Nanoloop 2 should never be inserted into anything else than a GBA cart slot. GBA is a 3V system and the 5V applied by original Game Boys (DMG, Pocket, Color) may fry the flash chip which has 4V as absolute maximum rating.
For a replacement cart, please contact [email protected].
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.
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.
