@zyphuris55, MoonGBA is an Game Boy Advance emulator so it's able to open only *.gba roms. Shame that it doesn't work on Rhodium
I see there is same problem as with Kaiser - white box after rom loading. I can suggest you to try the newest 2.4.2 version from developer's website. I didn't try and I don't know if it will work on Kaiser or Rhodium. Unfortunately 2.4.0 is the only one which is english translated.
@xxviii, yep, some time ago I tried to play Pokemon (
) on PocketGBA but there were problems with ingame time settings. With MoonGBA there are no such problems. And about touch controlled pad question - Xiangpeng is working on it and there are fixes and improvements in newer versions, unfortunately in chinese language.
In general, it has some defects but MoonGBA is a great GBA emulator which works surprisingly fast, especially that its freeware and practically it isn't popular.
