What's Libnes?
If it's a library, then no, I did not use that. It's 100% made in Assembly.
If it's an emulator, then I cannot guarantee the game running on it. This game was extensively tested on many hardware revisions without issue, but is known to fail on several older, less quality emulators. Please use MESEN if you want to play on an emulator. If you want support in a specific emulator, contact said emulator's developers instead :)
