Tip: If you want to remove patches from your ROM, it is best to either use the restore function, or port everything to a clean ROM.

Patching Tutorial Video (also covers headered vs. headerless)

So idol pointed out that there were tons of technical-related sticky threads, and not enough activity to warrant all of em, so I'm just gonna combine everything I do into here from now on.

Some background on me/technical Yoshi stuff:

Back in 2014 I took on a disassembly of this game with Lexie. While that is now 100% complete, it was only the beginning. There is still today tons of stuff being figured out, and the disassembly is constantly being worked on - how??? I just said it was done, right? Well, it is done, but very little of it was documented. There's a difference between it being done and assembling to clean ROM, vs. commenting the code, naming labels and variables, etc. There's a good amount done on that front but nowhere near 100%. So under this new metric, it's not anywhere close to "done".

Along with the disassembly text itself are also the RAM map, SRAM map, ROM map, hexedit map, and my companion technical wiki for explaining stuff in a broader picture than can be done in code comments. These all go hand-in-hand and each one being more complete helps out for the other.

Then separately from all that are just the patches, which change game behavior in some fashion. Take a look at the patches section linked above for information on these.
only one post? that doesn't make it a megathread

A. It's called a "megathread" because it's meant to be an all-purpose thread for information related to the YI disassembly; the fact that it doesn't have many replies (yet!) is irrelevant.

B. I don't think that the second part of your post is super relevant either..also, TMI?

Admittedly, I kind of forgot about this thread; thanks for reminding me about it at least

The handomest people in the world are ones who follow my Twitch
This thread is basically dead because Raiden decided to step down from the site and rom hacking, and there hasn't been so much progress on the disassembly documentation. Plus, there aren't other "big" asmers trying to go insane in ASMing YI. On the other hand, there was supossed to be the Tweak Map, focusing on hex edits and stuff to tweak/customize a Yoshi's Island romhack (basically all ASM info from FAQ and Offsets threads but organized), where some people was working on (me being one of them) but again, it's most likely to not be released because the lack of interest on it (and YI hacking in general)

In the meantime though, everything related to general YI ASM can be discussed here... I guess
