mstan/EmeraldRecomp — reverse-engineered prompt

Build me an early but playable Windows desktop version of Pokémon Emerald using the code in this repo. I want it to run from my own legally dumped USA Emerald ROM, not ship any game files, and it should verify the ROM is the right one before launching. When I open it, it should prompt me for the ROM the first time, remember that path, boot through the normal intro, and get into real gameplay.

Please keep the current idea where missing code paths can run in an interpreter first, then get compiled and cached so the game gets faster and more native the more it is played across future launches. I also want the basic keyboard controls working for the GBA buttons, plus save states on function keys.

It is fine if this is still an early bring up and not a perfect finished port, but it should build cleanly and be usable. If this repo depends on a sibling engine project or current setup steps, look up the docs and wire it together correctly.
