Added a description to each hack. But I'm still not sure about YI.

Removed hacks for Battle Grand Prix, Neugier and Bubsy II. Refined hack for Home Alone so it won't be applied for Home Alone 2.
Finally fixed the most annoying bug ever. ZSNES will no longer jump back into the GUI randomly if you press F2 / F4 or some other buttons repeatedly. Now you will never bother me again you piece of shit. Special thanks to Dan for the clues on how to recreate it.

jbo_85	e06d977329	Removed hacks for Battle Grand Prix, Neugier and Bubsy II. Refined hack for Home Alone so it won't be applied for Home Alone 2.	2006-05-07 00:07:19 +00:00
jbo_85	800eb94424	Finally fixed the most annoying bug ever. ZSNES will no longer jump back into the GUI randomly if you press F2 / F4 or some other buttons repeatedly. Now you will never bother me again you piece of shit. Special thanks to Dan for the clues on how to recreate it.	2006-05-06 22:41:04 +00:00
