Maze generation in gigatron assembly
Hi gigatron community, in the last weeks, I've managed to implement an iterative maze generator in gigatron assembly that I'd like to share with you: https://github.com/kervinck/gigatron-rom/tree/master/Contrib/tbraun-de/gasm I think it's kinda mesmerizing watching the maze grow again and again, esp...

Gigatron Emulator for Mac OS X (first test version)
Hi Gigatron Community, in order to get to know Gigatron better, I decided to try writing my own emulator for Mac OS X in Objective C using Apple's Cocoa Framework.

Try to subtract 2 from the low byte you put in [$16] and [$1a]. That was it, hooray! The emulator is now working rather well. Thanks a lot for your help! I'll add the emulator to the Contrib section once I'm happy with the codebase and the featureset. Best regards and thank you again for your great...

Re: How does Loader expect GT1 data to be presented?
Thank you very much for your answers, at67 and marcelk! I'm certain they will help a lot! For a start, I'll try putting the bytes directly in my emulator's RAM to find out if things work as expected.

Hi Gigatron community, I'm looking forward to building my own Gigatron during the christmas holidays. Until then, I've started writing my own simulator/emulator. I do know that there's already a fully working javascript emulator by PhilThomas and another really complete one written in C++ using SDL ...
