The NES File header (ines hader) need to be added to the PRG ROM. Because the header does not belong to the ROM but is needed for emulators. (+0x10)

(all of these here are add 0x10 for header)

Table for progression
ChoosePatchTransition the pointers to path tables are at 0x29a5 (3 pointers, 2 bytes each) the path tables are at 0x29ab, 0x29b4, 0x29ba, 0x2129 the data in those tables is 010000000000, 020302060001, 070600080000, 0400000500000B00000700010705000900000A00000A00000C00000C00000D00000E 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) ScreenNames and PointerValue 00 Start 05 Restart?? 07 Debugg 08 Map swamp zyklops 09 Prayer Screen 0A-0B PW Screen 0C-0D Ending 0E Stage 0 3e450 0A > 07 Will make name screen debugger screen
If you like to skip the map after stage one: 0x4171 Table of Screens after Boss (orb table??)

Things I would like to research and add
Sprite assembly format and animation format. May be a enemy editing file.
