It's also another case where we give (documenting how the decryption works etc.) and then others feel they have the right to walk all over that and not give themselves in return, just try to profit from MAME. Disgusting bullshit, makes me 100% disinterested in working on the driver at all.
Sure i agree with what your saying. but although i dont give a toss for PGM2 myself there are people out there who obviously do and as such will turn to some immoral hacked build of MAME in order to get their fix.
IMHO The only way to stop shit like this from happening is to just kill it dead really by actually progressing PGM2 emulation in MAME to the point that some lame ass MAME hack would no longer be required.
