GBZ on retropie help.

[jermzz]

Hey guys, sorry if this is in the wrong place. There's a reteopie subforum, but I figured I could post here because it's GBZ related.

My adafruit screen won't be here for a few more days, so my build has been at a halt. But being I had all my buttons hooked up and in my case with the teensey programmed, I figured I'd setup reteopie (first time emulator user, and rpi for that matter) and get my roms installed and try out my case. So I put a few screws in it, plugged my monitor into the hdmi port of the pi, plugged the Teebsey into the secondary USB port, and then plugged the power USB port to turn the pi on.

Forgot to mention before all this I put retropie on the SD I was using, did the audrino/teensey install and verified all the buttons were working by plugging the teensey in and pulling up notepad.

Anyway, pi boots up and into Retropie..... And then it tells me that it can't find any game pad.

Curious, I unplugged the GBZ, and plugged in a normal USB SNES style controller and rebooted the pi. Same thing, no game pad.

Only two things I can think of is, maybe I need to use a powered USB hub, which I don't currently have.

That, or there's may some configuration to reteopie that I haven't done for it to work with different game pads. I read somewhere about using ssh to edit config files, nothing in depth though.

I was following the documentation on the Retropie website and it doesn't account for this. Nor can I find much insight online about this specific issue with the pi zero.

I don't need a hand hold, if someone could just point me in the right direction, I can figure it out.

Thanks for any input in advance.

Silly question but did you try holding down a button after emulationstation starts up? It'll have you go through a setup for what buttons do what. Holding a button down for a few seconds when it starts up and is showing that prompt identifies what it should use as a gamepad.

It does show the screen where it asks me to press a button to recognize the controller. I tapped some buttons with no avail, but didn't "hold" a button down longer than just a tap. I guess I can try that when I get home. Is that standard procedure for Retropie?

Yup! Give that a try.

Yup! Give that a try.

So that didn't work, but I did end up getting it working.

Power was the issue. I guess the pi zero doesn't provide power natively to the secondary USB port. I ran an OTG cable and gave the USB power and the GBZ and then emulation station recognized it immediately.

Ah interesting. Glad you got it working.

Totally did! Can't wait for the screen to get here.

Thanks for the help let me pick your brain on one other thing regarding the SD card. I bought one of kitsch-bents cartridges and I'm having trouble wiring it up to my pi. It seems he calls that data_in and data_out test pads should be used to hook up the Sd card. Which is 22 and 23 respectively on the pi. It seems rather that you use those pads for USB.

he has a diagram for wiring on his website with the product but many names don't match what is on many Sd pin diagrams I see. Vss, data_in, data_out. I was assuming that was D+ and D-. But I can't get the pi to turn on with the Sd inserted in the cartridge slot. Can you verify for me at the least that the test pads you use are the only ones that should be used for the pi in its default configuration? All these SD card voltages and symbols make my head spin.....

Thanks again wermy. You more than go out of your way to help us out.

Dat in and data out are pads 15 and 16 for the ad reader I think. Try that and see if it works

Okay. That wiring worked. Thank you. But now I'm getting kernel panic. "Kernel panic - not syncing. No init found. Problem after problem. The Sd card still works when put directly into the pi.

I was having the same issue with the panic. I tried a different SD card, different brand and size, and it worked fine.
