Recalbox OS running off an ancient 4 GB USB 2.0 Drive, with an additional 128 GB USB 3.0 Drive containing ROMs and Media.
At the moment over 40 systems running stable, even the more ressource demanding ones like the PSX, PSP, the Dreamcast or the N64.
Next up I would love seeing a PCSX2 libretro core (for PS2 Emulation)...
Emulation System is my old gaming PC I built in 2005.
