Overworld Randomizer

This is a overworld randomizer for The Legend of Zelda: A Link to the Past for the SNES based on the Door Randomizer found at Aerinon's Github Project. See https://alttpr.com/ for more details on the normal randomizer.

Known Issues

(Updated 2021-04-21)

If you want to playtest this, know these things:

• Camera unlocking issues, which opens up the possibility of a hardlock. The workaround is to move Link around until the camera locks in place. DO NOT try to transition where there is a visible line.
• Big Red Bomb may require bomb duping as ledge drops may be in the way of your path to the Pyramid Fairy crack
• Do NOT grab the Frogsmith until you have seen the Blacksmith location. Doing so may prevent you from continuing in your save file.
• Inverted regions/rules/logic is NOT implemented yet. Generation should fail 100%.
• If you fake flipper, beware of transitioning south. You could end up at the top of the waterfall in the southeast of either world. If you mistakenly drop down, it is important to NOT make any other movements and S+Q immediately or there will be a hardlock. Falling from the waterfall is avoidable but it is super easy to do as it is super close the the transition.

Known bugs:

• When generating, there is a message about one location that remains unfilled. You will find a Nothing item at that location. This is known and being looked at.
• There may be an issue with progression being front-loaded in the seed in some scenarios, due to an unsophisticated shuffle algorithm that could make varying-sized parts of each world unreachable
• Some rare instances of vanilla transitions occur when they should not, you can tell when this bug occurs because it doesn't re-center you within the gap. These cases are seemingly unreproducable, so you can re-navigate to see where it was supposed to lead. Video proof of these occurances are helpful.
