[alfredox123]

i did the decrypting, changed the 02 to 01 as in the isntructions, encrypt again and still nothing :c

[aldostools]

Try creating the .BIN.ENC with multiMAN or PS2 Classics GUI... maybe the issue is Apollo.

I really don't know... my PS2 CDs work fine.
