Space Invaders and Tetris have an Elan EU3A05, but Golden Tee has EU3A14; it looks similar but is a larger die. Klaus sent me a vtech laptop board about a year ago that had an EU3A12.
I got Skateboarder but haven't deglobbed the CPU yet. It also has a ROM with TSOP48 pads, but all 16 data bits are connected, unlike the others that were only 8 bits.
I've got a CubeWorld; the plan was to transplant the LCD into a Microvision, but I haven't gotten around to that yet. I can deglob the CPU and see what it is.
I bought the Frogger plug'n'play and Snowboarder, but the guy selling Snowboarder refunded my money because his wife donated it to charity and I'm waiting for another cheap one. I haven't bought Ping Pong yet.
