I guess you could expect a port of madrigal's simulators.
The source code is available and has been ported to psp, Xbox, Famicom mini and so on. It should run well on those limited devices. A port for gcw zero could be great also.
It has been ported through Retroarch on all of those. The license of Madrigal's forbids :
- Derivative works (so i can't port it)
- Making available older versions (requiring said porter to keep up with releases)
And more bullshit.
Hiban has released QuarterSnatch for the LDK/RS-97, which is a G&W game with some enhancements.
If you really want to play the other games, the G&W Gallery games (including the GBA sequel) are a decent way of playing those.
