CHIP-8

Edit: and from where can I download them

Version 4.2 adds a couple of new tests to the Corax+ and Quirks ROMs.

The CHIP-8 test suite is a collection of ROM images with tests for CHIP-8, SUPERCHIP and XO-CHIP interpreters (or "emulators"). The main goal of the suite is to provide reliable tests that find edge cases for those opcodes, so implementing CHIP-8 is more fun and the resulting interpreters more compatible and historically accurate.

After reading and completing the exercises and projects from K&R 2nd edition and C Programming a Modern Approach 2nd edition, I wanted to continue my C journey (love the language). I wanted to work on a game, but do it all from scratch where possible, so no graphic libraries etc. However, I thought I best start smaller, a lot smaller! I've set my sights on writing a Chip-8 emulator, and so far it has been a lot of fun. I've only got enough instructions written to run IBM Logo.ch8, but getting the drawing routine working was a right pain in the arse!

I actually did a few fist pumps when I got the IBM logo to display. :D

I also want the option of getting it to work on other platforms relatively easily, so I've separated (as best as possible) the emulator and platform specific code into their own layers.

Once finished I'll get it on GitHub for anyone interested. I was just so happy to get the drawing working I wanted to share that joy. :D

Not sure how to add a picture, but here's a screenshot of what caused the fist pump.

Hello everyone, I wrote a chip-8 emulator and I'm just looking for someone to critique my code. I'm not happy with the code structure and how I'm handling stuff with SDL but I don't really know how to fix it. Could anyone tell me any pointers on what I can fix/improve. Here's the Github link:

Thanks for the support, It means a lot

Hi,

About a year and a half ago I got into writing Rust by writing a CHIP-8 emulator. It was much more fun than I thought it would be so I extended it into a toolkit and wrote a disassembler and then a debugger for it. I figured it might be nice to include support for popular variants so I added S-CHIP and XO-CHIP support. At the time I was kinda obsessed with TUIs (terminal user interfaces) so the whole thing runs from the terminal. At some point, I got quite busy and just didn't have much time to continue working on it.

A couple of days ago I thought it's been a while and the project is just sitting there. I figured I should share the project with others if it has any value so I cleaned up the readme.

I would greatly appreciate any feedback. Give it a shot and let me know what you think. I'm not actively working on the project for now but I am open to PRs and the sort.

Hey! Hope you all are doing well! I wanted to share with you the results of my third attempt at writing a CHIP-8 emulator.

When I wrote my first CHIP-8 emulator I used .Net and C#, but I was just starting out with programming overall and the result was functional, yet quite messy (the link to this particular implementation is part of the .README of the project).

I tried to use C++ for my second implementation, but C++ is not one of my strongest areas of knowledge, so was I was mostly fighting the compiler for the entirety of the development process (this project is not open source).

Now I was finally able to achieve a result that I happen to like and despite the fact that I haven't touched it in a while, I'm pretty satisfied with the overall implementation. I wanted to thank everyone on this sub, because some posts and even some comments were pure gold for me while I was working on the project (in fact I was able to get the CPU ticks right, because of one of those comments).

If any of you happen to be interested in taking a look at the result, feel free to check the repo c:

PD: Implemented using Rust and SDL2. I was able to get sound, graphics, controls, and even save states right in this iteration. Thanks to all of you, now I even have a clear idea of what is required to implement rewind c: (I'm planning to work on this in a non-so distant future).
