Emulator engine
This portal uses EmulatorJS with cores for GBA (mgba), SNES (snes9x), N64 (mupen64plus_next), PSX (pcsx_rearmed), and GB/GBC (gambatte). All emulation runs locally in your browser; no game data is sent to any server.
Legal disclaimer
This portal is strictly personal. Only ROMs dumped from physical cartridges owned by the operator are used. No ROM files are distributed through this service.
