Still working on tech changes, and I've run into a stumbling block.
My plan of attack is to relocate tech targeting (because the extra tech names run into it), weapon data (tech targeting partly overwrites its old location), and the tech grouping data Vehek posted earlier.
Part of the data following it relates to the battle gauge chosen when the eighth character attacks (probably all, but I figured this out after a glitch with the eighth character's battle gauge).
I'm not sure where the battle gauge is chosen, or how to move that value so I can insert another tech group.
