It would be such a shame if GPEngine is no longer being worked on. If the developer is no loner making it then would he be able to pass it on for someone else interested to work on it. I think the PC Engine version of SF2 will be the best one running on GP32 (apart from maybe the Master System version). As someone said, if that "graphic garbage" can be removed or mostly then the emulation will be nearly perfect. I have also heard that other PCE emulators on other platforms have the graphic garbage when playing SF2, is SF2 a hacked game or something, or used hardware tricks on the PCE, i heard it is the biggest game on there.
