Hopefully this gets your attention?
Well spotted (screenshot on EAB), thanks, I should fill that gap that you pointed out in the map. I got way critical priorities on the queue right now regarding 3rd party controls on real hw. But the issue is added to the report list, thanks for your post.
Also, worth mentioning that the goal was to provide a playable version of the original Castlevania but with an Amiga flavor. Not a port of the Sharp X68000 or PlayStation "Castlevania Chronicles" game, it only happens to use a bunch of level tiles and sprites from that game.
I hoped that at some point I would be able to get rid of all assets remaining of that X68K game, like what Amiga's Rastan wonderfully did (Amiga assets tailored for Amiga specs). Or the new Sonic GX game for Amstrad Plus/GX4000, which is not Mega Drive, Master System or Game Gear version, but something that was tailored to play to the strengths of the machine in question. ;)
