I'm interested in fixing those. Thanks for the report! Please let me know if you run into anything else. I'm getting an update ready that will add even more Dreamcast objects (Final Egg cylinders with a plasma effect and rotating stationary lights! Yay!), some effects (like the cloud layers in Red Mountain), an optional HD update to all ingame UI that can be scaled, and a few other things. I hope to fix the missions in that update too. As for the Sound Overhaul mod, I feel at this point that it's a failed experiment. The method I used to get the sounds ripped from the Dreamcast version just isn't good enough, and I can tell that some sounds are produced with defects that weren't there in SA1, or are just completely broken. It's almost like the only viable solution to rip them properly is through the sound test, which is super inefficient and will take ages, not to mention some sounds won't have the necessary effect applied to them in the sound test. I'm also starting to suspect that the game has trouble handling sounds with a sampling rate other than 22050 Hz. The audio has suffered in this game just as badly as the graphics/lighting in the ports, and making it sound like the Dreamcast version is a project of a magnitude similar to, if not bigger than, all the DC mods combined. It will take months of work, and it will require many code-based fixes and imitation of postprocessing for many sounds. And even if you do that, it still won't be the same. The only way to make it sound exactly like SA1 is to implement native Dreamcast audio so that the game actually uses the MLT sound banks. Sadly this is way outside my area of expertise (though not impossible for other people perhaps), so I'll look into redoing the sounds manually. Maybe just a few of them, in cases where the difference is very evident, like when a sound is missing, or the character voice clips.
