Let's explore the world of esxDOS software for 48KB and 128KB/+2A/+3 ZX Spectrum computers (and compatible) with DivIDE, DivMMC, DivSD and MB03+ Ultimate interfaces.

Every piece of software is split into normal single zx-files with +3DOS FAT headers. You can copy and move these files both on your Linux, Windows or Apple computers as well as on the original ZX Spectrum.
The good news is that also games are starting to appear that natively support saving of positions and hiscores directly to SD and CF cards. The emulator files and similar legacy files, like TAPs or TRD images, are not needed at all.
