Feel free to do some digging.

PRG ROM

The NES File has a header (+0x10) to tell the ROM size. You need to add that value to the PRG offset to get the right address.


Sry a real ROM map might follow but for now I will paste the most interesting tables

0x1730 Table for noice and anitation.

 Table Format:
 AA BB CC DD
 AA=Stage
 BB=Block
 CC=Segment
 DD=Effect 10 Fog, 20 Animation Only, 30 Animation and Sound, 40 ??, 32-37 WaterEffect(flicker),56?? ,71 move a stage??

Table for progression after the map.

   (all of these are add 0x10 for header) the pointers to path tables are at 0x29a5 (3 pointers, 2 bytes each)
   the path tables are at 0x29ab, 0x29b4, 0x29ba
   the data in those tables is 010000000000, 020302060001, 070600080000
   the table for the area you go to after walking past a big map (not choose a path) is at 0x211d (3 bytes each, not sure how many)

The most insight in the game was from Opptomon
