Hello, my name is Brian. I make neat things with computers. I also drink a lot of iced coffee.

I'm still mucking about with Sega Master System Z80 assembly. Got my old man moving around the screen with dpad input, animation, and basic collision detection with a lovely cup of coffee.

Spent so much time chasing non-issues as a z80 assembly noob, but I finally got my little old man animating (as a group of sprites) front and center. Baby steps ...

I went further down the rabbit hole and assembled my first Sega Master System ROM. Here it is running through an SMS FPGA core on my Analogue Pocket.

Ran the image through png2tile (github.com/yuv422/png2t...) and it looks like it would fit into 185 tiles.

I read somewhere that Alex Kidd was originally going to be a Dragon Ball game before Sega lost the license. I made this Son Goku splash screen using only 14 colors of the Mark III/SMS palette. I haven't done a tile count yet but I think this would have been doable on real hardware. #sega #dragonball

I picked up Elevator Action Returns S-Tribute (on the Xbox). It is a nicely executed game with engaging game mechanics. It is incredibly fun to play. I would have loved to have played this arcade port on original Sega Saturn hardware back in the day. I might double dip and buy it for Steam as well.

Spent the last three plus hours getting acquainted with Visions of Mana. Such a wonderful way to spend a Sunday afternoon.

Finished South of Midnight. It was a delight to journey through this haunting adventure as Hazel Flood. She is an amazing character. And those environments... absolutely stunning. Thank you @compulsiongames.bsky.social for creating this wonderful experience. #southofmidnight #xboxseriesx

Finally completed It Takes Two yesterday with my youngest as my copilot. What an absolutely wild experience. There are so many interesting gameplay mechanics that are enhanced by the brilliant two player cooperative design. Much love to the development team that built this crazy wonderful game.
