JoeTE | Sonic Adventure DX (2004 PC Version) - Metal Sonic in Speed Highway @JoeTEStrikesBack | Uploaded September 2015 | Updated October 2024, 3 hours ago.
I wanted to test out recording the old PC Version of Sonic Adventure DX, so I made this video. I chose to play as Metal Sonic in Speed Highway as a nod to a certain Generations mod of mine.

NOTE: The ability to play as Metal Sonic in this game is NOT a hack or mod. You unlock Metal Sonic as a playable character by getting all 130 Emblems.

For a bit of backstory, I had the urge to replay Sonic Adventure DX last Sunday. So I re-installed the old PC version (which I actually own, just like Heroes,) then got things to look (and control) better using MainMemory's SADX Mod Loader and Morph's SADX Fixed Edition Mod (along with his Xinput fix mod.)

Within about 3 days, I got all 130 emblems, and beat all of the missions in Mission Mode. This game was a lot easier (and quicker) to 100% then I remembered.
