How to open .GDI file (beginner)

Post by Mervin »

Hi, im new to all of this, so bear with me

Basically i downloaded an nzb of a dreamcast game - redline racer,

Extracted the .rar that i got, and now i have 12 bin files and a .gdi file...

How do i sort this out? How do i apply this to an emulator etc..

What do you guys reccommend?

Thanks

nullDC is a new Dreamcast emulator that can use gdi files with a special plugin that is included with it so you can play the game in it's original GD-ROM format.

Well to be honest I haven't used nullDC since the first public beta so I'm not sure what the problem is. Hopefully someone here that has had experience will reply.
