I have a huge-mega mod bg2 game. (Not bgt)
I played around with the neverending journey mod, disliked it and uninstalled it. After that, my main menu has no theme music for soa or tob portions. All other sounds and musics work fine in game, just the main menu is silent. Neverending journey had a custom main menu and music, so I think that is the culprit.
My current mega mod installation is like my prized child, with a lot of mods,all bugs hand-edited over three years, (Scs+improved anvil hybrid, and with other mega quest mods, too!) plus with tons of customisations, extra spells, items, dialogue etc. all hand-made by me, I even changed gui pieces with iwd ones, and got some sound files from nwn games on my own. I know my way around dltcep, I can edit spells, items, areas, creatures, even scripts. I fixed crashes and mod incompatibilites on my own. It seems I spend more time editing and modding than playing the game, but I like it.
I couldn't find a solution to this problem, however. What file should I edit to fix this issue of no-music in main menu? 2da files of music etc. I have little knowledge about. I check musiclists of unmodded bg2 game and it looks the same as of my own, I am at a loss. Any info as where to look and what to do will be appreciated.
