The PC version hack is where I got the idea and I do also want to implement the Sub tank, sub weapons, etc..but I'm pretty sure that's way out of my league.
Edit:
http://www.youtube.com/watch?v=UsCrxcJAF7o - Another Megaman X3 video. NOP'd out a function so you can always play as Zero even when he does die. With that, I think I found a whole slew of text related things and have them somewhat labeled. I'll probably get to that later, but for right now it's in my log.
Edit 2:
http://www.youtube.com/watch?v=1su-71VXDSc - Once again another. I had to re-do just a little bit of code for Zero's portrait so it wouldn't ever call the static screen when you switch to him. With that, you can now play as him ALWAYS even if he dies, but you can't switch to him during scenes you shouldn't be able to, AKA Boss fights or the introduction level.
