If anyone has information on the undocumented ones then please feel free to contribute.
VER - Always contains the dword 2, and then a following word with the value of 0x003B.
IVER - Same with VER , except the following word is 0x000A.
IVE2 - Same as VER, except the following word is 0x000B.
TILE - One tile takes up one word (16 bits). Therefore, there are 65356 possible tiles for every tileset. The size of this section is: ((sizemap ^ 2) * 2) bytes.
MASK - Seems to be a few hundred bytes of 0xFF.
TRIG - Posted partial format in previous topic
WAV - Stores WAV files, not sure of specific format as of yet.
STR S - Null Terminated table of strings. Any unused string slots are filled with 0x0208 (some kind of filler, the pattern of 08 02's are null terminated as well). Strings start at the bottom of the section and work their way to the top.
