September 05, 2021 — G1n

This week I have published gxt, but it currently works as more (only down scrolling). Also it has a lot of of runtime error (Segmentation fault and others).

I have started working on yemu - Yet another EMUlator. It currently supports only 6502 proccessor with tiny number of instructions (LDA, LDX and LDY)

Today we have fixed interrupts in Orion and now I can implement timer, paging, keyboard and a lot of other things (thanks to quinn and smlckz from

GRU Devlog 5 - First contribution from other person, coreutils and gxt (tui text editor)

August 29, 2021 — G1n

This week I had a lot of new ideas. But I think we have to work on something that have already been started. Also we now have one more coreutils rewrite (now on C to more easily port it to Orion in future).

Also i have started working on some projects that is not ready to be published yet. One of them is gxt - tui text editor.

Currently it can only move cursor and display files. But I think I’ll publish it next week when editing will be working.

Bad news is that my school lessons will start next week so maybe this devlogs won’t be published every week, because of not enough work done. But I don’t know, maybe I’ll have enough time.

Also good news - we have first contribution on codeberg to grsh. I didn’t know this person (because he is not from tildeverse :) ), so it is cool!

Hope you liked this devlog! If you can somehow help us, please contribute to our projects on tildegit/codeberg and/or message me in someway :)
