It's correctly detected, then it crashes when trying to open RTZCD.PRJ fopen(cdfs:RTZCD.PRJ, rb) open cdfs:RTZCD.PRJ [4] _fileSize = 43016792 _filePos = 0 Which is ~43MB big. PS2 just has 32MB (-ScummVM resources). Is that cause is trying to read such a big file? Does rtz work fine on other backends? Thanks! -max
