The guy who posted this let me know it has 617 games. I can’t say I’ve ever seen a menu like this one (which appears to be based on Marvel Vs. Capcom 2’s fonts) nor that number of games in a Pandora’s Box clone before.
This is a Game Elf (or Blue Elf) they’re similar to PD’s but released awhile ago, they are inferior compared to the PD offerings now days. Not sure if they still make them but they pop up online every so often.
Thanks for identifying it. I did see a Game Elf JAMMA board show up locally, I think it was an older one with 100 games. Even though I don’t have anything JAMMA compatible, I’m thinking about picking it up because I find this sort of hardware fun to collect and check out.
