Hopefully by April 2nd emulation rule changes will be occurring.

RetroArch will be banned in favour of DuckStation and it will become the recommended emulator (that's if final verifications go well).

The BizHawk emulator will be minimum of 2.7 and not 2.4.1 due to many core changes but also it will have an alternative PlayStation mednafen core called "Nymashock" which gains some more performance which might help low end.

And also be sure to join the Discord.

Edit: BizHawk might actually be minimum of 2.8 as that emulator is getting an update before the planned date.
