Game Boy Color Zero (GBCZ) *With Build Guide Notes

[infinitLoop]

This is great :3 miles better than the one i made a couple years ago. Didn't even have audio lel https://imgur.com/a/9tEZF

i saw that when i was researching mine still a good job!! you had to do a lot more work than i did. i lucked out with the glitch'd board having been designed for it, which was the most difficult/annoying part, i thought. plus, the pocket adventures stuff which just makes any of these builds go so much easier.

How is it?

the gameboy itself? it's ok. i prefer actually playing games on the DMG vs this, but i do like how small the whole thing is. for someone with small hands (which is not me), this would probably be ideal, but the DMG fits me better. i think for me this was more about the challenge of building it in that form factor though.

i think the smaller SPI screens perform better than the 3.2 inch ones that get used in DMG builds, which is interesting. handheld games are still a lot of fun on here, but like any of these really small screen units, console games can be a bit much to cram onto the display, depending on their UI.

Highlights:

• 2.4in SPI Screen (with ~60fps - most of it is visible, but the left side is cut off a little, with overscan)

• "Safe" Shutdown on the power switch

• 2500mah battery =~ 5.5+ hours of gameplay

• Silicon shoulder buttons

• I2S Digital Audio with Digital Volume controls

• ADS-1115 Battery Monitor

• Full-size external USB port

• External SD Card access from original power switch spot

I see you're a fan of the adafruit i2s audio.. I'm trying to get one working but cant figure out the wiring.. how'd you do it? and any other configuring other than adding it to config.txt? and the SPI screen I guess too... lol.

Thanks!!

i just follow adafruit's guide here:
https://learn.adafruit.com/adafruit-max ... p/overview

wiring guide:
https://learn.adafruit.com/adafruit-max ... -pi-wiring

Amp Vin to Raspbery Pi 5V
Amp GND to Raspbery Pi GND
Amp DIN to Raspbery Pi #21
Amp BCLK to Raspbery Pi #18
Amp LRCLK to Raspbery Pi #19

although, i found that i needed a "sudo" for the bash execute in the command they have - this is what i typically run after its wired:

Code: Select all

cd ~; curl -sS https://raw.githubusercontent.com/adafruit/Raspberry-Pi-Installer-Scripts/master/i2samp.sh | sudo bash

you can say no to the background services question - retropie doesn't use that i believe, and it'll help with performance.

and there's some more tips here if you have trouble using the mixer:
https://learn.adafruit.com/adafruit-max ... i2s-tweaks


for the SPI screen, check out the first post in this thread - i have everything you should need to set it up there in the "detailed instructions" under the software, and pocket adventures has a pretty good guide too if you want to use that driver instead: http://www.pocketadventures.com/guide_c ... screen.asp

dang, I did exactly this and still have no sound. Im so frustrated with this build Im about to drop it in the trash and start fresh...
maybe my amp is bad? idk what to do now.


Thanks for your help.

hm. i haven't had a bad one yet, but i suppose it is possible. do you get any sound at all? have you disabled the pwm audio in the config?

No sound what-so-ever. not even from the sound test using adafruit's instructions. I have tried on two prebuilt imgs and a fresh install of retropie with no different results.

[Robochris]

I just tested on two pi zeros and a pi 3. no sound on any of them.

hm. if everything has good connectivity and it's still not working, then maybe it is a bad amp. if it's an adafruit one, they might replace it for you if you contact them.

just to be sure - you used the gpio pin numbering, right? sometimes the physical pn numbers vs the gpio numbering can mess people up.

Yeah, I used the gpio pins not physical pins. I checked continuity for each wire and had 5v at power in.. It is an adafruit amp but I didnt buy from them... not sure if that maters.
