Happy 2024!. The 486 DX4 turns 30 years old in March. It's the CPU that got me into real-time graphics and the #demoscene. That’s why I target it in almost all my #retroprogramming projects. To celebrate, I've coded a blur effect in true color optimized for the DX4!. Code in 🧵

I've managed to implement NMI Interrupts in C with cc65 ⌨️😃. 1/2. #c64 #C64Retweets #cc65 #8bit #VSCode #retroprogramming

Trying to implement load/save functionality into my engine and I accidentally read the tileset as the tilemap with some amusing results:. #gamedev #msdos #retro #retroprogramming

Didn't have any of my own sprites on hand so I figured I'd use a sprite that @ketirz made of her OC Kit O'Byte, which fits with the whole cyber theme my test program's got going on. Running super smooth on the 5x86 133mhz!. #gamedev #retro #retroprogramming #msdos

I've finally find some time and figured out how to do raster interrupts in C with cc65 ⌨️😃. Every day things seems a bit easier😎. #c64 #C64Retweets #cc65 #8bit #retroprogramming

Here is my DOS game engine running with the (super basic) entity component system I've been working on for the last week or so, which I'm stuck testing on the Hand386 until I can get my hands on another monitor. #gamedev #indiedev #msdos #retro #retroprogramming

Finally implemented a custom keyboard interrupt into my MS-DOS Mode X game engine. WASD movement in 8 directions is so smooth on the mini-386!. Perhaps sometime down the line I can also add Gravis Gamepad support. #gamedev #indiedev #msdos #retro #retroprogramming

I've set up the groundwork for future projects using Forth on my trusty Commodore 64. 💾🚀 #retrocomputing #forthprogramming #commodore64 #c64 #retroprogramming #retrocomputer.#Forth

Just spent the last few days diving into Osca64, and the result? A simple Snake game using double buffering—no raster interrupts needed! Coding was an absolute joy. It's amazing what you can achieve with the right tools! 😎#Osca64 #retroprogramming #C64Reposts #8bit #C64

Just got '20 Goto 10: 10101001 Facts About Retro Computers'. It brilliantly explains binary 2's complement for negative numbers. A must-read for retro computing fans! 📚🖥️ #RetroComputing.#retrocomputer.#commodore64 .#c64.#retroprogramming

Still same frame rate. The new blit with saturated addition takes 43 cycles per pixel in a 486. I think not bad given that there is no saturated add instruction; that was first seen in Pentium's MMX. #RetroProgramming

I'm inexplicably getting a lot of joy out of the most irrelevant programming tasks, like finding the optimal code for this bit-fiddling job. This is the best I came up with so far. Any tricks up your sleeves, #m68k assembly pros? #retroprogramming

Experimenting with KickAssembler features! Macros enhance code readability and structure. At first glance, it might not be obvious that this is MOS 6502 Assembly. 💡 \.#Coding #KickAssembler #MOS6502 #100DaysOfCode #Retrocomputing #Retroprogramming #Commodore64 #c64
