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'm not convinced the colors are correct, but they're probably close.

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.

I think my license expires soon. Just a hunch.

I've been making a lot of progress on my NES Tetris project.

This is versus mode. I'll be implementing sending garbage rows soon(tm).

After having one of these for a while, I finally got around to taking decent pictures of the boards last month. I've been told this is a revision 1 boardset.

The screen shake makes the hard drops feel so much more aggressive.

I got ghost pieces working last night! There's still a long way to go, but it's mostly playable. This works on real NES hardware, btw (colors and all).

Scores, hard drops, & the ghost piece on the agenda today. Let's see how much I get done.

It feels weird making real progress on a project.

(yes, this runs on real #NES hardware. Don't let the colors fool you)

Would you believe I actually got data off this?
