Nah, no first place for me this time, that was to be expected. I only had one day to spend on this, so didn't polish things up as much as I could have. So, congratulations on your well-deserved win, Shiru. Excellent work. Especially beating we with my own engine hahaha.

It was a very strong battle overall. Really like BioMech as well, that middle section with the fast arps sounds so slick. Surprising entries from AER as well, glad to hear some beeper from him again.

Excellent article, thanks. I have a hunch this lsfr trickery could also be useful for 1-bit engine code.

ATTiny would be an interesting hardware emulation backend to support in Bintracker, actually. So Bintracker could serve as an editor for greeting card melodies, haha. Perhaps that's overkill for something this simple though.

Random brainfart, maybe the 16 bits rom are mask values for some binary counter that is related to the pitch lut? ie pitch lut contains base init values for the lsfr for one octave, and the 16bit rom has something to do with selecting an octave.

The pinnacle of modern 1bit music. Fantastic compositions with a very distinct and recognizable style, and an incredible amount of polish. Who'd have thought something like this was even remotely possible back in the late '00s.

Thanks for the information. Unfortunately it's a bit hard for me to follow zx-pk.ru, as google translate does not do a very good job translating the mostly informal language used there.

Is the 8080 source code available for these ports?

Also, first time I hear about Lvov PK-01. Found this emulator, is it any good?
EDIT: nevermind, seems it's also available in MAME. Hard to find documentation on the machine, though.

Meh, that's pretty bad news. But great you figured it out, thanks a lot for your efforts!

So basically any engine that doesn't mask bit 3 will be incompatible with the +3. Which is like, most of my engines So I guess you better stick to Shiru's engines for now.

Very odd. This should toggle the border color every scanline, but seems it's actually running much slower?
Admittedly I'm pretty much out of ideas, so let's wait and see if Noel will be kind enought to run some tests.

Damn. Could you try the attached .tap and post an image of the screen? Probably won't tell us much either, though.
You don't happen to know any other +3 user who could test this on their machine?

Yeah, that looks a bit nicer for sure Care to make a pull request on Github, with the updated fritzing file? Or, if you can't be bothered, just attach the .fz here.

I can't comment on the headphone amp, since I didn't make that. You'd have to get in touch with @salkinitzor. I can confirm it works, though

Ok, so what's the current state, you got things rolling on the 83+ but not on the 83?

Problem is, there was no Windows 10 when this stuff came out. And then Microsoft made damn sure things will be hell for 3rd party devs who need access to lo-level stuff and don't want to pay $$$ for an agreement with them. Anyway, to make your current setup work with TiLP,  you need to carefully follow all the steps in this guide: https://github.com/debrouxl/tilp_and_gf … ADME.win32

Now that is also beyond me, lol.

xxl, what is the timing for the interrupts? If we had some fast interrupt reset CONSOL each scanline, for example, then this could actually be useful for PCM/pulse-interleaving playback.
