@mitu Sorry for the delay, I didn't receive an e-mail notification about your reply or maybe I miss it....
PR is submitted to update the documentation.
Have you verified that the dumps are correct and they match the redump.org site checksums ?
I have just checked checksums for several games and they are correct:
Medal Of Honor (Single-Disc)
Redump : SHA-1 - 99f46eec7a8abe548b376f3c920353ab1f642de2
Generated .bin file:$ sha1sum "${HOME}/RetroPie/roms/psx/Medal of Honor.bin"
99f46eec7a8abe548b376f3c920353ab1f642de2 /home/mylogin/RetroPie/roms/psx/Medal of Honor.bin
Metal Gear Solid (Multi-Disc)
Disc 1
Redump : SHA-1 - 3daa7fbdf69e232e76b593951950c34be930b299
Generated .bin file:$ sha1sum "${HOME}/RetroPie/roms/psx/Metal Gear Solid (Disc 1).bin"
3daa7fbdf69e232e76b593951950c34be930b299 /home/mylogin/RetroPie/roms/psx/Metal Gear Solid (Disc 1).bin
Disc 2
Redump : SHA-1 - 578bef4fb45a4c20a7dd5f6645b474a5180aae04
Generated .bin file:$ sha1sum "${HOME}/RetroPie/roms/psx/Metal Gear Solid (Disc 2).bin"
578bef4fb45a4c20a7dd5f6645b474a5180aae04 /home/mylogin/RetroPie/roms/psx/Metal Gear Solid (Disc 2).bin
Which CD unit are you using to dump the discs ?
I'm not sure so I'm not going to say anything wrong... The script is mainly a wrapper around cdrdao and toc2cue utilities so I let the cdrdao utility do the job to generate the .bin files.
I see other scripts on the Internet but they were buggy or not enough user-friendly as mine. To rip a disc, I just want to :
Insert the disc
Start the script given the name of the game and eventually, its number of discs
Restart EmulationStation and have fun
