The upcoming "Nintendo Switch 2 Edition" version of Tears of the Kingdom introduces - among other things - a new feature that lets users share their Autobuild creations as QR codes.

QR coodes are used with the Nintendo Online mobile app.

During a Treehouse Live livestream, one of these QR codes was shown. This could be decoded to the URL https://s.nintendo.com/dd1/znca/game/5080866659500032?path=%2Ftotk%2Fschema-stones%2Ff17f67a7-31b2-428f-bac1-13d3a1641125%2Fadd.

The dd1 here indicates that this is on Nintendo's development/staging environment, so presubably this is the reason why the link 404's if you don't have access to this.

Unclear at this stage as to whether more information can be gleaned about Autobuild schema without requiring the app. Just wanted to document this for now so I can return to it.

General tips

• For repeated expensive drawing options, such as drawing a rotated sprite or a large amount of text, it's a good idea to cache the result to an image once and draw that repeatedly instead.
• Audio formats in order of decode speed, fastest to slowest: 16-bit pcm wav, 8-bit pcm wav, adpcm, mp3.
• The Playdate's audio sample rate is 44100, but if you're experiencing lag when playing audio at that rate, you can try halving the rate to 22050.

C tips

• The Playdate has a weak CPU but a comparatively generous amount of memory. Favour memory-based optimisation techniques, such as lookup tables.
• Where possible, move branch statements outside of loops, even if it means duplicating the code for the loop. (probably applies to Lua too?)
• If you need to parse a binary file, use playdate->file->seek to jump to the parts you need and playdate->file->read to only read the data you want. Try to avoid memcpy-ing the whole file to memory in one go.
• If you're blitting to the frame buffer and need to ap
