Major Problem - Need Help!

[Eiji]

The following games no matter what I do won't boot up on my PSX but they work in emulators:

Duke Nukem: Total Meltdown (NTSC/U)
Kingsley's Adventure (NTSC/U)
Puyo Puyo Sun Ketteiban (NTSC/J)
Return Fire (NTSC/U)
Shadow Master (NTSC/U)
Shooter: Space Shot (NTSC/U)
Wipeout 3 (NTSC/U)

None of them are rips, they are full images, I've got over 100 PSX games and I know how to copy PSX games but no matter what, the above games fail to boot on my PSX no matter what CD-R media they are on.

They either never get past the black PSX screen or just crash after the black PSX screen disappears.

If it helps, I have a SCPH 5502 PSX with a stealth mod chip.

Is there any way to fix up these games?

Thanks for any help.
