I know there is a benchmark program available but not to what your looking for. The one i'm talking about was for use to pop right into the system and see what its running at. Was mostly used for people who wanted to over clock there Dreamcast. Overclocking the Dreamcast is not the best way to run games either as most games wont run and some will so you pretty much got a Dreamcast that has been poorly updated. A wicked idea for that was if the system could have been fully updated with a new video card and such but thats pretty much impossible. Even doing that would make no sense who is going to make games to look that amazing on the Dreamcast compared to whats available today.
