Would it be possible for programmers
to combine the usage of the 16 bit
and the 8 bit proccessors to create
an actual 24 bit game? Seems to me
it should be possible. <img src="graemlins/multi.gif" border="0" alt="[Multi Color Bouncey]" />

Please excuse my ignorance, only know real old shit like Commadore and Sinclair and jamma arcade stuff including Neo Geo MVS.

What console platforms were 24 bit ?

To be honest I get a lot of fun playing mame, love the old classics like Galaga.

Dont mind admitting that Ive never played a PS2 or XBox, there you go :) Call me an old fashioned bastard if you like.

Where did I leave the walking stick ?

Huh? The NeoGeo already uses both, the 16Bit-68K and the 8Bit-Z80 processors. <img src="graemlins/multi.gif" border="0" alt="[Multi Color Bouncey]" />

And again...the NeoGeo is a 16Bit machine, because the CPU only has 16Bit.

So are you telling me that the games are
24 bit? Because they seem to be 16 bit.
I just would like a more thorough
explanation of how this works. <img src="graemlins/spock.gif" border="0" alt="[Spock]" />

Oh no, not again!

We have three threads running now where ppl retardedly keep phantasizing about this topic over and over again.

Once and for all: The Neo is a damn 16Bit system with two processors/CPUs, one Motorola 68000 and one Zilog 80A, which, among other things, is responsible for some sounds, various x-tra stuff, etc.

Now, the Z80A is an 8Bit IC (read: has an address space with a width of 8Bit), while the M68k has a 16Bit wide bus, but the CPU (central processing unit) is the 16Bit M68k, the Z80A is just a co-proc.

The 24Bit shit stems from the early 90s and the efforts of some overenthusiastic marketing dudes at SNK. To successfully compete against companies like Sega (Master System, Genesis/Mega Drive), Nintendo (NES, SNES) or NEC (TurboGrafx/PC Engine), they simply added 16Bit to 8Bit and used this as their "weapon" against "pure" 16Bit systems.

So lemme' repeat that, there's no such thing as a 24Bit game console, never was, never will. It was just a made-up story to boost sales, that's all there is.
