Is it possible to force a PS1 game ID to behave as PS2?

[eliankeil]

I’d like to ask the following: Is it possible to force the behavior of a game ID that is recognized as PS1 so that it behaves as if it were PS2?

Here’s the scenario: I have an ISO image with Snesticle and some ROMs. When creating the ISO, I assigned a made‑up ID (SLUS_000.09), and it works fine. The problem is that when launching this ISO from MMCE, it generates a PS1 VMC, and I haven’t found a way to make it behave like a PS2 VMC.

I know the direct solution would be to replace the fake ID with something else like SNES_XXX.XX, but this question came up and I got curious whether it’s possible to force automatic behavior for a specific ISO.

Thanks a lot!
