I'm new to rom hacking. I've been able to successfully apply .asm patches using Maxkas on a Mac (ground pound), but it seems like some of the patches on this site either don't do anything or crash my emulator (wall kick). Is that a problem with the patch, or am I doing something wrong? In case you ask, I did double check if I needed to use 'xkas' or 'asar'.
I would like to use a customized version of the Yoshi Player Patch v1.11. I want the player to start as Mario in the first level but play as Yoshi for the rest of the game, and I want to add a couple Yoshi mechanics. Is this possible, given the layout of the rom's code (maybe replacing the Luigi player with Yoshi and forcing the player to use player 1 in level 1 and player 2 in levels 2+)? Are there resources/tutorials/tools specifically for writing patches?
