Another thing is that I don't think the ISO of the game floating around on the internet matches the CRC of the ISO ripped straight from the retail disc with TurboRip.
If somebody with the Super Raiden retail disc is willing to rip the Track02 ISO with TurboRip and send me the file, I can compare it to the two other ISOs I have, and I can determine which is the REAL ISO (and therefore which ISO the patch should be made for). I'm hoping it's not like the Ys IV deal where there are two slightly different versions of the disc... that would complicate things.
I just went to the "Paradise for Australian Birds" and downloaded a copy to see if there was a problem.
After extracting the .wav & .iso files using my patched-and-fixed Windows version of bchunk, the files all match up with the sizes reported in NightWolve's TOCFixer.
Track-02.iso is 22,839,296 bytes long, and has an MD5 of "ca25dc973a01589d857e38b951f6f508", and a CRC32 of "3b67af74".
Is that what you're seeing on your copy of the original .iso?
How are you extracting the individual .wav & .iso files from the download?
