Finally RetroArch can be played with 2 players.
been waiting for this for long.
also i can now apply shaders which makes those old 2D gamesl ook great.
the only downside is PSX games do not run anymore with R3,
PSX ReArmed used to work my psx games in R2.
now neither PSX ReArmed nor the new core BeetlePSX run my psx games.
i get a PS4 error when i used PSX Rearmed.
as for Beetle i get a message saying scph1001.bin is missing.
any adivces on how to deal with that ?!!
