Hiya yes the PS1 Had a Mod Chip. Tried everything you said, Tried it with new discs too(Tuffdiscs) and another type of CD-R and I still get the same problem I have used Nero, Clone CD, DVD Dycrypter and Alcohol 120% and I just get the same problem of it saying "Insert Playstation CD-ROM" Dunno what else to try.
