Welcome to the Might & Magic II (Amiga) reverse-engineering wiki. This page is the recommended reading order — pick a path based on what you want to do.

Choose your path

I want to understand the project Overview — doc map & address rules dat Files and Formats — every .dat file Runtime Memory Map — A4 workspace Full Analysis — long-form narrative

I want to edit game data MM2ED Editor — ImGui editor build items.dat Format · monsters.dat map.dat Format · event.dat Format RE Tools — Python round-trip codecs

I want to trace game logic Main Loop and Map — scheduler Combat Overview → Combat System Event Script Opcodes — script VM 3D View and Game Screen — renderer

Key concepts (visual)

Data files talk to each other

map.dat page 1 sets bit 0x80 on event tiles. event.dat triplets reference those cells. attrib.dat picks wall/floor .32 sheets and neighbour links.

Combat is a round loop

Encounters start from event opcode OP_12. See Combat Overview for the mermaid chart and command keys (A/F/S/C/U/B/R/E/V).

Events fire on step

Endianness reminder

Important

MM2 .dat multibyte fields are little-endian on disk (matching Blitz3D editors and our codecs). The 68000 runtime may byte-swap after load — always trace ASM before assuming otherwise.

What's still unknown?

Open Questions tracks unresolved fields and next ASM trace targets.
