Lol, Dreamcast is a 128bit system, so I'll bet that is what confused him.
Ram wise it only has 16mb. Video ram its got 8. total that's 24mb's. The Dreamcast actually has double the video ram of the PS2's 4mb.
Anyway, not sure how to explain the 128bit part, but I will let somebody else smarter take a shot at it for you.
The funny thing about the Dreamcast is that its a mixed bag of chips, Its not a true 128bit system, The CPU is a 32bit with an on-die 128-bit vector graphics engine. the arm7 CPU is a 32/64bit hybrid chip which is a audio controller.
The definition of a “Bit” is that it is a unit of measurement of information.
I never realised the DC had an arm7 cpu. I always thought it was a Hitachi risc CPU with a Videologic Power graphics chip and a Yamaha audio chip. I was also led to believe it had 26 mb RAM. I'm not that knowledgeable about these thing though, that's what I was told years ago and it's stuck in my mind ! lol

It does have a hitachi cpu.The sh4 cpu takes care of t&l on the dreamcast,which I guess means the gpu doesnt generate the polygons but the cpu does while doing transfromations and lighting?.also it does have 26 mb of ram, its something like : 16 mb main ram,8 mb video ram and 2 mb for the sound chip.It does have a arm cpu in running to work with the yamaha sound set up.On dcemulation.org they are discussing the arm cpu and how badly it was implemented and how very useless it is in the grand scheme of the machine.
Wow this is awesome! I really cant wait to see some results . I hope this gets a disc release as im sure it will get very good support from the community.

Back on topic!! No further news on this one lately then? I can't wait for Tahi but something tells me it will be another 5 years plus before we see the results lol
