Games that use mc2_s1.irx, specifically those that contain the string "PsIImc2_s1 3100", may very well corrupt any memory card that is in the same slot as a VMC. The version that comes with Mana Khemia and other Gust games directly accesses the SIO2 device rather then going through sio2man like they are supposed to. The mc2_s1.irx in Star Ocean 3 is okay as it's version 3.20 and contains "PsIImc2_s1 3010".
hmm i guess i'll have to go through my games one by one.
can you share more info on more specific titles, aside from mana khemia (1 or 2, both?) ?
Those in the compatibility thread that say they corrupt memory cards are affected. Only thelast ps2 games made should have that version. Don't bother checking older games.Quote:

I am myself one of those who has switched almost entirely over to using VMC via your OPL branch for my gameplay, so I definitely have a vested interest in helping to make this work for all games if possible. For the time being I'm just holding back from playing affected games... But I have plenty of MCs, so I am willing to participate in tests even if some of them may result in total MC corruption. With backup MCs it's no problem to recover from such events anyway.

I am willing to test too to improve VMC compatibly I have no problem reinstalling FMCB and have like 6 MC so no problem here either love VMC no need to switch MC to find game saves :)
I think a have a partial solution for this. It won't save properly yet but it shouldn't corrupt real memory cards or hang and the it shouldn't break anything else. Test it, if you can, with real memory cards that you don't need the contents of just in case.
SLUS_218.90.Mana Khemia 2: Fall of Alchemy
SLUS_214.45.Antonlico Melody
Tested SMB mode to first save point with active VMC do's not save just as stated but do's not corrupt MC anymore.
Nice work hope you can find a way to allow VMC save but nice anyway :)
Working on Real MC save will update takes time for intros long.
Back with update pass threw working with both games real saves save and load fine
More progress, reading works. I had to modify a bunch of things so test other games to make sure they aren't broken.
Tried multiple games seams they are ok did load and save then reload
did notice loading now when creating VMC with mca_v20.elf but saving to it seamed to corrupt the VMC but no problems with real MC to no problems just to get it to wright next one step closer nice work :wow:
It should be working now. Again, test with memory cards whose contents are expendable. There are some parts which are specific to the build of mc2_s1 that comes with Mana Khemia, hopefully most games that are affected use the same build.
