Yeah, I'm pretty sure it's based on Adamem. If you update the core or not, it's still a fantastic emulator that you obviously put a TON of work into. Most of the Coleco emulators I used will NOT run Dragonfire but AdamX runs it perfectly. Even in Adamem, I believe I had to switch it to PAL emulation to get Dragonfire working. Otherwise the guy doesn't jump high enough. Also, most emulators don't support the Super Action controller buttons! MESS has a dip switch for them, but it doesn't work. Apparently there's very little interest in the Colecovision, probably due to the fact that it specialized in arcade games, which of course everybody plays on MAME. All the buttons on AdamX are customizable, where you have to have some knowledge in programming in order to map the controls in Adamem. Anyway, I wanted to make it clear that I'm just reporting a bug, not complaining at all. So thanks a bunch for your hard work!
