The chips used in the RiscPC and later machines were so much different that a lot of earlier software did not run anymore, a good moment to write an emulator, !A310Emu. It turned out that some games and demos required features that I could not add to this older version. The archive contains the emulator itself, and a few example setups. You can add other OS'es than version 3.11 too, it recognises them automatically. Tested with Arthur 0.30 and 1.20, Riscos 2.00 and 2.01, Riscos 3.10, 3.11, 3.19, and 3.20, with memorysizes from 0.5 Mb up to 16 Mb. The Readme file has more info where to get more software to revive those days. The emulator can be used both in multitasking and singletasking. Supports 2 Harddisc images up to almost 500 Mb each, HostFS and it passes through Midi commands, if MIDIUSB is active in the host.
