Congrats - Links Awakening is truly a masterpiece and yes, they really worked hard to get a whole Zelda onto the GB.
I’ve never played a 3D Zelda before so I am looking forward to OoT
In case you go the emulation route and don't use the version on Nintendo Switch Online (or a virtual console version on older Nintendo consoles), you should also take a look at Ship Of Harkinian. They decompiled OoT and ported it to run natively on several platforms. In contrast to other versions, you can play it in wide-screen, with unlocked framerate (instead of 14-20fps of the original) and you can also enable several QoL features (everything optional). You only need to provide a ROM file, but in case you plan to go the emulation route, you'd need that anyways...
