@SlurpingPus @pieland Glad you noticed! It is a little tip of the hat. 😃

The non-packaged name of the save file that's included with the ROM is:
qr_paint_FLOWER_DOGCOW_SKULL.sav (it gets renamed during the packaging stage to just qr_paint.sav)

@PiraHxCx @sic_semper_tyrannis There are a lot more Game Boy releases than shown on MobyGames. I don't know if the site is limited to just physical carts, but even if that is the case then the actual number is more like 269 instead of 42 since 2020

@PiraHxCx Here's a brief tour of the Game Boy relevant databases...

DMGPage has some of the most complete data (i think?) for the Game Boy. The format is easier for me to work with.
https://dmgpage.com/homebrew-releases/

There is a japanese page that tracks some GB releases:
https://geemuboi.web.fc2.com/misc/new-releases.htm

Game Brew Almanac tracking has more platforms. The format is less structured.
https://www.videogamesage.com/forums/topic/1050-vgs-homebrew-almanac/

And Homebrews Connexion that also has more platforms:
https://homebrews.retro-gc.fr/

@sic_semper_tyrannis Oh yeah, at least in terms of homebrew being made GB is likely 10x GBA (whether cart or rom)

@hitstun @pieland Compression for PNG (or BMP/GIF) output is possible. As long as it remains browser compatible. Not yet sure if I'll implement it.

But it's a Jevon's paradox situation where I'd just use that to fit more image data in the same size QRCode (ideally gb camera resolution and 2bpp instead of 1bpp) instead of reducing the QR size.
