The aim of this project is ability to use files from ZX Spectrum emulators directly on original ZX Spectrum without modification of these files. There are lot's of ZX Spectrum programs and games in various formats on the internet and is not easy to use it on real Spectrum. This project is writen in Z80 assembler and runs on ZX Spectrum with IDE interface (most of IDE harddiscs, CDROMs, ATAPI ZIPdrives and CFs can be attached to this interface). Emulator files are stored on ISO9660 filesystem which is easy to understand and implement. ISOs can be stored on CDROMs (as usual) or stored like images on HD, CF and ZIPdrive.
