Emulators lets you run your favorite program from your old computer on a recent computer. You will find below a comparison of feature of the emulators and presentation for each emulator. My personal favorite Amstrad emulator is CAPRICE32 for msdos and for win9x. Though the others emulators are fine too. Winape32 for example is nice for programmers with its builtin assembler, disassembler and debugger.
