Forum:Shin Megami Tensei Version differences

So I've been playing through the classic SMT games this past year and every once in a while I find something new to read about. Today I found out that Danichi Nyoari is an exclusive demon to the PC-Engine version of Shin Megami Tensei 1 and also that the PC-Engine version has some cutscenes. This made me wonder what other differences there are between the SNES, PC-Engine, PSX, Gameboy Advance and Sega CD versions. Does anyone have a list of differences? Or do anyone one of you know of other differences in any versions?
