Hey man, the original author of the codes for High Speed Processing, Gauge animation + PKMN Center animation cut had made an improved version of High Speed Processing that I have been using for days now. Virtually 100% stable, you should completely replace the code for all supported HGSS roms honestly. It doesn't break cut scenes or speed up the starting screen, it only makes battles and party interactions speed up (and again, way more stable)

(from that same post you might consider adding "No Recharge From Attacks" and "Fly Animation Cut")
EDIT: Fly Animation Cut causes black screen when choosing saved game
Code:
::No Recharge From Attacks
:::E.g. Hyper Beam, Hydro Cannon can be used 2 times or more in a row without a recharge
