LOL, it's that bad eh? Shame really! I seem to remember playing Turtles Tournament Fighters at my pals house years ago, so I might try and get hold of it!
As for Tec Toy - they are official releases - Tec Toy were licensed in Brazil in the same way Tonka were (unsuccessfully!) licensed in the US. Tec toy released most of the sms games over in Brazil that were also released previously in Europe. They also did quite a few game hacks with their own characters, and a lot of Game gear ports (sonic blast wasn't actually a tec toy deveoped game, but a port from the game gear). I think I've got around 20 - 25 Tec toy games, and actually have a couple more on their way as we speak!

I also have a Tec Toy SMS with over 100 games built in, most of which are euro games, some are Portugese games.
How did the pirate carts of sf2 look on the NES then? It'd be interesting to see a couple of screenshots! And yeah, I wouldn't mind getting a famicom, but they aint quite as easy to find over in the UK! Plus am totally skint right now, but come pay day, maybe....
