15.07.2025 13:54 β π 2 π 0 π¬ 1 π 0Been a while since I found good CRTs on the curb. I donβt want to repost on my secondary X account that did only that. I already have too many to pick and test those two.
14.07.2025 22:34 β π 4 π 0 π¬ 2 π 0Yes we hang in the same discord and compare results a lot. A lot of my recordings were used in that research
10.07.2025 22:52 β π 1 π 0 π¬ 0 π 0Worked all week on a single download Linux package. Basically a series of .deb files with a script. Works so far on not only Debian-based distros but latest Fedora and Manjaro too
07.06.2025 12:55 β π 0 π 0 π¬ 0 π 0Love to try out Fridayβs latest build on low powered repurposed E-waste Chromebooks on the sofa. Relaxing
07.06.2025 12:52 β π 3 π 0 π¬ 1 π 1Just uploaded the MDFourier capture in various format here archive.org/details/rp-2...
01.04.2025 15:08 β π 2 π 0 π¬ 1 π 0Yes but that was known for a while, this is something βnewβ
29.03.2025 10:22 β π 0 π 0 π¬ 0 π 0Thereβs been literally hundreds of NES emulators written since Nesticle came out in 97. Thousands of homebrew coders and nearly as many hardware hackers have probed those things before I did, so yes I do think documenting something new at this point feels pretty strange ha!
29.03.2025 03:02 β π 1 π 0 π¬ 0 π 0With regards to my findings of today, this was exactly it! The original βsquare buttonβ Famicom contain the old RP2A03. Got another report of an old mac emulator that implement it too. Strangely this was not known by NESDEV
28.03.2025 23:55 β π 23 π 11 π¬ 1 π 0Also the internal levels of the channels do not (seem) to match the later versions exactly compared to a 2A03G setup as emulated in chipsynth FC beta. Watch this thread for more.
28.03.2025 19:01 β π 10 π 2 π¬ 1 π 0Here is the difference between the two. First you hear the 16 different long noises of the Old vs, then the new ones. Notice the difference at the start - you kind of have the impression its stuck, this is because the two values are very similar 2046 then 2034 vs 4068 then 2034
28.03.2025 18:38 β π 10 π 3 π¬ 1 π 0The original chip has 10 outputs on its Noise Period table, while the latter one has 11.
28.03.2025 18:27 β π 2 π 0 π¬ 0 π 0The old 2A03 was used in the Donkey Kong 3 and original Punch Out Arcades, the VS series and the very first batch of Famicoms sold (the buggy ones). Lets see if any of those games used the `$F` noise...
28.03.2025 18:16 β π 5 π 0 π¬ 1 π 0I was recording the @artemio.bsky.social / @pineight.com MDFourier test on it and, it sounded very odd in the LONG noise section, not ONLY in the short noise (which is not present at all). Did Saleae 1.79MHz captures and yes I was not imagining things:
28.03.2025 17:58 β π 8 π 1 π¬ 2 π 0Aparently I just made a rather important discovery about the old (letter-less) RP2A03. Lidnariq (NESDEV guru just confirmed from die shots) essentially the lowest noise period value is different: 2046 instead of the 4068 in later revisions. This might change how certain sound effects sound
28.03.2025 17:54 β π 75 π 23 π¬ 4 π 1Thanks to a fellow dev, the archive is now on archive.org/details/RIFF...
25.03.2025 16:05 β π 1 π 0 π¬ 0 π 0Your yearly reminder (and first time on bsky!) that the WAVE specification's smpl.dwEnd (loop) member is inclusive, not exclusive
25.03.2025 15:53 β π 6 π 0 π¬ 1 π 0Thanks for the early 2000s flashback. Removing that old stinky scary monster in my basement was the first item on my list after putting loud music on when we got our house. βBut but the warmth is much more cosyβ was the argument then. Replaced it all for electric with no second thought.
10.03.2025 10:12 β π 0 π 0 π¬ 1 π 0Made a new high sample rate DC recording of the NES MDFourier test by @pineight.com and @artemio.bsky.social
Here: archive.org/details/mdf4... This time with the original DC voltages intact.
Its an ancient first generation MAudio MTrack. Old AF but its ADC is incredibly flat and doesnβt colour any range. Its The MDFourier reference.
25.02.2025 11:05 β π 0 π 0 π¬ 0 π 0Sounds like my issue. Turning all the USB power suspend suggestions didnβt help. The device worked perfectly in 23h2 and still does in on another machine
25.02.2025 11:03 β π 0 π 0 π¬ 1 π 0Microsoft can sabotage itself pretty good. Resisted upgrading to 24H2 as long as I could muster its nags. Caved in and no less than 3 MAJOR issues happened: My main USB audio device randomly starts and stops (pop-ing my speakers), WSL2 had to be re-installed and Sandbox has broken DNS. Good job.

13.12.2024 19:16 β π 0 π 0 π¬ 0 π 0Needed to do fresh recordings of the MDfourier test on a PAL NES, so popped up my new kickstarter copy of www.kickstarter.com/projects/122... for a spin (its contains this test among many other great things). Having your name and backer number written to EEPROM is a very nice touch!
13.12.2024 19:12 β π 3 π 1 π¬ 1 π 02024 was a pretty intense year for the team! We are now ready to announce that sforzando and all chip plugins will be supported natively under Linux in the future and at no extra cost to current users. Expect betas in Q2/2025!
26.11.2024 19:26 β π 58 π 9 π¬ 6 π 0Is this any better forever? I mean tired to move
