Arrow Flash MD+
A downloadable mod
Arrow Flash MD+ is an enhanced version of Arrow Flash for the Sega Mega Drive / Genesis. This project adds MD+ audio support, including enhanced PCM playback, while preserving the original game’s gameplay and identity.
It’s designed for use with MD+-compatible hardware or emulators.

This download contains a patch only. No original game ROM is included. To play, apply the included patch to the specified original Arrow Flash ROM revision. Please read the included README for the required ROM checksum, patching instructions, and compatibility notes. The game can also run without MD+ support.
However, the normal audio fallback has a known issue:
the music may slow down. For the intended experience, use MD+-compatible hardware or emulation.
This project was developed with AI-assisted tools. The creative direction, technical decisions, testing, and final validation were carried out by the project author.
Feedback and bug reports are welcome.
