This is still in very early testing, so be prepared for some odd behaviour and possible random crashes.
Welcome to the Super Metroid and A Link to the Past crossover item randomizer.
This randomizer mixes Super Metroid and A Link to the Past together into one experience and will randomize both games items to any location in either game creating a new kind of multi-game challenge. The goal is to kill both Ganon and Mother Brain and then finish either game.
Travel between the two game can be done by using certain doors and entrances in either game, a list of those can be found in the document linked below.
As of version 9, an easier difficulty settings for Super Metroid (Casual) is now available that's more in line with the "no-glitches" A Link to the Past logic.
Huge credits to the ALttP Randomizer team for much of the tools used for the randomization and for the ALttP randomization patches and logic.
