The Chocobos not dancing is most likely an issue with one of the model animations. These models are from the Phoenix Rejuvenation Project. I'll try to track down the original animation and see if that will work with the new models.
All lighting effects are somewhat broken when using the new field textures. If you want the hires lighting effects, uncheck REMOVED GLITCHED under the field textures box before running Bootleg. The game will then the higher quality lighting textures. Unfortunately, the lights will no longer flash and pulse like they do with the old textures. Also, some scenes will have dark blotches. There are still quite a few issues with the updated field textures from the mods FacePalmer, BlackFan and the Field Files Packs. The powers that be informed me that the OpenGL driver will eventually support the lighting effects.
Any issues with music are related to FF7Music. Covarr knows the most about how ff7music works. I've found other problems with it. If you skip the opening movie, the game music doesn't start until Cloud leaves the train platform. Also, sometimes the wrong battle music plays or the battle music plays at the wrong time. FF7Music hasn't received updates in a very long time. I'm not sure if the original author even frequents these forums anymore.
You won't be able to just uninstall the ReTranslation or Menu Overhaul because of the large number of other mods installed. Try installing the Menu Overhaul with ReTranslation and uncheck the Canon Names option. That will at least use the American version of their names. Other than that, you can always change their names in the game or with a program like Black Chocobo.
