I bought what I thought was New Zero Team to redump the bad rom. To my surprise it ended up being Zero Team 2000, which appears to be a rare final update of the game(?). I think the 333ROM chip should be shared between the 2 games (hope) so maybe it will fix that set as well. We will see.
The pcb is the V33 Type C Ver 2, the latest version I've ever heard of. Uberleet. That means it can be emulated immediately. Just kidding. Calm down.
It has a 3rd button you can hold down to do rapid attack so you don't have to tire yourself out button mashing, which is nice. The game plays really well, one of the best beat em ups ever I think? I can't get it to sync properly in my supergun so, looking forward to the emulation, but I was able to get some so-so shots. I'm waiting on a couple of parts to arrive before it can be fully dumped.
