TI-99/4A dev update #1:
Got smooth sprite movement working by polling the VDP status byte (>837B) to sync with vertical blanking. This is all still GPL for now, but Iโll probably move the heavy lifting to assembly later for more performance headroom.

Dusted off a small tool I wrote a while back for dealing with TI-99 graphics. I create tiles/sprites in mtPaint and save them in PPM format (cause it's really easy to parse). Then I feed the PPM to my tool and it will spit out the proper bytes for use in the assembler.
TI-99/4A dev update #2:
Made a simple demo of keyboard movement with a sprite. Starting to switch from GPL to assembly.
Ultimately I want to make a physical cartridge. Assembly only requires ROM. GPL requires GROM, which has to be emulated and costs more.

I'm not really a golf guy but I still have the weird affinity for golf games.
Recently found out there was a Golden Tee collection so I picked it up for Switch. I played the heck out of the Golden Tee (1998) PC demo back in the day.
Any golf favorites?

Anyone else a Game Center CX fan?
That show was my gateway to so many hidden Japan-only Famicom gems Iโd never have discovered otherwise. Arinoโs suffering is legendary.
Two favorites in my collection:
- Astro Robo Sasa
- Challenger
