Relm's Sketch edit

The only issue is newbies don't know how to apply ASM coding.

And here's a youtube link for how to apply ASM coding to patch ROM's with it. https://www.youtube.com/watch?v=Eu8Jr1-QRY8

I watch the youtube, but some corruption happened to the rom. 

I 1st copy & paste the patch code onto a notepad, and then turn the "txt" into "asm". 

I did the youtube 1st method, and the game work. However, once I enter a fight, the screen turn black and nothing move. What went wrong?
