Katherine the Sixth

of course I had to add Amiga ILBM support to the Irix image format tools

Something is wrong with my DECpc that I wasn’t able to figure out and made me frustrated with crashing and memory errors so I switched back to the big boi

I finally got my hands on a working P90 CPU card and we’re PS/2ing it SO HARD

yay. i can now type `make assets` and it automatically runs any conversions i need it to, going from .IFF graphics file to Atari bitplanes which can then be combined into a graphics ROM

Writing a ResEdit equivalent for my Atari 68K arcade assets here

Problem: Tyrian background tiles are 24x28px and Atari tilemaps are 8x8px. I can’t display .5 of a tile.

Solution: Treat two 24x28 tiles as one 24x56 tile. Now I can use a tool to turn each unique 24x56 combo in use into 3x7=24 8x8px tiles and build a graphics bank for my tilemap hardware.

this is ARM64. keep up the good work

While writing this ResEdit clone, I came up with the namespaces ASI (Atari System I) and ARK (Atari Resource Kit) so I could make bad puns with the binary export system.

@wohali@timeloop.cafe if it’s good enough for Elvis it’s good enough for me

I added an IFF -> tilemapped playfield conversion to my Atari graphics tools. Now I have scrolling backgrounds and I am liberated from manually punching in tile indexes!

today’s adventure is “how to allocate motion objects to actors out of an object pool while being able to sort them by Z ordering as a background task”

64 actors, 64 sprites, one actor can be made up of multiple sprites, at least I have a lot of RAM to keep track of it all on my cartridge
