I'm Burak, a computer scientist, graphics programming enthusiast and a gamer. I love graphics engines, currently working on my own engine for the cyberpunk themed retro styled game.
Spent the night chasing down an instability in renderer's projection stage. Turned out my new saturating divider had a flawed overflow check. Every perspective divide was “overflowing,” so vertices were flying out! Details in devlog:

I'm still working on renderer, wrestling with correct vertex clipping for the latest Harmony Tree update.
The build we uploaded earlier as the #CyberVGA engine test for the #DOSember jam exposed several edge-case failures in the current wall/vertex pipeline.

Off-topic: Is a degree what makes a mind curious? Does walking away from school mean walking away from science? Or is it possible that some of us just learn better when we’re free to explore the unknown? I just wonder…

Been quiet for 2+ weeks—went deep into 32‑bit x86 ASM mines. Back with big wins: faster Mode X page flips, RAM→VRAM blits, sprite pipeline + 256‑color palette, a lean fixed‑point renderer and strong assembly knowledge. Old‑school DOS, new speed. Demos next.

So box made of raw pixels didn't filcker or misplaced and I've finally been able to blit raw pixels at desired page in ModeX. Old font renderer seems like need a bit more work regarding page selection though but at this point, that's ok. 😮💨

Struggling with ModeX... 😩
This is driving me crazy, beacuse it took more than a week to implement and I'm still having problems with v-retrace flickering and page offsets (I think).

A few days ago I was thinking that going full ModeX feels like cheating for performance. But now I stand corrected, ugh. In short, Abrash explained that it is a VGA pandemonium;

Here Tim Cain tells the story of not taking credit on a reissue of a CGA game on which he was tasked with adding VGA support by hex-editing the executable. No game or company was named. I saw only one good theory in the comments, but unfortunately it doesn't quite fit.

Font rendering (FPS + profiler) added. Switched from full-frame memcpy to a dirty-rect blitter (copy only changed rows). 600+ tri wireframe now ~30 FPS in VGA 13h. I'm using 86box with 486DX2 66mhz and 16mb of ram.

I've completed porting my earlier wireframe renderer, which uses fixed point maths & custom mesh format. Everything seems to be working fine. Comin’ up: performance testing and vertical span rasterizer!
