Item cheats for myboy?

When looking at that code, I think you need to replace the three X's at the end with certain numbers according to the item wanted. That code should work as long as you replace the X's with certain number and letters according to what items you'd like.

That code allows you to buy any item you'd like.

These are the items and TMs/HMs you can buy after replacing the X's with these numbers and letter combinations:
