I'm wondering if this entire procedure is being done on clean ROMs or AP patched ones?
EDIT: Nvm. Did it on an AP patched version and got as far as the summary freeze, so I know it's done in the AP patched versions. Now to iron out the mistakes. Also, I've found that if you want to make any other edits (eg: TM modding) to arm9.bin, you have to do it before you insert it in the insertion process. Otherwise you get some error saying that it's too small or something or other. Because of it I had to do re-insertion two different times. Guessing I did something wrong the second time cause it freezes at the summary now.
And if I haven't said it before, THIS is AMAZING! Good job @MeroMero !
EDIT2: So, before I added in the Fairy-Type itself, I changed TM19 to Extrasensory. I had already changed its type to Fairy via hex and this is what shows in the bag:
Yes, yes. It's Moonblast, replacing Extrasensory. It's also text editing. I even added Play Rough in place of Horn Attack:
The thing is, as you can see, the type image isn't displayed. The summary freeze fix has been properly implemented over here, so I guess this is just one more thing to figure out. Just wanted to let you know that this is how it was.
