I like how the Z80 was used as an audio chip when it got too outdated to be the main processor.

This kinda happened to the 6502 as well, but only on the snes.
the SPC700 sound computer actually used a souped up version to control the sampler thing, and could actually do some things the main CPU could not.

Such as?

>>337544635
Z80 was also a processor for backgrounds and other shit in the Genesis, but also key to master system backwards compatibility. Too bad you just don't see that kind of shit anymore, and Wii U will probably be last console to ever have true BC

>truxton is not an argument

Fuck off, Derek.

The NX still has a chance to have backwards compatibility. Provided we know what the hell it actually is. And going forward, all current gen games are going to work with their successor consoles thanks to UWP and etc.

Still there won't be any additional processors or other misc. chips in future hardware. For the best, really.

Multiplication and division.
The main snes cpu "can" do that by using the PPU multiply register things, but it don't have a mul or div instructions.

Huh I never heard that one before, thanks for that.

It's not exactly common knowledge, so i got quite surprised to find out about that as well.

Here's sauce, that shows it can into modulo as well:

>8-bit SPC700, runs at ~1Mhz …with the effective speed being half (each instruction takes a minimum of 2 cycles)
>Main/Echo volume! 8-bit signed values. Regular sound is scaled by the main volume. Echoed sound is scaled by the echo volume.

This is an excellent source of information, thank you! Fraid I don't have much to give in return, sorry.

Just have fun.

Thanks, mate.
