This is really cool thank you! Would it be possible in a later revision for a second input and like ZR + D up/down to change the quantity or in furniture cases different colors?
What exactly are you trying to find? I just made an acct to reply but if you look through the NHSE github files there is another list that has a lot more of the Egg Diy codes that you can use too... or do you mean just finding them in the game files themselves...
Here's a list someone uploaded with nearly all of the recipes. Still missing some Egg day ones but I imagine you can just go up and get them I haven't tried.

@Xdqwerty, Osu! Tatakae! Ouendan! is the Japanese version of the game, different settings/characters/songs but otherwise identical mechanics. I played that before I knew about Elite Beat Agents lol. Both fantastic games https://en.wikipedia.org/wiki/Osu!_Tatakae!_Ouendan
