• 0x3B00 - 0x3B31 (0032) = Room bank numbers B (levels 1-30 are in bank "5"; 31-50 are in bank "6")

When loading a level, the game switches in the appropriate bank B to the PPU, then reads L bytes from 0x0010+P into RAM 0x723 (see Room Data below)

As a point of trivia, 0xEAEC - 0xEFFF features an unused copy of the level data in 0xDAEC - 0xDFFF.

A "Room" consists of 16x16 tiles, of which only 11x11 are "inside the walls" where Lolo can walk. Tile types are listed on the RAM Page and take one byte each. Room data is mostly rasterized tile data, filling in left to right bottom to top. But it is partially compressed (as you can see above, no room's data is a full 0100 long). Bytes with high bit 1 (F0-FF) are not individual tiles, but instead RLE directives. For X in 0xF0..0xFE, the game will copy (X-0xF0+2) of tiles from the row below the current row (or 0x00==black, for the bottom-most row). 0xFF is distinct from these, and is followed immediately by two bytes, a length L, and a tile type T. The game will expand these three together into (L+2) T's in a row. No RLE directive crosses a row boundary (if editing the level data, attempts to do so will trigger a buffer overrun in the level decompression logic and corrupt ram, including that used immediately by the decompression routine itself).
