DerLangrisser slow down

[CreatureOfNature]

hi, i recently downloaded the derlangrisser version 1.1 rom and applied the translation patch from no life translations. I started playing and i ran into several problems. First off, if i load derlangrisser as my first rom once zsnes opens up, there is no sound and i can't get sound on any other games that i load after ward. i have to load a rom that i have and then load derlangrisser for the sound to work. the next problem i ran into was that after a while into the game (around the part where i enter my name and answering the questions), there is a slowdown of the rom. the frameskip stays at around 15-30 and i can press esc to get back into the GUI without any lag time, it's jsut the rom that slows down. i am using the newest WIP and these are the rom information from the game, the first one is without the patch and the second one is with the patch applied

*edit
oh and also, i can't skip the intro by pressing the start button or it jsut stays at a black screen (i can exit it with the esc button back to the GUI), i ahve to wait through the entire intro with the sword and the lake vilalge, any way to get rid of that?
