GamePi Zero

Thank you very much. Great job getting it compressed so small. I will be testing this tomorrow.

[srfrboybob]

Thanks it took awhile to compress almost 4 gigs to under 1 gig. The image is almost the same as mine but I also forgot to bump up the gpu mem settings. Experiment and let me know what you find.

[cruelcynic]

Works great so far. As soon as I get some replacement parts I will be wiring up the controls.

[quote=113744]Retrogame worked great for me. I followed the instructions on adafruit. https://learn.adafruit.com/retro-gaming-with-raspberry-pi/buttons

Which pins did you use for start and select?

[srfrboybob]

Should be pins 12 and 13. I matched them to the pocket pigrrl pin layout

I am a bit confused on this still. The pocket pigrrl does not have a start select. It used the buttons on the screen. For me when I was reading the guide they used 12 and 13 for up and down.

[srfrboybob]

The pocket pigrrl does have start and pause. They are setup in part of the 5 buttons below the screen. Attached is a picture from the pocket pigrrl setup that shows the pins and keys. I think I set pause up as a different key but as long as the config for retroarch is correct it shouldn’t matter.

Hi,
that’s a really nice build great job. I have just ordered the 2.8″ adafruit screen I’m hoping it will fit inside a gameboy pocket. If you don’t mind me asking what pcb did you use for the joypad?

thanks again

[srfrboybob]

Thank you. I used two original pcbs for the controls. I cut one down as small as possible with all the buttons and one down to the a and b buttons. I glued them together using super glue. If you are using a standard two button style they do sell a easy soldier board out there.

Thank you very much. I found an old broken Gameboy Pocket in Japan that arrived yesterday looks a bit small to be honest even with the other 2.2″ screen I’m testing at the moment. I may have to go with the Original Gameboy. I managed to get the scrren working with an old pigrrl image and a bit of tweaking.

I tried your img file for retropie last night and it works partially with my screen. I’m not surprised it doesn’t work fully to be honest. I tried to SSH into it and I get an error I also tried to connect my monitor to it via HDMI but the resolution is to low for my screen. So I’m a bit stuck.

Are you able to SSH into your Pi?

Many thanks in advance

[TheRoboPro]

Can I see your audio circut?

[srfrboybob]

I am able to ssh but it runs very slow. I have a Pi 2 with a screen I use to test and hardline the ssh.

[srfrboybob]

Which part of the audio circuit do you want to see? I will take pictures but I just don’t want to disassemble the entire build if I can help it

[pumpytums]

Hi,
I would like to say a big thank you for posting the retropie img file it works great with my 2.8″r adafruit screen. I just tweaked the resolution and it looks and plays great.

I found a Gameboy dmg on ebay with a dodgy screen that I was going to use as a case but I reckon I can fix it now, I picked up a rare game (Ninja Gaiden Shadow) in the bundle too so that will help fund the rest of my project. I really don’t want to destroy a working gameboy though.

Thanks again

[srfrboybob]

I’m glad I was able to help. There are still a few bugs but it works. I understand about not destroy in a functioning console. I only use broken units for these type of builds

[TheRoboPro]

I just want to see a diagram about how you did it.

[srfrboybob]

I found the image I used as a loose guide. The main exception I used a USB audio off of a Pi zero to a headphone jack I wired to the volume control

[pumpytums]

Hi,
im just about to fit the screen to my gameboy case can you explain how you change the screen aspect and size so it fits inside the window. I believe you have a 3.2″ screen so its much bigger than the DMG-01 screen hole.

many Thanks

[srfrboybob]

The adafruit 3.2″ 2616 fits very well. It has four mounting holes that have to be removed. You also have to file the left and right edges just a hair and it should fit snug. After it is in place you will need to change the overscale options. Edit the /boot/config.txt and you will have to remove the #s from the overscale lines and play with the overscale sizes. It does take time but I do not remember the sizes at this time. I hope this helps.

[pumpytums]

Thanks for the info, very versatile isn’t it. I killed my Adafruit TFT board de-soldering the header. It may be repairable some of the tracks have lifted. I wished I had looked on youtube I could have just cut the pins off. On the bright side I have a spare 2.8″ TFT screen now. They are quite cheap on Amazon at the moment.

Thanks again

Hey this is a great tutorial. My 3.2″ adafruit screen is on its way. You said it was pretty simple, but how do you set up the USB audio? And also, with your image, I can’t seem to find some of the emulators on there. Is there a way to get the n64 and gameboy emulators on it? Thanks!
