I don't use PCSX, but i have the CIA handy on my internal SD and i could test it.
I loaded beyond oasis with picodrive and car battler joe with gpSP, both with no problems.
Both have dynarec enabled in the menu.
Reading closer, I saw "Gateway", so that explains why it works then. Gateway isn't using 11.0 FIRM. If you open them on an emuNAND with 11.0 FIRM (for example, with Luma), it'll crash and reboot the system. I just tried it myself.
