GrayShadow's 'Giving Gogo Magic' code

No this does not effect anything with the sword tech speed, just the sword tech learning routine. Patching it directly how it is will effect some other stuff though as mentioned, mainly giving Mog a dance skill learned at recruitment, and adjusting something in Celes's natural spell list, just moves a spell. Oh, and of course giving Relm natural magic like Terra and Celes. Besides that the main thing is it takes HatZen's Resilient Morph patch into account. So that will need to be removed from this file if not being used, I think. The patch itself relocates sram addresses and utilizes the unused Sword Tech naming space in order to do what all it does. GrayShadow's explains it better there in the intro section of the file.

Aside from that just be sure to change the instances of 0D to 0E, in order for it to work for Umaro's range instead of Gogo. In other words it does a bit more than just give the magic to Gogo, so be sure to edit it (carefully) to your liking first before patching.
