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).

Okay, rasterizer didn't work (no surprises), but blitting and screen clearing rates are way faster than before. Now I'm convinced this setup and my blit/clear assembler algorithm are viable for the engine. Woohoo! 🙌
Time to re-design the rasterizer...⌚

More performance testing, I've switched to [ISA] Tseng Labs ET4000AX from IBM VGA, seems like a huge win in terms of VGA write speed! Also I've written Abrash-style triangle filler. I'll have results soon...

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!

YES! I've finally been able to create my MAKEFILE building system that unifies DJGPP with NASM. What a relief for today... 😮‍💨
