Thanks for the suggestion, Cyartog959, but I think anything beyond the fourth generation is kind of the opposite of "simpler" for me. I tend to like working on games from the 1980s and the first half of 1990s, or games with similar aesthetics that would've fit in that era, Nox Archaist being one such example (I've only released the overworld so far, but will eventually get around to everything else some day).
Well, that's fine, and I know you prefer your more simpler routine, but there are others still in need of mapping, and that game may have to be sometime later. A good DSi compatible emulator can do the trick for it, though, I understand you're not versed on that.
As far as some have played, being a bite-sized content-packed RPG for DSiWare, I can presume its maps may not be quite too large/complex, 'cause it had to adhere to the tight limit of 20MB at the time.
Mappers do have to cover all corners in game cartography history sooner or later.
