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.

There's really only two file formats

Working on my #NES #Tetris ROM on stream. Two player garbage attacks is today's focus, come take a look! www.twitch.tv/zorchenhimer youtube.com/live/2Xzk5KM...

Well, the jump doesn't work perfectly, but you can't infinite jump anymore, also made movement smoother. #gamedev #inidiegamedev #BRdev #BrazilianGameDev #homebrew #homebrewdevelopment #retro #retrogamedev #assembly #assemblylanguage #gameboy #Celeste #CelesteGame

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.

Tagging @ramiismail.com as he might get a chuckle out of this. But it's a great read for all programmers!

Finally back to making progress on my #NES version of #Tetris. I got T-Spins working! #nesdev

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.

Gunnerkrigg Court limited edition book came in the mail today. Wasn't expecting NUMBER TWO

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.

Back to some software dev today. Working on some retro dev tooling, focusing on graphics stuff. www.twitch.tv/zorchenhimer

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.

Playing some Momodora: Moonlit Farewell cuz I'm too burnt out from work to code. www.twitch.tv/zorchenhimer

the most important aspect of kernel development is to make sure your driver freaks the fuck out whenever the system resumes from sleep

I'm gonna try and get wall kicks working again today. Let's see how far I can get. www.twitch.tv/zorchenhimer

So I picked up some soju tonight... www.twitch.tv/zorchenhimer

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).

Tech is kindergarten. All devs are children. And we need adults in the room to clean up all their toys.

I need to post more. Anyway, I'm refactoring more 6502 assembly to be faster. Come hang out. www.twitch.tv/zorchenhimer

A little late today cuz work was a dumpster fire. www.twitch.tv/zorchenhimer

So i heard you like T blocks. Live in 10 minutes: www.twitch.tv/zorchenhimer

E3 2010 is in 1 hour at magfest. Panel room 6.

Sake and assembly. What could possibly go wrong? www.twitch.tv/zorchenhimer

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

I'm live. Come say hi. www.twitch.tv/zorchenhimer

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. www.twitch.tv/zorchenhimer

It feels weird making real progress on a project. (yes, this runs on real #NES hardware. Don't let the colors fool you)

get rotated, idiot www.twitch.tv/zorchenhimer

Would you believe I actually got data off this?

I've had an account here for a while, I should probably start using it. I'm making a Tetris clone in assembly on the NES, come hang out! www.twitch.tv/zorchenhimer
