Friend of mine got a Nintendo Game & Watch (reissue, not the OG) and offered it to me for free. But it only came with 3 games. So, we're going to need to change that.
The small soldered on SPI flash storage chip has to be upgraded to hold some more games but it became a decent little credit card sized portable gaming machine!
JTAG style debugging made this one a little bit more challenging but still a fun learning experience.
