One thing that should not be understated with this thing is just how much art is traced / 'borrowed' Plenty of NeoGeo rips like these... 
It should also not be underestimated just how buggy these games are. I thought there was a bug with my input reading because Tetris doesn't rotate for the first button press on any piece. Turns out hardware does the same, first rotate action on any piece will make a sound only.
There's a video of the game in the other version of the system, where they changed the title to "Boom Blocks" (here it is called "Maze Pac" for some inexplicable reason - it's not Pacman) but the bug remains. Count the clicks, watch the rotations.
But yeah, it's called Maze Pac here... Also I added preliminary sound, which has the knock-on effect of making the controls work in the 8-in-1 select menu, so now the Sports games can be selected. Still need to implement a bunch of video features tho for gameplay.
