Can't exit out of games to main menu or save games

sirdevin

@pjft If the "Emulation Station" controls are these ones (http://www.emulationstation.org/assets/featurettes/full/controllers_cropped.png), then yes that is fully set up.

I've selected the "Update Retro Pie Setup Script" option from the Retro Pie Setup menu and am still having the issue. Do I need to select "Basic Install" again or something further?

sirdevin

@CodeDrawer is there a certain terminal command to reboot?

I have the keyboard plugged in and pressing F4 doesn't do anything. I have the same movement and button controls like I did with the controller but nothing else.

pjft

@sirdevin yeah. At the end there's a new option for setting a hotkey. Make sure you reconfigure them and explicitly press select on that entry. See if it helps.

CodeDrawer

@sirdevin Yes the command is sudo reboot
then hit enter

sirdevin

@pjft That was it! I think that was user error as I assumed that the "Hotkey Button" in the mapping was for the silver Xbox button or something as I thought that every one of those entries had to be a different button.

SOLUTION for future people with the same issue: When you are mapping your buttons on the Emulation Station controls (which I posted a link to a picture above if you are unsure which controls menu I may be talking about), you have to make sure that the "Hotkey Button" in that menu is mapped to Select on the Xbox controller.

Thank you @pjft and @codedrawer for your help!

Ok, going to reopen this.

I fired up Donkey Kong 64 and despite running really choppy and slow, the same Right Shoulder + Select combo doesn't save the game. I can Select + Start back to the main menu, but can't save. Is there a different thing I have to map for the N64?

CodeDrawer

The problem is that you might not have over-clocked your pi.

sirdevin

@CodeDrawer Yea I havent touched anything with the over clocking. So I'm guessing that's necessary for N64 games to run properly? Even on the Pi 3 with the Quad core processor? Although it may not be utilizing all of the cores.

CodeDrawer

The pi 3 not overclocked is the bare minimum. Overclocking helps make it less choppy. You get that with every game really.

CodeDrawer

Normally you can type sudo raspi-config to change the overclock. BUUUUUUUUUUUUUT the raspi 3 won't allow it. But there are still ways to overclock the pi 3. I'll find it just one sec.

CodeDrawer

http://www.jackenhack.com/raspberry-pi-3-overclocking/ @sirdevin The biggest thing is, is that you need heat sinks.

sirdevin

Ok, good to know. I have an i7-5930K gaming rig that I've wanted to play around with the overclock settings. It's liquid-cooled so I believe that will allow me more room to overclock safely. I know overclocking for Windows computers can be a bit tricky and so far I haven't found a good resource for information about properly overclocking and what to look for. Do you or anyone else know where I could find more solid info about PC overclocking?

And yea any info that you have about Raspberry Pi overclocking would be greatly appreciated. Thank you so much!

CodeDrawer

Don't worry about windows. I'll help you through to get the pi 3 overclocked.

Here is a better reasourse. https://github.com/RetroPie/RetroPie-Setup/wiki/Overclocking

CodeDrawer

Right from the github page :

Manual Overclocking

All Raspberry Pi models can be manually overclocked by editing /boot/config.txt and rebooting. Read the SSH page if you are not familiar with editing text files in Linux.

Parameters are set like:

parameter=value

For example, to set the ARM to 1000MHz:

arm_freq=1000

Useful Parameters

The following speed parameters can be set:

arm_freq - speed of the ARM core
core_freq - speed of GPU processor core, keep it the same as gpu_freq
gpu_freq - speed of all GPU components, keep it the same as core_freq
sdram_freq - speed of SDRAM
sdram_schmoo - a set of SDRAM timings

The following voltage parameters can be set:

over_voltage - voltage of ARM and GPU
over_voltage_sdram - voltage of all SDRAM parts (c, i, and p)

The voltage starts at 1.2V and adjusts up or down in 0.025V steps. 0 is equal to 1.2V, the minimum -16 is 0.8V, and the maximum 8 is 1.4V. Voltage starts to help when running core/GPU/SDRAM at or over 500MHz.

To set voltage greater than 6 you must set force_turbo=1 which voids the warranty.

CodeDrawer

But @sirdevin I can get you editing that text file. Just know what you're doing! :-)

sirdevin

@CodeDrawer Awesome thanks for those links. I could just use my Cooler Master V8 and throw some thermal paste on there and call it good haha XD

I don't think I have any heat sinks laying around that would fit that. That may be a project for a later date once I've gotten some of the other parts working as I def do not want to burn out my Raspberry Pi.

I'm assuming I can just edit the text file with Notepad++ or something right?

CodeDrawer

@sirdevin I was thinking you could use the pi from terminal! :-D

sirdevin

@CodeDrawer through PuTTY or something?

CodeDrawer

So what you do first is type

cd /

that brings you to the root directory.

then type sudo nano /boot/config.txt

then you will be using the text editor! :) That should be it. If there are any questions, let me know!
