But yes as David says- an .exe compiled normally will only run on windows (or emulated environments like WINE but thats besides the point), but MMF2 offers support for exporting as Flash, Java, & mobile Java as well as a few others. And if these are supported by the wii (I have no idea), they would work. I know you can create browser games that could run "normally" on the wii via the internet, with no console hacking involved!
