There's been some good Smash TV discussion here lately, so I'll add my latest project:
Here's where I reveal myself as a Jamma noob - I'm trying out the Mike's Double Jamma adapter. It seems to be a very well made item, and works perfect except for one glaring problem in that it doesn't pass pin 25 through. Not sure if that's described right, but the device seems to take all of the pins from the game harness, and "split" them, allowing you to connect both boards, then switch between them. When I hold the adapter up to the light, I can see that all of the traces that do this. Literally every edge pin on the harness side has a trail that splits and goes to each of the corresponding pins for the two boards you're connecting…except for pin 25 (and its letter counterpart on the other side) which goes no where. In Smash TV, this translates to not being able to shoot right (direction right).
Starting from the left - 28 and 27 are grounds, 26 is for a button to switch between games, its going through a jumper and some other stuff. 25...nothing?!? I must keep all my enemies on my left side!!
Then every other pin goes through various components and then to it's two counterparts on the othe connectors:
The only other issue I can see is that by default, you swap games by pressing P1 and P2 at the same time. In Total Carnage, the same button is used to drop bombs. I'm afraid that during a 2 player game, it might be easy to be bombing at the same time and accidentally swap games. I think the pin 26 button disables the P1/P2 swap function, but I'm not sure.
Other than that its fine…no issue with the video with my single power supply, or anything else. Anyway, I'm going to work on it more tonight.
I also want a mod that makes the Smash TV announcer say "SKATE OR DIE!!!"
