Yep, looks like all that data is correct (unsurprisingly), but I'm still trying to figure some pieces out.

Here's what I've got so far.

6 byte data at 270200:

• The first three bytes (only the first 7 bits of each byte) are the tilesets to use, don't know what the high bit means
• The next two bytes are the two tile assemblies to use. I don't know why there are two
• The last byte I don't know. I assume it's pointer to a palette set somewhere
• The only big anomaly, which unfortunately turns up a lot, is that some of the tileset pointers are set to FF, which isn't a valid tileset. I really don't know how they work, but they're pretty important.

Tile assembly - They are indeed 2 bytes each, I've got abbbbbbbcdxxxxxxa figured out

• a: which of the three tilesets is used, these two bits are added together, so 11 equals 2 not 3
• b: the tile index 1-127
• c: vertical flip
• d: horizontal flip
• x: No idea... yet

Tileset pointers: these are just long pointers, but for right now I'm working on the assumption that everything below bank E7 is uncompressed. It seems to be working, but more testing is needed.
