Most fan-made ports and source ports do not include the copyrighted game data themselves to avoid legal issues. Instead, they require the user to provide a legitimate ROM file to extract assets like sprites, levels, and music.

If you need technical help with legally obtained ROMs (e.g., emulation of your own dumped copies), I’m happy to assist with that instead.

If you're having trouble getting the file to work, I can help you or explain how to patch a ROM manually.

: While ROM hacking can be seen as a form of game preservation, it also poses ethical questions about the rights of creators and the value of their work. Some argue that ROM hacking can help keep classic games alive, especially if they are no longer officially supported or available.
