Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Alternative designs for a keyboard interface?
I use a PIC16F microcontroller. Schematics and PIC code in my HBC-56 repo. https://github.com/visrealm/hbc-56

After Wozmon I want to create a game - 6502
If you're keen to add a VDP as u/production-dave suggested, I have schematics and a bunch of code in my HBC-56 GitHub repo

using an atmega micro-controller for managing multiple interrupts?
Schematics are here https://github.com/visrealm/hbc-56/tree/master/schematics/6502

TSM9918A | Questions asked by a friend without Reddit
The schematics for my TMS9918A display card are in my github repo. It uses a single SRAM instead of the original DRAMs. The circuitry between the TMS9918A and the TV is just a simple transistor follower circuit (shown in the schematic): https://github.com/visrealm/hbc-56/tree/master/schematics/tms9918

Small PS2 adapter
So this is really just cobbled together from this project by u/visrealm https://github.com/visrealm/hbc-56

Is my new second hand ps/2 keyboard broken?
I've actually just ordered the perix perrino 409 that sends the AA after self test. The HP keyboard definitely doesn't seem to be working. My plan is to interface it with a PIC microcontroller by copying the setup here: https://github.com/visrealm/hbc-56. from u/visrealm

6522 Shift register?
It looks like a shift register can be used in connecting a NES controller but likely isn't the full story. Check out u/visrealm's HBC build. He uses separate shift register chip to connect to a NES but maybe the 6522 can be used in a similar way.

After watching Matt Heffernan's Mandelbrot Battle Royale, I thought I'd give it a go on my HBC-56 (65C02 @ 3.6864MHz + TMS9918A). Four modes: 32x24, 64x48, 64x192 and 256x192 (sort of). . I still need to work on improving color bleeding in the final Graphics II mode. A bit of fun.
It's Assembly. https://github.com/visrealm/hbc-56/tree/master/code/6502/mandlebrot

4 cards down, 1 to go. No real issues since the R/W switch on the CPU card.
I have most schematics, software, emulator, etc on github. https://github.com/visrealm/hbc-56
-
Five new cards arrived today. Hopefully I didn't make too many mistakes...
These are for a 6502 build. https://github.com/visrealm/hbc-56

Immediate Mode GUI Programming

Black Triangles
It's fun to see the evolution in e.g. these examples of image loading for Dear Imgui:
https://github.com/ocornut/imgui/wiki/Image-Loading-and-Disp...
DirectX9 will even load the image for you, DirectX11 okay we get a few more structures to fill out, DirectX12 is where it goes off the rails and we are filling out a bunch of UNKNOWN DONT_CARE JUST_DO_IT. Then of course Vulkan is the one that gets the big fat "this probably won't actually work for you" warning.
I understand whats happening, but you know sometimes I just want to display a fucking image.

Dear ImGui: Bloat-free Graphical User interface with minimal dependencies
ImGui is engine/GPU agnostic
Themeing isn't a just a retained mode thing, you can do wonders with immediate UIs, even thought (dear)ImGui doesn't provide much, you can still do wonders: https://github.com/ocornut/imgui/issues/707#issuecomment-362...

Where do I start to learn C++ for a game development
Bonus: If you want to make desktop app with UI, then this is another great C++ library and it's also simple to learn as well. https://github.com/ocornut/imgui.

GUI library for fast prototyping
AFAIK the Rust equivalent to C++'s Dear ImGui is egui.

Stretching myself thin with Dear ImGui projects
They use a Dear ImGui, a C++ GUI library.

PCSX2 Disables Wayland Support
Aside from bugs and driver issues, Wayland has some unfortunate design limitations. For example, Dear ImGui multi-viewports don't work because "Wayland doesn't let application read or write windows positions."
https://github.com/ocornut/imgui/wiki/Multi-Viewports
This is a feature available on Windows, macOS, and of course X11. Making choices like this means desktop Linux becomes even more of a weird island that nobody wants to support.
