(Just in case you were thinking otherwise, this *is* about the SNES version, not the GB port or NES pirate.)

For graphics and tile formations, uses Lunar Compress format 11 (a Konami format I've also seen in Parodius Da!, Gradius 3, Castlevania 4, and a small part of Axelay.) Mostly 4bpp with some 2bpps for fonts. All offsets are on a headerless USA version I have. Remember to try not to rip across banks (they're LoRom or 32K) or across long segments in general, or graphics get scrambled.
356A7-36C94 = introduction gfx
3E9F3-3F552 = Startup Konami logo graphics
40FD4-411D3 = Startup Konami logo tile formation
417DE-42538 = mostly fonts
458AF-46FCA = looks like some between-level character graphics
48000-4E638 = level 1 backgrounds
50000-51BC6 = level 1 boss graphics
5237C-55871 = level 1 tanker graphics and what appears to be some map data (perhaps also from level 1, it being in the same bank)
58000-5E86E = various character sprites
60000-674BD = level 3 background graphics
68000-6A5E5 = looks like some level map data?
6A728-6C2FE, 6C90C-6D6D3, 6D218-6FA68 = some object sprites
70F5B-74024 = some monster sprites
75A4E-77366 = some backgrounds
80000-81C17 = first miniboss in last level
88000-89D0E = last boss
90000-91417, 927E8-93C16, 94FEE-9660A = various overhead sprites
9A0C2-9B602 = uncompressed overhead-level player sprites
A1C93-A1DCF = missile sprites
A36C2-A56C2 = uncompressed overhead larva sprites
AA477-AAFC6 = level data (?) and some enemy sprites
B3200ish = "Choose Your Starting Point" and other overhead level graphics, but doesn't seem to decompress right
B4752-B5F52 = uncompressed explosion sprites
BAFDA-BB953 = overhead sprites
C19A4-C515B, C9AB1-CCAB9 = between-level tile formations and graphics
D8000-DE000, E8700-EAB20, F0000-F6CA0, F8000-FE860 = sound effects (no additional compression, which I've only seen in two other SNES games, Konami's Gradius 3 & Castlevania 4.)

If people are genuinely interested in hacks of this fine platform shooter, I'll try to find more offsets...
