I didn't need to ask before cause i always used ePSXe 2.0.0, which is explicitly allowed. Though lately, i was switching to RetroArch since i can have multiple consoles on just one emulator; this one uses cores from other emulators, and one of them is actually a Mednafen one. Since mednafen is allowed, i was wondering if also using a mednafen core on retroarch is; so i can decide wether to keep epsxe in case i start running spyro again or not. Hope i chose the right place to ask, and sorry in advance if it was already answered.

I see no reason why it shouldn't be allowed. RetroArch just works as a fancy frontend to load the exact same mednafen which is allowed on these boards.

That's exactly what i was thinking, but wanted to be sure if i'll run the game again and get a nice time to submit
