I played around with GBA tilemaps today and wondered if there wasn't an editor which lets you edit those maps. There are several Tile Editors, but rearranging them into a new tilemap seems like a royal pain if one only has a hex editor for the task. I looked through our database and only found a tool for SNES tile maps specifically and one named Tiler which is DOS and seemed to crash on me when I pressed a mouse button (and it even says at the start - you are running on win, expect crashes).

Are there other ones I overlooked? Does no one else feel the need for such a tool? Maybe other tools have this stuff built in and it's not explicitly mentioned in the descriptions, so I didn't try it out.
The reason I'm played around with those is that I need to change the menus in DQM somewhat. I think I found the tilemap in ROM, but it would be best if I could just load it into a tool, imported some tile data and display the map right onto the screen. One look and I'd knew what I found :p

Djinn Tile Mapper is a very nice program for that. It's in the database, only someone put it under "Script Extraction/Insertion" instead of "Graphics Viewers/Editors."

Well, it allows you to view text as it appears in the ROM... But other than that, there's no features in it that have anything to do with text.

Ok. I moved it to Graphics Viewers.

You are wrong. Text editing is available. With "Get String" and "Put String" buttons DTM can dump the text string and store it back.

-Subject-
I have a program which can generate map, tiles and palette from BMP and vice versa. It supports NES, GBA (4, 8 bit) and Genesis maps and tile formats.
You need to dump the map and tiles from a game to external files, then open files in the program to convert.

There is an image received from map, tiles and palette of Teenage Mutant Ninja Turtles title.
