The meter that goes up after beating stages that once full guarantees a golden powerstone as reward from your next win.
I've been looking into it aswell and figured out how to change it so it's always full, I'm not sure on how to share it so it's easy to edit though since I'm a newbie to GG
If someone does know how to simplify the process then feel free to share it
100% Bonus Meter / Always Golden Stone Rewards
The Bonus Meter has 11 parts(not counting the 0)
1. Byte Search the number your bonus meter progression is currently on (0,1,2,3,4,5,6,7,8,9,10,11)
2. Finish a stage succesfully and search the number it is on now.
3. Repeat step 2 until you feel like you have the right number.
4. Edit the number and put it on 11 (freeze it to keep it stuck on full)
5. Go win stages and enjoy getting golden powerstones every time ?
The bonus meter will look like it's not 100% after you change it to 11 but after you complete a stage it'll fix itself to display the full meter (either way once you put it on 11 it counts as a full bar regardless)
