I'm wondering if these games saw US releases?
I've seen that Little Big Adventure was released as Relentless: Twinsen's Adventure for the PC, but I can't see any information about a PSX release. It isn't listed as dumped, or in the undumped section in the Wiki.
Also, X2 (AKA X2: No Relief) Saw an NTSC-J release. Did it miss out on a US release? Again, I can't see it as a dumped disc, nor in the undumped wiki page.
