I do computer things, mostly retro or retro-adjacent.
This thing is ridiculous. No, i can't put the controllers back on the sides.

Got a Souseiki Fammy in the mail yesterday. Gonna be figuring out FDS dumping in the coming weeks to get these disks backed up. I also plan on getting the rest of this device reverse engineered and documented.

Milestone reached: #Homebrew on the StudyBox! Getting this working was a bunch of really hacky code, so I've got a lot of cleanup ahead of me.

I've started to extract some screens from side B of that Darwin tape. It's a music program of some sort. And there's a horse race thing too? Idk.
Anyway, I'm doing more reverse engineering of this stuff tonight if you want to stop by: www.twitch.tv/zorchenhimer

I was able to extract some screens from that Darwin tape over the weekend. I've also confirmed that i need the Model 1000 firmware to play the tape. It will not run with the SBX-01 firmware.

I got my hands on a rare tape for the StudyBox Model 1000! This tape will not work in the newer model SBX-01 for a few reasons. If I can get a dump of the firmware for the Model 1000, we'll be able to play these tapes.

Well, the jump doesn't work perfectly, but you can't infinite jump anymore, also made movement smoother.

These are some of the reference pages I used for hand-assembling 6502 machine code programs. I learnt 6502 machine code on the CBM PET in 1979 and needed these sheets to look-up the opcodes for the instructions. I can still remember a lot of them today! Here's a test for you...A9, 4C, 20, EA, 85.

I finally finished all 5 shots of this little animation practice sequence. Had so much fun to combine Procreate, Clip Studio, Blender and After Effects to explore this style.

When I worked at Software Creations we used an in-house Editor/Assembler to create our NES games ( PC-ED ). This video shows NES Wolverine ( 1991 ) being assembled. The NES development system was attached to the PC via a parallel link and the object code was deployed to the NES for testing.

Real programmers use simple text editors. And no, that's not what defines them. Quite the opposite. If you start using simple text editor you won't become one. You become one when you realize that generating MBs of text per second is not real programming. It's just API plumbing.
