CHIP-8 Emulator for PCE

OldRover · 12/09/2009, 03:17 PM

For some reason, Neko talked me into doing this, hehe.

It's the start of a CHIP-8 emulator for the PCE, as the title suggests.

Here's an early shot of the emulator with about 75% of its instructions coded. Graphics don't quite work properly yet.

Also, there's no controls or sound just yet. I started with an easy program: MAZE. Just 38 bytes. Once it's completely working, I can attempt to emulate the more complex programs.

This is only intended to emulate the original CHIP-8. For now, I don't intend to support SCHIP or any of the other extension versions. This is just for fun after all.

All of the code is 100% original; not lifted from any other source. I'm going solely on the meager documentation of the system and looking at CHIP-8 program code in a hex editor to make sure everything checks out ok.

You can see it here:

CHIP-8 is a language that was designed to program games like Pong in the past. When you develop a program in this language, you need a "CHIP-8 virtual machine" to run it.

Well, I think that The Old Rover is programming a "CHIP-8 virtual machine" to be executed in the PC Engine, so that you will be able to run "CHIP-8" games in a PC Engine. And it is impressive, because... well, we know that there are consoles with a large scene of emulators (you can run emulators of other systems in a Dreamcast, a Xbox, a PSP... but I don't know if anyone has made previously anything similar in the PC Engine

Keranu already did this (or someone else)...but he had it running at MGC a couple years ago.

No he didn't. I said original Pong, not a port with a bouncing bonk smiley and TurboPad paddles.
