@wiley87What version of the game do you have, 1998 or 2012?
For music enhancements, search on the forums for Anxious Heart.
For graphical enhancements, search on the forums for Universal Model Installer and Ozmy's FFVII Field Pack.
Whatever else you want you will need to search and read for yourself:
http://forums.qhimm.com/index.php?topic=12503.0 --- Every mod can be installed separately from Bootleg and usually come with instructions on how to do so. If you are going to do the manual installs, it's not recommended to use Bootleg at all. Bootleg does have a Minimal Preset that might be for you. Just make sure to change the game mode to Hardcore before you run it.
@nikolazYou are running on Intel HD Graphics, which runs poorly and isn't supported for these mods. Does your laptop have a GPU?
Your battle menu looks that way because you have enabled Break Limit 9999 for both Menu Overhaul and Bootloader Configure. Leave it unchecked inside Bootloader Configure.
@WSabeyI am really sorry for not responding to you. To be honest, I can't replicate your problem. The only thing else I can offer is to try running with vsync turned off and refresh rate set to 59. Test them separately.
