Sonic Adventure

Sonic Adventure originally debuted on the Sega Dreamcast, and I owned it not too long after it was released. It was a great game, but also too difficult for me back then. I don’t think I ever completed it, and instead started playing Sonic Adventure 2 when that was released, and enjoyed it so much more.

Sonic Adventure was later released on the GameCube and titled, “Sonic Adventure DX: Director’s Cut.” This version had higher-resolution textures and more detailed character models. However, it was not the version I initially played, and thus didn’t look the way I was familiar with, and many other fans of the game were not happy with the changes. Likewise, the game was also ported from the GameCube to the PC. The original PC release (not the Steam one) was ported to the Xbox 360 and PlayStation 3. Then the Xbox 360 version was ported back to the PC for the Steam release.

I was unhappy with how the Steam version looked, and the lack of widescreen support. So, I found SADX Mod Installer. This mod is a collection of various mods that restore the original Dreamcast lighting, characters, and other changes in the PC release. It makes the Steam version the original PC release, applies changes, and restore Steam functionality, such as achievements. Simply install it and check off the mods you want and play.

I’m playing with the following mods, which is all of them (except the Frame Rate Limiter since I’ve found it actually makes cutscenes choppy every few seconds for some reason).

Also, after recoding the first part, I noticed the new sound effects were too loud. After some research, I found a fix which is to enable the “Logarithmic Sound Volume” setting in the Sound Overhaul 2 mod. The hint says it should be used with DSOAL. If you browse the mod folder, and read the changelog, it indicates, “Starting with version 0.8532 (October 22, 2019) Sound Overhaul 2 has an option to enable logarithic volume controls. This option makes sound effects louder and is technically more “correct” than default ingame volume adjustment. However, it does not adjust the volume of 3D sounds, which will be too quiet in comparison. To fix this, use a DirectSound wrapper called DSOAL (see link above), which will fix volume adjustment for 3D sounds.”

Since upgrading to Sound Overhaul 3, the audio in the game is louder and supposedly fixes the volume of 3D sounds, but it is still required to have DirectSound wrapper installed, which seems to differ from the one in version 2, and can be found via a link in the changelog of the mod.

Feel free to also check out the playthrough by SlimKirby. He managed the difficult task of getting all the emblems. He also played using the DX GameCube version, so there will be some differences.


The story follows Sonic, Tails, Knuckles, Amy, Big, E-102 γ (Gamma), and ?. You play as each character and view their perspective of the overall story of Dr. Robotnik (Eggman) bringing back an ancient creature, Chaos.

This ancient water creature absorbs chaos emeralds to gain its power. Sonic and Dr. Robotnik battle for the chaos emeralds. But, as Chaos grows from each emerald, the town (Station Square) becomes in danger.

During Sonic’s story, you are mostly battling Eggman and Chaos. Sonic chases down Eggman who keeps stealing the Chaos Emeralds to feed to chaos. After defeating Chaos, Sonic battles Eggman one last time and his story ends.

During Tails’ story, the tone is much different. Tails looks up to Sonic like a role model, and most of his stages consist of racing Sonic to the finish. Tails becomes separated from Sonic at one point and has a memory of them together, but they quickly meet back up. At the end, Tails gets his time to shine as he saves Station Square from Eggman.


Each stage is divided into three sections, almost like acts, and has different music, and sometimes different mechanics. Some stages, such as Casinopolis, have different mechanics entirely, requiring you to collect coins and deposit them in a bank to finish the stage.

Each character controls differently. However, the controls tend to be a bit difficult at times, and the camera is pretty bad. It will turn unexpectedly when you don’t want it to. And even in free look mode, it’s still bad.

Sonic moves fast and can spin dash to get across the field quicker, but he also gets a power-up to dash through lines of rings. Additionally, Sonic has a homing attack to attack enemies.

Tails mostly flies and his stages revolve around racing sonic to the exit. The levels are quick since you can skip most of it by flying.

There is also a Chao side gameplay where you can grow and race Chaos. Give your Chao animals to power up the status, or purchase upgrades from the shop using rings you’ve collected.

The unique thing about the original Dreamcast was the memory card, the VMU. It was a small portable game system, and Sonic Adventure took advantage of this. Your Chao was saved on the VMU and when not playing Sonic Adventure, you could play Chao Adventure. There were various areas to adventure through, items and characters to find that boosted your stats, and play a matching game. If you had a friend with a VMU, you could battle and mate Chaos. I effectively maxed out my Chao this way!

There are 130 emblems in the game. In order to get all of them, you’ll need to complete each level three times. You get an emblem for completing the level the first time, another for beating it with at least 50 rings, and another for completing it within the time limit. There are also 12 emblems in the overworld, 10 in minigames, 5 in Chao races, and 7 after each character’s credit sequence.


For a game that came out in the late 90s, the graphics are quite impressive on modern hardware with upscaled graphics, HD textures, and widescreen resolution. Since I am using mods to achieve this, including restoring the better lighting and textures of the original Dreamcast version, I personally think the graphics look amazing.

The character models also look good, even the new ones for the DX release (not used in my playthrough). That being said, the character animation in cutscenes is quite funny. The way some of the characters move their mouth is hilarious.

Sound / Music

The music in the Sonic series is one of my top favorites. Each character has their own theme, which is not only catchy, but also a quality song. The music in the stages is also really good and sticks with you, some stages more than others, but overall a solid soundtrack.

Sound effects fit the game, as well as the character voices. Actually, the voices are quite hilarious at times, but that is the charm of the game! “OH NO!” – Knuckles 👊
