Generally, I use RetroArch with the cores Recalbox uses on all of my emulation rigs. Most of the heavy lifting is done by the RetroArch cores for Final Burn Neo, Beetle, FCEUMM, Gambatte, SNES9x, Genesis Plus GX, PCSX Rearmed, ParaLLEl N64, mGBA, Flycast, and PPSSPP. Most of my devices run Emulation Station, using ES-DE on Windows when not playing online matches with Fightcade.
