Need Some Help

So, hmm, I'm missing something with my own attempts at using the xkas utility here as well.

Yes you are missing something. xkas is a console application and should be used as one: https://youtu.be/4A13pN9_s7c

My explanation is clear: easiest way to do this is moving in same directory as the patch and ROM and xkas, with the "cd" command and then type "xkas sketch.asm romname.smc". You bat file is to assemble test.asm to test.smc, it won't work with anything else. I'm not going to give a command prompt class each time I post code.

Also, I made a patch 12 hours later so he just have to hex edit the spell ID. I can't be more helpful than this.

Yeah I was confused at first, too, but then I watched that video and it made more sense. But you've been really helpful.

I applied the patch without editing anything and there was some weird stuff like fight command doing nothing, for example with minor graphical glitches. And then when it went to the scene with Terra in the Magitek armor killing soldiers the emulator crashed.

But I went to Sketch in the hex edit by using the guide on Assassin17's site (http://assassin17.brinkster.net/code2i.txt) and went to this offset "C2/1520: 20 8A 29" which the guide says is where Sketch loads command data / etc. and tried editing it to A8 (which is the spell I want Sketch to use) and that didn't work. So I'm going to have to toy with it more.
