Add-ons are pretty cool. Kinda reminded me of this "backport" of SMA2, called Super Mario World DX:
They even got the Status Screen, which is very nice!
it's always weird seeing that pop up, have seen it on youtube a few times too. Sometimes I wish I could erase it entirely though, because I've always felt guilty at how little of the actual code I did for it. For the most part it's just smw central asm patches assembled together on a vanilla rom + all the needed bug testing, I still haven't even finished the last thing I promised I would.
But anyways, I wanted to say I really love how far this project has come since it first started, and the seperate Luigi mode is a really nice way to replay All Stars (and I guess World, too). The last thing that feels missing is his little flutter kick that he gets in sma2 and smb2, his actual movement feels very on point to what you'd expect.
