Been a while since I found good CRTs on the curb. I don’t want to repost on my secondary X account that did only that. I already have too many to pick and test those two.

Love to try out Friday’s latest build on low powered repurposed E-waste Chromebooks on the sofa. Relaxing

Also 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.

Here 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

The original chip has 10 outputs on its Noise Period table, while the latter one has 11.

I 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:

Aparently 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

Your yearly reminder (and first time on bsky!) that the WAVE specification's smpl.dwEnd (loop) member is inclusive, not exclusive

Needed 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!
