mstan/SonicTheHedgehogSMSRecomp — reverse-engineered prompt

I want this repo turned into a simple Windows desktop build of Sonic the Hedgehog for Sega Master System that runs from my own legally dumped ROM, not anything bundled in the repo. Please use the existing setup here to regenerate the game code from the ROM and compile a native executable, then make sure I can launch it by pointing at the ROM file and optionally choosing a bigger window size like 3x.

It should feel straightforward for a normal person to use. If the ROM is missing or it is the wrong version, show a clear message and stop. Keep the keyboard controls working as expected, arrow keys for movement, Z and X for buttons, Enter for pause, Esc to quit. If there is already a release style zip flow, keep that usable too.

Please wire up whatever is needed so the build works cleanly on Windows with the sibling engine checkout this project expects, and add brief setup notes if anything important is missing. Look up current docs online if you need to.
