TurboGrafx-16 / PC-Engine

This is a Rust emulator for the TurboGrafx-16 / PC-Engine console. It is a hobby project to learn more about emulation and the inner workings of this console I wish I had as a kid. It is by no means feature-complete, but it does run games like Street Fighter II and Bomberman, so it's not entirely useless either.

Overview

The TurboGrafx-16 has a few main components that need to be emulated:

The HuC6280 CPU, which is a modified 65C02 processor. I use my own mos6502 for that.
The Video Display Controller (VDC), which handles graphics rendering.
The Video Color Encoder (VCE), which handles color output.
The Audio Processing Unit (APU), which handles sound generation. (Not implemented yet)
CD-ROM support (Not implemented yet)

There are still some glitches around grafic effects. Some games might not boot. Also, I don't ship the ROMs for copyright reasons, so you'll have to provide your own.

Screenshots

All of these were captured straight out of the emulator (see examples/dump_frame.rs):

Street Fighter II'	Bomberman	Splatterhouse

(Castlevania doesn't run yet, because I don't have support for CD-ROM games yet.)

But Why?

This started as a test-project for the mos6502 CPU crate, but it turned into a full emulator.

Besides, the TurboGrafx-16 is a great console! In comparison to other consoles of its time, it had a lot of advantages:

It did NOT have a 16-bit CPU, but rather a Modified 8-bit CPU.
It had a dual 16-bit graphics processor, which allowed for fancy graphics effects like parallax scrolling and sprite scaling.
Games were initially released on HuCard cartridges, but the platform later added CD-ROM support, which allowed for larger games and better audio quality.

Overall, a great console that was ahead of its time, but unfortunately it was not as popular as other consoles like the Sega Genesis or Super Nintendo Entertainment System (SNES); mostly because of marketing and distribution issues.

Hacking

I recommend spelunking around in the source code. It's not great right now and I need to do a makeover, specifically making it more Rustic and less imperative. If you'd like to help with that, feel free to submit a pull request.
