EmuZWin also support new snapshot format *.EZX with documentation.

But this format is supported only in EmuZWin emulator

Actually I need use any snapshot format for SAVE/LOAD on real ZX Spectrum with IDE. I developpe for DivIDE interface new BIOS rom with NMI menu + task manager. Each task is loaded or saved to CF card in 48kB SNA format. I need on ZX128/256/512/1024 models use complette memory for correct work. BIOS can detect ZX type+memory size(ZX48/128, Pentagon 256/512/1024, Scorpion 256/1024, ZX Profi....) and save each task to one file with length = zx memory size(uncompressed raw) + additional info(registers). Ideally as fileformat compatible with ZX emulators.
