Arrow Reason for black screen with PS1 backups CD-R discs

Reason for black screen with PS1 backups CD-R discs

Note: Posted it as separate thread since it will be lost in multiMAN update thread.

Just confirmed something, there are bad dumps of PS1 game discs around. They may work with emulators on the PC and such but when put on the real console or in this case the PS3 they give problems.

The bad dumps usually have been ripped incorrectly, and for example a good disc image dump of "MegaMan X6 [SLUS-01395]" has these properties "MODE2/Form1/2352" as many (if not all) the PS1 discs.

I found out a bad dump of the same game "MegaMan X6 [SLUS-01395]" with these properties "MODE1/2352", after burning and testing the disc image 2 times, the result was a black screen after trying to boot the game using multiMAN v02.08.01 (XMMB / File Manager) not even the PS1 logo came up, and Swapping disc or using "Breaker Pro" didn't work at all.

So I decided to test this "bad dump" on the PC with pSX 1.13 emulator, and it worked there, because the emulator doesn't actually care about the disc format, the emulator just looks for a disc drive to get the contents from, so basically if there are bugs in game, they might not even be related to the emulation, the one responsible for the bugs in this case would be the disc image.

Now, after I burned the proper dump "MODE2/Form1/2352" to the 3rd CD-R disc and tested it on multiMAN v02.08.01 everything went smoothly

I hope this helps people getting black screen after burning backups to CD-R discs.

EDIT: No wonder why Cobra have this on their Documentation:

Allowed format are:
· Iso (mode 2/2352).
· Cue+bin. Data track must be mode 2/2352.
Cue+bin+wav is not supported: audio tracks in wav files are ignored.
SeeYa!
