Just to clarify, SMB Definitive kinda turns the game into SMB2J physics and all, unless the hacker implements these codes himself I doubt these hacks would be compatible, but perhaps someone can test and see for I was not successful.
Personally though, while I do like a couple of the ideas in the "SMB Tweaked" hack I don't really like most of them...
I like the one that lets you lose your power ups gradually, I like the one where if you hold Jump while bouncing on enemies you bounce higher, I like the one that makes all hidden 1-UP mushrooms work regardless of coins condition, and similarly I kinda like the one where you get a 1-UP if you touch the tip of the Flagpole instead of how SMB2J works with the timer and score counters, but not the rest in the list tbh, but that's just my personal taste.
But it's like I said, this hack pretty much converts the game into SMB2J while "adding" SMB1 levels in the beginning and making worlds A-D accessible without needing 8 stars (you still get stars though, btw) in a way it's a .nes conversion of SMB2J.
