Yuna Remix - Bonus mode and Debug mode 2026-01-05.01

This is a patch for Ginga Ojousama Densetsu Yuna Remix on Saturn.

This game has two hidden features:

• Bonus mode: Contains a movie, image, and sound test menu.
• Debug mode: Contains a cutscene viewer, a map test, a music test, and a battle test.

Bonus mode can be accessed by using the special Hudson SBOM Joycard controller. This patch makes it available without that peripheral - just go to the Options menu.

Debug mode can't normally be accessed. This patch launches it instead of the normal game.

Apply the patch with Delta Patcher:
