Hey, I've been watching a lot of your videos on youtube, keep up the good work!
I've tried to install optifine following your tutorial but I had these results:
Stage 1 only (didn't touch the minecraft.jar)
Launched Voltz from the techniclauncher, it loads fine, I can change all the optifine settings, BUT I can't load multiplayer or single player games.
Stage 1 and stage 2 (modified both jar files)
Voltz won't load at all from the technic launcher, the launcher just idles there with it saying "launching..." but nothing happens.
