Here you have Impossible Mission for Commodore 64, Sony PSP, Nintendo DS, Sega Master System, Atari 7800, Spectrum 48, Amstrad CPC, BBC Micro and Acorn Electron. Every version is slightly different. According to Wikipedia there is even a version for Virtual Console on WII, but this is a straight port from the C64. The gameplay is by me on various emulators, except on PSP, DS and Atari 7800 versions. The PSP version was recorded by Pete2Shakur and DS and A7800 were segments of longplays that can be found by following the link presented in their segment of the video.
