Context (skip if desired)
When I was a kid, my first experience with Sonic was the Sonic & Knuckles Collection for Windows. I had no knowledge of the fiasco with the music of Sonic 3, and rarely made it past Marble Garden Zone anyway, so to me, a kid raised on MS-DOS shareware, the collection was just another, fun, 2D platformer with punchy Sound Blaster support.
Fast forward a few years, I pick up Sonic Adventure DX for my low end E-Machines, and once again, I wasn't aware of the porting downgrades from the Dreamcast version. The music volume did overpower the voices, and I purposefully played at 480p to avoid seeing the glitched subtitle bar, but as far as I was concerned, it was a sequel to Sonic 3 that, due to the hub worlds, kept true to the title - it was now an ADVENTURE.
Over 10 years later, I'm now an adult, and decide to buy Sonic Adventure 2 Battle on Steam to see if it was as good as everyone else my age remembers it being. I play through the first few stages, but lose interest as I soon realize there aren't any hubs anymore, Tail's is trapped inside his mech, and, it just wasn't what I was expecting as the next part of the series at that point. I still wasn't aware of the graphics glitches, but everything did look visually unappealing and lifeless to me anyway, like something was... wrong, even though I didn't know better.
But I've recently been watching videos showing just how butchered and downgraded the ports of SA1 and SA2 were to the Dreamcast originals, and my interest re-sparked. I've been emulating SA1 on my PS Classic and rather enjoying the added sense of atmosphere to the lighting, as well as the PROPERLY balanced audio levels. I can now actually follow along with the cutscenes without paying too much attention or blowing out my speakers.
When it came to SA2, however... I game overed at City Escape and gave up. I kept stopping abruptly, over-steering into walls, falling down seemingly easy pits, and could never land on a grind rail no matter how much I tried. What's weird is I don't remember it being this hard on the Steam version.
But I don't want to play any further into the steam version, as I now know just how many layering issues, visual bugs, missing audio cues, and once again, improperly balanced audio in the cutscenes, I'll have to put up with. I can't make sense of the story, for example, when the characters are talking about Earth on the Ark, yet the new Earth texture is too small to show up through the window they're looking through.
The Question (Tl;dr)
What is the most complete, hassle-free way to experience Sonic Adventure 2 with BOTH correctly tuned cutscenes, as well as controls that aren't infuriatingly twitchy? Does such a thing exist?
