This is a living document to let you know what is planned for GameCube/Xbox in the future by myself. There is no ETA on this stuff.
Patch all quests to be completely safe as download quests and never mess with story progress
Introduce a trade-in quest which allows variable Love Heart, Safety Heart, Virus Armor: Lafuteria, hit% enemy / quest weapons, and the ability to trade common weapons to an equivalent of a different tier
If I think of anything further, I will add it to the above.
