Sonic 2 (bootleg of Megadrive version) [caius]

needs correct coin logic (mcu sim?) hooking up for this bootleg, looks like a nasty hack, time counter is accelerated (so really you don't have long to complete the levels) sonic lives logo is hacked out and replaced with the credit display.

it boots with 2 credits, so you can play it right now, but can't add more credits.
