The Wildfire I got was busted. I was hoping it would be an easy fix- most of the time those old games have battery corrosion which can be cleaned up, or a broken wire, but I couldn't get it working. I pulled the chip and tried to dump it electronically, but I couldn't get that going either. So I'll decap it and try to match the ROM bits to the patent ROM dump and see how they differ.
The pinout is slightly different from the datasheet- it looks like VDD was moved from pin 12 to pin 2, and pins 2-11 were slid down one spot. All the other pins seem to be in the right places.
