Readme File: ------------------------------------------ Sonic Adventure 2 (Single) [NTSC-U] ------------------------------------------ Dreamcast Resurrection - 2009 (since 2008) Check for more releases at these forums: snesorama.us (all releases) segahub.org (recent releases) dreamcast-talk.com (recent releases) ------------------------------------------- Ripped: Internet feature, japanese voices. Downsampled: Sound monoized (including video's), FMV downsampled. Source: GD dump and Echelon's release.

As I promised, here is my single disc release of Sonic Adventure 2. It was much harder to do this than I thought (cost me one full day of work! The Leprechaun Origins. ), but at least the result got nice. It's much superior than Echelon's version, I hope you like it. I had my first problem when monoizing the sound. The music had something different on its header so Darkfalz's loop calculator found wrong loop data.

It means that when repeating, music behaviour was terrible and took playing to the wrong place. After some research, I found no other tool capable of getting the loop samples that I needed. So after some more research I found a description about ADX header, so I could write my own tool to extract loop data. Fortunately, the data I took was correct, so music got perfect.

First problem solved. Note that I used a high quality decoder, so monoized music has high quality. Echelon guys used a decoder that made low quality output with 32khz input (frequency of most songs of this game), so my release has better mono songs. Echelon guys also decided to keep some songs stereo (sacrificing video quality), but I monoized all. There were some Chao songs that were mono already, so I let them untouched.

Hard part done? When I started working on videos I noticed another problem. Video had 2 audio streams: first one with japanese audio and second one with english audio. At first look there was no problem, but I had no idea of how multiplexing things back after downsampling. Dreamcast Movie Maker (that I used as multiplexer) was only capable of multiplexing one audio stream.
