SPEmu128Spectrum 128Kb software emulator, it is EXOS compatible, required at least 192 Kb of RAM (ROM Version 160Kb). 30-40% of Speccy 128Kb programs run on the emulator. FYI: there are many Spectrum programs which writes to ROM area on real spectrum, so it can happen that a game is running on the spectrum emulator but overwrites an area which can cause problem later, so if a program is not starts after another program, then please reset the emulator, and try it again (this problem does not occur with ROM version). The emulator accept SNA and TAP files, and real Speccy tapes can be loaded also.
The package contains 2 files:
SPEMU128.COM - normal EP executable file
SPEMU128.ROM - ROM file, this ROM file should be inserted to any x0-x2 segment (eg 30h-32h, 40h-42h) in case of EXOS 2.1 and at any continous 3 segments in case of EXOS 2.3 or later.
