REQ: Emu coding

[Agozer]

yeah and usually the gui's are made in C++ or C, everything else is assembly

Hardly, but a few years ago that would have been quite accurate.

Providing you're not hand-coding every opcode

<{POST_SNAPBACK}>

What would be the alternative?

[Madman]

opcodes are not regular codes. i.e. they are undocumented and unsupported, noone should use them, yet they exist.

They can, for example, do 2 things at the same time.

so you could have a decent working emu, that doesnt support opcodes. All games that dont contain opcodes will run, any game calling an opcode will crash then.

So the alternative would be to leave opcodes out (first)

[Agozer]

Which reminded me of the heavy opcode use in Nintendo64 games...

taratata, the alternative would be to use one of the many canned premade CPU core emulators found on the internet. Just search. Z80 has a ton of them. Mame is a gold mine for CPU emulators.

Yeah, that's true. Zophar's Domain (albeit the site blows chunks and they won't admit that the site is dead), that's one place to look for those CPU core emulators.
