Hi have you tried any emulator on your Amigas? i have tried Sega master system games, and commodore 64 games and Nintendo and game boy and Atari 2600 and 7800 games. they work quite well on a Amiga 4000/030 but the commodore 64 music is way of, that is not something it can emulate very good, other than that it works quite well. I am surprised that it can be done on a 030 CPU
On my Amiga 4000/40/25 MHz I used to play lots of emulators.
Some of the emus you don't mentioned are pretty fun to play:
Nintendo Gameboy -
Wzonka Lad - Latest updates by me. The author released almost the full source code, but a vital file was lacking. I asked him to send me the file and he did. I removed the keyfile need and did some minor updates. You can also try AmiGameBoy - common engine with the AmiMSX emulator - very fast.
Apple II/IIe -
Apple 2000 - Very fast emulator for the classic Apple machines, although not all the IIe software works. I used to play hours with old classics. I have the full source code of the emulator, but I don't have much time to work on it.
ColecoVision -
fMSX - emulates the MSX slower than the AmiMSX emulator, but this emulates ColecoVision cartridges.
Oric Atmos -
AmOric - Pretty cool emulator of the Oric. Works nice but does not support disk drives.
AmstradCPC -
Ami-CPC] - another cool retro machine that I used to learn Z80 on thanks to the educational software available on funet.
Sinclair ZX Spectrum - [url=http://aminet.net/misc/emu/ASpEmu.lha]ASP - emulates 48K and 128K Speccy with AY sound. Works fine on AmigaOS 4. I even have video on it working on my AmgiaOne. You may need to run BlazeWCP or it will be slow on AGA machines.
Commodore Plus4 -
Flamingo - Another nice emulator. I loved reading diskmags and enjoyed the colors of the machine, although the games are crappier than on the C64, because of the lack of sprites.
CP/M
SimCPM - I used this for running some VERY old CPM software. Nothing fancy. The CP/M predates the other 8 bits machines, so don't expect much from it.
Of course there are many other cool machines that you can emulate on your Amiga. Most of the emulators are on Aminet, so just look there and enjoy.
