the 68000 is a 16bit cpu
the z80 is an 8bit cpu

There actually was a home version of it too but I dont think it caught on at all. I think its called CPS changer too or something.

>>1006269

That was based on the CPS1.

But there are fan made console CPS2 systems.

>Main CPU : 68000 @ 16 MHz
>Sound CPU : Z80 @ 8 MHz

so it's pretty much an overclocked genesis/MD, that's neat

CPS2 is a sweet system and I've been thinking of building a harness for my World Warrior cabinet to put a CPS2 in it. The suicide batteries just suck though. Now's the time to get them and save their lives although I guess now that the roms have been decrypted you can put the unencrypted rom onto a suicided pcb and have a cps2 cartridge that doesn't need the battery.

saying something is X bits doesn't mean anything

The Sharp X68000 was very similar to the CPS series. It was even used in the development of CPS2 games. Playing some of its games would give you the best idea of what a home CPS2 would be like.

The battery is not much of a hassle to change, also dead games can be revived burning the program eproms with decrypted data.

If you already have a jamma compatible cabinet(I assume your world warrior is one) you only need a cps2 kick harness in order to play fighters.

The 68k and Z80 were some of the most common processors in the 70's and 80's for computers, and there were a lot of arcade machines that used them in combo throughout the 80's and 90's.

>>1006315
Yes and no. If you're talking about the "adding processor bits together" like the Atari Jaguar and N64 did to come up with their bit rankings, then yeah that was them not even following what makes a console a certain bit rating to begin with, the bit rating of either it's CPU or most powerful processor. Jaguar and N64 are both 32-bit consoles, just like every other 5th Generation console was.

The bit designation of a processor isn't very useful by itself without context provided by the other statistics, but generally a higher bit processor is better than a lower bit one. You'd have to be an idiot to think that 16-bit processors like the 68k and i386 aren't better than 8-bit Z80, Motorola 6800, Intel 8080, or MOS Technology 6510.

calling a console X bits makes no sense, calling a CPU X bits either

the Z80 for example has 8 bit registers and data bus but a 16 bits address bus. It also has some instructions to work directly with 16 bit numbers

it doesn't mean shit, X bits is just the size of some component of the CPU, it can have components of different sizes and the size doesn't have such a relation with power

the fact that CPUs with higher size components are better is just because it would be unconvenient and stupid to make them have smaller buses and registers, but you can do a modern CPU with 8 bit registers that is as fast as current CPUs, it's just retarded to do it

Like I said

>The bit designation of a processor isn't very useful by itself without context provided by the other statistics

Any individual statistic of a processor isn't enough to make a full judgement of it. Clockspeed is useless without knowing how many and what kind of instructions a processor can do in a single cycle, and comparing two dissimilar processors on their clockrate alone is retarded, like MegaDrive/Genesis fans like to do with the Motorola 68k and Ricoh 5A22. But, in and of itself, having a higher clockspeed or bit rating is an advantage, plain and simple.

fair enough, just thought it was interesting that both processors are used for the same purpose in both platforms (68k for main logic, Z80 as a sound co-processor)

>>1006438
Don't get me wrong, the 68k/Z80 combo was really good combo. The Neo-Geo uses the same set up and look what it can do. It's the reason why the Genesis had so many good arcade ports compared to other consoles because of the similar hardware.

>>1006381
Incorrect, N64 actually did have a 64-bit CPU.

>>1006492
The VR4300 had a 32-bit bus. Calling the Nintendo 64 64-bit is as retarded as calling early Amigas or Atari ST's 32-bit when their main processor has a 16-bit bus.

>>1006259
It's a 16-bit system. The main CPU has a 16-bit external bus, and a 16-bit word size (32-bit ALU, though).

>>1006293
The sprite engine was LOADS better, though. Old consoles' capabilities were defined by their video hardware, not their processor. The Genesis, System 16, CPS2, Neo-Geo, and a bunch of dedicated boards all used a 68000 and a Z80, but had totally different video hardware.

>doesn't believe me when I tell him that x86 is a monstrous pile of shit with 16-, 32-, 48-, 64-, and 80-bit-wide parts

>>1006349
Yeah, that's what I said... Also The World Warrior is CPS1, obviously.

>>1006543
Aren't there 8 bit parts to keep compatibility to the 8088?

An hardware similiar to Genesis.

>>1006543

Your dad must be pissed. He saw the birth of the industry but has to suffer through our current 20+ year run of still being hamstrung by some of the same limitations he was.

By today's standards, it's 16bit because of the main cpu, the 68000.
In the past some people (Atari) called the 68000 a 32 bit cpu because of the register size. But by that logic, the Z80 would be 16 bit which is utter nonsense.
Some console producers also tended to accumulate the bits of all CPUs,
so 68000+Z80=24bit or, if you see the 68000 as 32bit and the Z18 as 16bit,
it would be 48bit. Utter nonsense again.

>>1006313
Just did exactly that today. Upgraded from World Warrior to Super Street Fighter II. It's totally worth it man! I'll upgrade to Super Turbo when I get some more money but for now I'm just happy to have all the characters.

>>1008643
See this guy knows what I'm talking about lol.

Did you rewire or just build an adapter? I have an aversion to knocking out compatibility. I'd probably even leave my World Warrior board in there. It's got a fun message that says it's illegal to play it in the US, Japan or Canada.
