In the exe at offset 0x9E68C4, extract 0x80000 bytes (512kb).
The ROM as-is contains an incorrect checksum (0x1C27) and will need to be corrected (to 0x876C) before the ROM can be playable.
I found this Python script as a simple and easy solution to do that: https://github.com/mrhappyasthma/Sega-Genesis-Checksum-Utility

In the exe at offset 0x7F29B3, extract 0x20000 bytes (128kb).
No other modifications are necessary, the ROM is playable as-is.
I also noticed that there are VGMs within the exe, but I haven't looked into extracting those as of yet. I'm sure it's as simple as finding the right offsets and lengths to extract though.
