In response to the missing Street Fighter games, don't they incorporate some special chip? I also remember them touting being large ROM sizes like 48-mbit / 6MB, so maybe it has something to do with how much data the cart can move from storage to the area where a game is read to the console. Maybe that middle area is too small to load Street Fighter anything into it.
Who chose these games? There are good games, but they put in some obscure stuff like Zero the Kamikaze Squirrel, Incantation, and UC Cops. I'm not saying those are bad games (Incantation deserves a bit of yawning, though it looks pretty), but it's such a strange selection. It's like a mix of Euro cult hits (Top Gear, Turrican), broad appeal titles (Mortal Kombat, Mario), randomness like Jeopardy, and topped with some obscure Asian stuff most people who aren't deep into retro wouldn't know but might enjoy. Considering the shooty games on here, I am surprised they didn't put R-Type 3. Maybe it was a hardware limit issue.
