Well, I 'sorta-recently' bought a 32X without any leads, along with a Mega Drive and a Mega CD (Or genesis, for you Americans). Now, it took a few weeks to get all the leads needed for the 32X, and the other day I plugged everything in and switched it on.
First, note that the Mega Drive and Mega CD work absolutely fine, with no problems at all. Anyway, I get the Mega drive BIOS screen and stuff, but nothing else, most of the time. Barely any games show signs of life (Mega Games 1 seems to be the only thing that works in the 32X fine), but instead give out a black screen. This includes both Mega Drive and 32X games by the way, even though the mega drive games work fine on a mega drive. Doom is the only 32X (Out of the two I have

) that begins to work, but doesn't do it very well.
I've managed to get the SEGA screen, the copyright info, and the title (Although this is sometimes severely glitched up, covered in black pixels and sometimes unreadable). Sometimes, the screen goes blue, symbolising that it's locked up, so I have to take out the cartridge and give it a dust. I've managed to get to a glitched menu, but am unable to play the actual game (As it freezes as soon as you select a difficulty), but I have been greeted with a black and white screen for whatever reason, before now.
So my question is this; rather than wasting £30 on buying a new one, can someone suggest a solution to solve these problems? All the leads have been tested fine, the cartriges too (Although I can't test out the 32X games, since the 32X is broken, obviously).
