sprtools (t.a.g.)

Wow. You've gone through all the posts about my own tools for my own SPR file format ! I'm impressed.
It may sound an odd idea to run your own file format when doing a video game. This is mostly motivated by the odd memory structure of the DS video chip, tiled to the bones. '.spr' file are mostly a VRAM dump with IFF-like headers, created by my SpriteEditor. "sprtools" are all the PC-side programs that manipulate those dumps, converting, extracting, recombining pixels and checking more complex data structures embedded within the file, such as the list of "free tiles" within a chunk of video memory.
