Metal Gear Solid Portable Ops

[Cottommy]

Hey guys, new to this forum and this emulator, and I'm having issues running Metal Gear Solid: Portable Ops in a satisfactory state.
I'm looking for tricks, tips or fixes that anyone may know on how to get this game working the right way.
So, the issues so far are:

-Sound: It only seems to play sound effects, but no music. Unsure whether or not there are also some sound effects missing

-Video: There's a few videos and cutscenes that play, but there's no opening cinematic after the konami and kojima productions logo. In the first few minutes of the game, the same thing seems to happen, and I can just press start to get past it. However, being a Metal Gear Solid game, I can only assume that a lot of the cutscenes are quite important.

Graphics: There seem to be a lot of clipping with objects, and many textures won't load unless I'm looking at them on the correct angle:


I apologize for posting so much, but being new to this emulator I'm finding it hard to know what settings are best for emulation, or, if there are any plugins, which ones to use.
Any help is greatly appreciated.
