The new dumping guide by Vigi is now available. Our method of detecting offset in audio tracks has already proved to be correct (for example, audio tracks in PAL and U/C editions of Mortal Kombat Trilogy now are the same), so you can safely dump every disc with audio tracks.
The next step is dealing with LibCrypt-protected discs and making new CD layout format, which, like cue, will allow to keep tracks separately from each other (clean RAW files), but will also have support of subchannels and sessions.
