I won a magical tetris challenge off ebay for like 38 shipped. I just got it and plugged it in, everything works perfect, no flaws at all except in the actual tetris game. I get no sprites inside the tetris grid. other than that everything is fine, any idea what to check, im gonna try and reseat the 2 chips on this board. (yea that didnt work.) I do get some flickering lights it seems like inside the grid, but no pieces, I can preview the next piece coming but once the piece starts to fall I get nothing. The 2nd player side shows like 3 blocks but thats it, nothing after that, and it only shows those on the floor, not falling.

Send it back. I have one, but I have not found the schematics online. And so much of it is ASIC chips, I doubt it would be easy to fix. They are not common, but they do show up periodically. Wait for a working one.

Just my $0.02.

so I guess im stuck with this, guy never responded about a refund, at this point dont care really, it was cheap. Anyone have any ideas how I may go about fixing this?
 
You might want to find somebody who fixes N64's. MMTC is just an N64 motherboard with the MMTC cartridge stuck on it.

Based on your symptoms, it sounds like one of the sprite generators is hosed.
