I can suggest to make a MUI version of the most famous emulators, like UAE, MAME or SNES9x.
Actually Frodo is also in MUI version:

It's rocks! I really hope to see more "MUI versions"!

Many emulators are "optimized" for MorphOS, often they must used by shell, or use non-native libraries (like the Mame 0.71, you must install some compound from Aminet).
Also some GUIs are done with ARexx (like UAE gui), and it's not included into MorphOS 1.4/1.4.2 distribution. And not all Pegasos user's, like me, have AmigaOS 3.1/3.9, and have manner to retrive easly the arexx library (it's not on aminet ).

I have nothing against Shells, but is easy make wrongs digit all commands and parameters by text (but it's still great for other works, I ever use it to de-compress archivies...).

I use often Pegasos for emulators, so I can suggest:
Mame, UAE, SNES (altrought exist alredy a good GUI).

Also, exist a good ZX-Spectrum emulator for Amiga 3.1/3.9 or MorphOS?

Ehhhm, there is already a great MUI GUI for Snes9x done by Tokai.

and don't forget that MAME has a very nice and informative inbuild MUI GUI already!!!


and fully reimplemented rexxsyslib.library will come with morphos1.5 i heard :)

just another info:

it also depends on the emulator/port.

e.g. for snes9x or mame it does not make sense to make such highly integrated MUI GUI like in frodo. That has a few resons. e.g. MAME is heavy updated... and integrating a MUI GUI into official source tree is not possible easily, because the source has to compile on all systems. So the only possibility is to code a frontend (which uses MUI already) which can be easily linked.

That's what I think. :)

but feel free to compile snes9x and integrate snes9xstarter. snes9x sources are available and a bit older snes9xstarter source code is available on mdc.morphos.net (maybe i'll upload the new version when i have time).

Haaa! Finally a new Arexx working!
Anyone whitout a AmigaOS3.1/3.9 have some trouble to make work Arexx progrs with actual release...
