A latency-hating emulator of: the Acorn Electron and Archimedes, Amstrad CPC, Apple II/II+/IIe and early Macintosh, Atari 2600 and ST, ColecoVision, Enterprise 64/128, Commodore Vic-20 and Amiga, MSX 1/2, Oric 1/Atmos, early PC compatibles, Sega Master System, Sinclair ZX80/81 and ZX Spectrum.
I just tried opening some Amstrad CPC
.SNA
files and all reportedAfter a few minutes I thought, maybe snapshots are only supported on Speccy and not on Amstrad.
I searched but I couldn't find a list confirming that or in fact any kind of list about which file formats are supported for which platforms.
