There isn't a program which will tell you if this is a rip or full. For PS2 maybe, but never for ps1. And like the program name says, DVD Scan Lite v3.7
A PS1 can only read CD Roms so there is something wrong................
One rule of thumb though is that most uncompessed PS1 image files that are under 100MB are rips.
PS1 Games under 100 MB are mostly 2 D Games, if they are full and packed.
If you downloaded one of these games from an emusite ( Ridge Racer 1, Ridge Racer Revolution, Ridge Racer Type 4, Soul Edge, Tekken 3, Dead Or Alive, Fighting Force 1, Grand Theft Auto 1, Grand Theft Auto London, Grand Theft Auto 2, Driver 1, Worms Armageddon, Agent Armstrong, Cool Boarders 2, etc. ) they will be 100% rips. These games are the most commercial rips which you will find on emusites. And rips over 30MB you will not find normally.
