Open Doors: Super Metroid half-hack where all of the doors are open. If that's not enough, there are additional game mechanic changes (as of version 1.4):
- Gates are removed.
- Super and power bomb blocks are replaced by shot blocks.
- Shinesparks/blue suit can go horizontally through shot blocks.
- Bomb, crumble, and speed blocks are shootable.
- Screw attack can go through all of the above.
If that's too much, there's also a "Doors Only" option where the only game mechanic change is the open doors (and also Zebes starts out awake with morph ball available). This hack offers different routing options and speedrunning strats both with and without the Doors Only option.

Credit ShinyZeni with the idea, and InsaneFirebat for multiple resources including the Map and True Completion verification built-in (minus door verification since they're already all open!) I also received help from several others: PJBoy for the disassembly, kara for the endgame reduce flashing patches, NobodyNada and Sniq for understanding of glitches so I could fix the yapping maw crash, Avalanche for patching out the gates, Chabo for eternal spikesuit (that patch isn't built in, but it is compatible and was useful for testing!) I'm sure there are others as well; thank you!

I expect more updates will be coming in the future. I'd like to make a few room adjustments to facilitate longer shinesparks, and perhaps a few easter eggs too.
