Since both the Gamecube and Dreamcast versions of Sonic Adventure 2 Battle i would like to see if i can put some of the dreamcast dlc back into it and maybe try to do some custom things but i don't know how to get into the VMI and VMS files. Is this possible?

As far as I'm aware, the VMI file is irrelevant, containing only metadata. The VMS contains all the data read by the game, and a header formatted like this.
As for the format of the data itself, well that depends on the game, what it's used for, etc. Quoting sonicblur on Sonic Retro's SA2 hacking thread:
Originally posted by sonicblur The XMAS and Halloween downloads for DC SA2 just unlocked textures already on the disc. The only SA2 VMU downloads that actually had new data inside the VMU download file were the Kart Race downloads. You can unpack them with a normal PRS decompressor after removing the VMU file header, and the models and textures for those are easy to find. You can't do this with SA1 downloads unfortunately, because they encrypted them.

Thats interesting, so in other words if i grab a Dreamcast ROM of Sonic adventure 2 i can get my hands on the files. I'll do that right away, I don't really need the karts anyway.
