Looking in the Argos sale catalogue today, I came across a Batman Plug n' Play game. I've been trying to find some screen shots online to show everyone, but I'm damn sure it's a new game. So I'll get to the point of this topic:
I assumed all PnPs used either single chip NES/MD/2600 hardware, such as the Radica/EA Sports MD based ones or the Atari Jstick with built-in games. But what about all these other PnP jobbies such as the gungames, Spongebob, Spiderman, Bratz dancemat etc? Anyone know if this is custom hardware being used, or are these running on, say, the MD-on-a-chip? The graphics do look fairly basic though.
This is the best listing of PnPs I could find quickly: here.
