Dreamcast File Format Help

[jch02140]

 
Hi,

I have been searching around trying to find someway to convert the dreamcast *BGM files to music files that can be played in windows.
I read in some placed that many DC games uses MIDI format with Yamaha based sound system to render the music...

Also, I am wondering what are the regular models and textures files format stored in dreamcast games?

I have a DC CDI file, extracted the content using CDMage and found the following file formats:

• ADX
• BGM
• CGM
• NJ
• NT
• OSB
• PVR

Any help would be greatly appreciated...
