In the disc's root/Stream:
aLeaderStream aOpeningStream BigStream
These seem to be the main audio/video files. I've tried "importing raw" the aOpeningStream file into Audacity using default values (Signed 8 bit PCM, no endianness, 1 channel Mono). The result is a choppy waveform with static. You can make out some audio, though.
I remember trying to import the file into a raw video player to no avail.
Opening the file in VLC player, then checking its Information ---> Codec, it shows the aOpenStream has 54 streams, mostly "mpga" and "mpgv" files. -Ghostbunny
- That's because the 3DO used MPEG Video and Audio... I think. It had a decoder add-on attachment, but I wouldn't be surprised if the games themselves used MPEG audio and video files since it did have some really impressive video quality for the time. // Foxhack 09:31, 6 July 2013 (EDT)
- I'm assuming it's possible to decode the files if someone writes a player then? --Ghostbunny 10:23, 6 July 2013 (EDT)
Some more notes concerning reading the disc's files and etc: Using 3DOResExplorer007.exe, aLeaderStream doesn't seem to be anything, aOpeningStream is the opening Electronic Arts logo followed by the game's introduction by the host and announcer, and BigStream would seem to be everything else but when BigStream is loaded via the above mentioned program, it plays the movie clips for the mini-games like Departure Lounge.
ZStream Chunks Reader (CHUNK080.exe being the latest I think) can be used to "cut up" the files into their proper individual files. For Twisted, there are 488 of them. The program doesn't seem to be able to do much for video but you can use it to convert the chunks into wavs. These alone don't seem to play in any normal media player (I use VLC) but you can play them in Audacity after a bit of fiddling around. To do so, open Audacity, click File, then Import, then Raw. Choose a file like BigStream0.sound.wav. Accept any defaults it shows (should be Signed 16-bit PCM encoding, little-endian byte order, 2 channel stereo). Now you'll need to to slow it down by half. You can do this by clicking Effect, then Change Speed. Set the percent change to -50 and click OK.
