Thanks a lot for this new release! I've played it a little in Nestopia 1.36(*) and it has worked fine so far (it has a few slowdowns here and there when navigating by some menu options (specially when closing them again), but I think it's because the game's made this way).
The gameplay is unforgiving, I'm at level 10 and from time to time some enemies from early in the game still kill some of my characters with a single blow. It's one of these old grindy games, hehehe. But I'm liking it so far, it's very Dragon Quest in every sense and it has a lot of (retro)charm.
(*) how strange, I tested the game again with a more recent version of Nestopia (1.40) and I only get a black screen (the original game boots up without any problem, though).
