Don't apologise for making a perfectly legitimate suggestion. I was only trying to encourage you (and many others who are thinking similar questions) to go find the tutorial I wrote to add the Trainer Facing Fix, and try to implement it yourself.
If you try and succeed, you learned the basics of inserting ASM, if you tried and failed, I will offer assistance, but if you don't try at all, I won't help you.
I got no such help when I was learning to ASM hack, and I had to learn everything for myself. In many ways, the best way to learn it is to back up your hack and just try until you get it right!
