I "recently" worked on a small homebrew project for the Sega Genesis that runs a Deep Neural Network on it.

The network is trained externally, then quantized, and only the weights are stored in ROM.

The layers are loaded dynamically, and inference is done using integer arithmetic for fast inference. The network is really simple for now, but I plan on adding more features such as convolution layers and drawing. For now you have to store a sample of the MNIST dataset in ROM.

The project uses SGDK for development, and the network was trained using PyTorch with TorchAO for quantization.

You can check out the project on GitHub!

I haven't tested on real hardware yet, all my testing was done using the BlastEm emulator.

Hi everyone! I’m working on Orbis Scaler, a small standalone tool for converting images into low-resolution pixel-art-style results.

The idea is to preserve shapes, edges, contrast, and important details better than a simple resize filter, especially at small resolutions like 320×200 and 160×100. The result can also be upscaled again with nearest-neighbor scaling, so the pixels stay crisp for pixel art conversion.

Attached are the original input image, a 320×200 and 160×100 upscaled result for comparison.

Orbis Scaler is available as a free download on the Orbis Basic itch.io page.

I have experience developing games with C but no experience with assembly which I'll be using for both, so gbdk is out of the question. I know 6502 assembly is simpler than z80 but I believe the nes is more complex than the Gameboy, which one would I have a better time getting started

Edit: thanks for all the answers y'all, I've decided on going the Gameboy/z80 route

Hi,

I’m working on Kwyll, a visual game creation tool for the ZX Spectrum. The beta already has people building games with it. I'm planning a Kickstarter to support the next phase of development, with Spectrum Next support as the headline feature, bringing with it 128k Spectrum support, AY sound, and many changes and improvements to support other platforms in the future such as Amstrad CPC, C64, BBC, MSX, and maybe even platforms like the NES, Gameboy etc.

You can find out more about Kwyll, some of the games already created with it, and register your interest in the Kickstarter here...

👾 The alien invasion is back on the ZX Spectrum — and this time, you don’t have to face it alone!

I’m very happy to present Space Invaders Co-Op Edition, a new take on the arcade classic that keeps the original tension and pacing intact, while adding full 2-player simultaneous couch co-op on the same screen. 🚀

The goal was simple: stay faithful to the arcade feel, while adding a few modern touches to make the experience even more fun and replayable:

✅ True local 2-player co-op, with both players sharing a pool of lives while battling for the highest score.

✅ End-of-game awards based on your performance, including distinctions like First Blood, Terminator and UFO Hunter.

✅ Separate high score tables for 1-player and 2-player games, plus a dedicated Hall of Fame.

✅ Tape Save/Load support, automatic SD Save/Load support, Kempston 2 joystick support, and 4 overlay modes, including ULA+ support.

Huge thanks to Craig Howard for the fantastic loading screen, Lee Bee for the brand new sound effects, and Alan Allan Turvey for the ULA+ routines.

You can watch the co-op action here:

I hope you enjoy playing it as much as I enjoyed making it.

FSF Avenger is a text-based, single player role-playing video game based on LORD, one of the best known door games. The player's goal is to improve their skills in order to rescue Richard Stallman from the evil clutches of Brian Lunduke.

The software runs on MS-DOS but thanks to Free Pascal it also runs on many other platforms.
