Yo raph, i got some OOOOOOOOOOOLD c64 tmnt roms, i don't think their official, but they're pretty...interesting.
It's 2 parts, the first one starts in the sewers, the game is basically a top view shooter game, like akari warriors but tmnt-ish
you have to fight foot members and alligators (HARRRR BUDDAY THIS SIE FUNNAY, ALLAGETORS = SEWERS, GETS IT?HAH,.1O3P1!) and then you go up to the city...then i got killed
The second part's viewpoint is a bit more different but gameplay is the same, you start in a street and gotta climb to a building, fight some more foot, haven't played that one much.
So anyways, if you agree i'd like to send you those so that you can put em in your site
if you don't have em already, that is.
