There are two channels of digital audio. You can use them one-shot to play two samples at a time or you can play continuous stereo sound and do everything in software. In that case, the number of samples, synth voices, effects etc is limited only by cpu power and your programming skills.

afaik, the audio pin is not connected in gba. the example sounds like the pin acts as digital input or maybe it's the voltage spikes caused by mono's power consumption that get amplified.

I strongly recommend a decoupling capacitor. Mono's output on pin 31 is biased to 1/2 VCC (2.5V) so that there would be continuous current (unless there is a decoupling capacitor elsewhere in the signal path).
The +/- 2.5V voltage range exceeds standard line levels, e.g. the signal is very loud.

DMG already has relatively clean sound, noise floor is low and has a nice shape (white, slightly low-pass filtered stereo noise). For the other models (pocket, color) with their thin sound, hum and hiss noise, such a mod would make sense, but on DMG I think it's not worth the hassle.

it's nanoloop 2.

yes, it's officially licensed.

And why would you like so many TPs.

What's a TP?

It's just soft clipping with a nice curve.

yes, overdrive. maybe as an effect per channel.

TRS for now. Don't know if that's possible, but will try to include both.

please try the new version:

thank you.

I'm currently testing the integration of a mono-like analog part and various styles of LED integration. The next prototype will have horizontal orientation.

Did you press B in mGB?
When running on a nanoloop cart, mGB starts with all-zero settings so that all channels are muted, probably because it tries to load saved settings from nonexistent SRAM. To set it back to defaults, press B after startup.

mGB is only 32k, but for some reason the ROM is padded to 64k with the upper half empty. When downloading the 64k ROM to the nanoloop cart, it will boot into mGB after 32k have been received.

you need a gb color / pocket cable.

I think it's near impossible to make a Game Boy clone with decent screen today because no matching displays are available. There may be some color LCDs that have a similar resolution, but typically there is some ugly upscaling going on. Simple b/w LCDs are usually just as dark as the original ones and I'm not aware of any near-square models with a Game Boy like resolution. Memory LCDs are beautiful but screen sizes and resolutions are nowhere near 160 x 144 / 2.6 inch either. E-paper looks even nicer, some models even have an almost matching resolution but they are too slow, even the fastest partial refresh rates hardly reach 2 fps, a full screen redraw still takes seconds. OLED would be perfect, but there is a gap between small panels of up to 1.5″ and 4″+ ones for smartphones. 2″-3″ OLEDs simply don't exist. Tooling for custom displays is very, very expensive and honestly I don't think hyperkin can do that.
