I'm bored so I just felt like starting to put in some ROM offsets and other information I've found on this great SNES strategy game. If people are interested enough in graphics/map/etc. hacking and I have the time/patience I might add more material. There has already been a great English translation, so I haven't focused on scripted events much, but here's some stuff I've found..

-Virtually all of the compressed graphics/map data is stored using the same Squaresoft LZ format as Chrono Trigger. Most of the graphics is 4bpp, but there's a little 8bpp stuff and some 2bpp text. Use format 12 in Lunar Compress's sniff/decomp/recomp files.

-The SPC audio samples are roughly around offsets $46A00-$66200,$72780-$7FF80, and scattered across parts up to $B8000ish.

-Uncompressed data is, of course, easily discernable with a graphics reader like Tile Layer Pro or SpriteView, but if you need help finding it go to most of $140000-$190000 and $200000-$260000. Again, mostly 4bpp with some 2bpp text. There are also some tile formations I've noticed that are uncompressed, but haven't looked super-close at.

-As for the compressed data: $8397a-8b584 is a series of backgrounds, rendered in the usual 2-bytes-per-tile format, followed by a few graphics, then some more backgrounds from $90200-$a8120. $B0200-$e40f3 = graphics, $e40f3-f17ac, $f2183-$fb489, $fb73d-$ff620, and $100200-$134ef5 are various maps. $266820-$280292 is a block of graphics, some 8bpp, and elsewhere in the $280000 bank plus the final bank ($2F0000) there are some title screen/island graphics. (Interestingly they have a "Copyright 1995 Square" as well as the 1996 one; I know it was released close to the start of 1996 so it was right on the bubble.)
