I ported @64abstract.bsky.social's Carve Your Own Path to MMC5, totally not going to use this to test something 😉 #nesdev

When you declared the type wrong so the last tick value keeps getting truncated within 8 bits 😵‍💫

Style test 🤔 (cover of MelonadeM's Perpetual Motion) #chiptune

That's right! I helped my friend Abyxus compiling his impressive 2xSID tune into a single .sid file, which is normally impossible due to music engine restrictions. Had to make some modifications to patch in the second half at runtime 😄 www.youtube.com/watch?v=6YHc...

Ominous

Have you ever spent almost a month of free time rewriting the hardest piece of cycle-counted code and having so many demotivations in-between, just to find out it doesn't work in the end? Yes, that just happened to me 😭

Man I like Motorola 68000

I finally went back to my usual place where I can upload to YouTube. The full video of the cover will go live tonight! youtu.be/9LkTz279sd4

"It's time to get rid of that complicated mess. Newly designed doesn't always mean it's good~"

That's right! The cover I've been wanting to test my sound design on is finally finished! Enjoy this single YM2151 cover of Zylenxx - Upgrade! Full YouTube link in comments once I go back to my place in Sunday Oh right, background pic unrelated, of course 😉

I regret to inform you guys that I'm currently locked out of YouTube uploads since I forgot my old phone which has an Authenticator registered at home 😭 However I'll instead post a 2-minute preview here. I'm very sorry for this unexpected scuff

Hi everyone! As my birthday is coming near, I'm glad to announce that I'll be premiering a new song cover! YouTube link will be up soon™️

So my main keyboard's 6 key has died. I finally got to troubleshoot it today and turned out the diode at DW12 is broken 😔 Which means I have no way to repair it properly without buying new parts

Announcement regarding Project Aiko Following a recent serious discussion (read: rants) and lack of platform developments, it's been decided that Commander X16 will no longer be the main target system. However, a new one is planned and I already learned its CPU architecture 😉

Chat I accidentally bought two of them again

Also here are funny bugs compilation during the development of this #nesdev

Meanwhile you can enjoy the 90% done party version of Otomata Labs' NES demo here! Which won 3rd at Revision 2025 oldschool demo compo! demozoo.org/productions/... #nesdev

Good morning! I'm currently finishing up something for tonight's demo compo. Please look forward to it!

Today we discovered that in early 2C02 PPU revisions, there's a hidden test register that puts in a special video mode where all 64 colors are accessible! Sadly we're still figuring how to reliably access it and the only proof was this low-quality image... #nesdev

"As you wish, master! I can also do other kinds of housework for you. Except cooking though..."

"Hi! Who do you want me to turn into today?"

Recording a raster seismograph using Mesen scripts #nesdev

If you have difficulties reading Katakana, just remember this:

wtf How did this got nominated, it only has random lines and a banger music 😳

Oh no I accidentally discovered the reverb fart patch for OPL2

Advanced technique: using an interrupt to record a current loop counter value and then modify the return address to exit earlier

Happy new year! 🐍

Oh no I'm deliberately removing a pre-painted decal

Did you know that MMC5 also has a feature called vertical split where it can switch tilemaps mid-line? Turns out it's possible to make SNES-style shaped windows out of this by changing split position each line! #nesdev

Where we're going, we don't need FPGAs. #nesdev

I got all raster interrupt codes done for the textbox. Sadly due to a very wide latency window from DPCM DMA, I couldn't get all 64 sprites intact. But I don't think I'm going to use all of it anyway 🙂 #nesdev

Hey, finally a dev progress post! Right now I got basic splits working. The textbox still needs more interrupts to alternatively show the bottom half of the font. #nesdev

As the year comes to an end, I looked back at all the stuff I did and posted. I realized I did so little that it's not good for me. So my goal for 2025 is to have all my work at TWO HUNDRED PERCENT!!

So today I have to turn this into assembly

I made a font for my game

I ported @64abstract.bsky.social 's Carve Your Own Path to MMC5, totally not going to use this to test something 😉

My friend did a chill remix of my hit song, please check it out!

very wip remix(??????????????) of #1f1e33 by Camellia . Extremely Loud , be cautious when playing #dtm

I found another use of this now. Just need less compression and higher sample rate. Hm I don't remember being able to pitch DPCM this smooth 😳

Making a new DPCM tech (sadly only works in very few mappers)

I decided to do another big sidequest The code name is Project OZOne

Alright, here's an actual introduction 😅 Some of my interests are: - Old computers - Demoscene - Game dev - EDM (esp. chiptune) - Hololive - Figures & model kits - Cooking I helped Furnace dev and made a compo-winning song youtu.be/pOB5qR2qf_c Also I draw too! Here are some of my best below
