So I've run into the softlock that occurs in the room that is listed in the title and saved after leaving the room with 2 sonic switches hit, i've been wondering if soneone could help me undo that softlock by altering my save file so that those switches were never hit. If anyone could do that, that would be greatly appreciated.

Oh and if possible I'd like my pickups and scans to be intact.

There currently isn't a tool that allows you to edit save files. If you're looking to get a save file with everything scanned, there's a 100% Save File that can do that for you.

This is a casual playthrough, and I am NOT gonna fight the boost guardian again, so that means I'll never get to beat the game. I just want my save file to be not softlocked, and I'd prefer any pickups I collected to still be collected.
