Heh, speaking hacking Pokemon R/B/Y/G - a friend of mine created a map viewer that displayed the maps of any version of the first generation games according to the map headers that appear in the game. I know, been done 1,000 times already, but he's always interested in learning by doing things that have been done already a million times (gameboy emulators, etc). I'm sure he won't mind posting a PM, since I thought that maybe you'd be interested:

Me and my map viewers, huh? That one's theoretically for all versions of Pokemon R/G/B out there, so Japanese, English, whatever, though I've only tested it with R/G Japan, B Japan, and R/B English and German. It displays maps by their map header, starting at the first one (Pallet Town) and going up all the way to 240-something, the last one that's recognizable as a map being 230 I think.

There are quite a few "garbage maps" in that list - like, 3/4 of them? - which don't show anything resembling a proper map, but their map headers look like they could've been proper maps of caverns, routes, houses, etc. once (sensical map size, tileset number and stuff) - also, some that display as garbage in the Japanese versions are actually used in the western versions, like map 199 which is part of the Rocket hideout in Celadon City. But then again, all that could just be my program fucking up and reading true garbage from the ROMs, I really don't know...

All that said, if you wanna try the thing out, here's what I have so far: http://magicstone.de/dzd/random/PKMapView.rar[/quote:9275e41dad]

And a follow up PM:

Sorry for the rapidshit, but I'm out of proper internet for the moment (again -.-). All the messed up map headers have been fixed - turns out it WAS a bug in my program (pointers weren't being calculated correctly), but there still are ~20 or something gaps in the list, which now point to garbage instead of a valid header. Guess they did hold proper maps once, but don't do now anymore. Also, controls: A, S, D, F are 10 maps backwards, one backward, one forward, 10 maps forward, the cursor keys allow scrolling the map in all directions. Oh, the data that was originally written to the console window (map and tileset headers) is now shown in a seperate window ("Map"-&gt;"Show headers"). Hope I didn't forget anything...

tl;dr there are some gaps within the list of maps - so is it true that there could've been maps there at some point?
