There is no truth whatsoever in that quote your posting.

Unless thermodynamics have changed since i went to college a proper heatsink can’t actually make the core temperatures go up. A mistake he might have made is sticking it with ordinary double sided tape, or worse, double sided foam.

And about insulating the CPU/GPU, that’s what the black packaging with the text on it is for :)

In short: a heatsink is always a good idea, but unless you’re overclocking your RPI1/2 or running it in a hot environment it’s not necessary. They do recommend a heatsink for the RPI3 though.

Well, in his defence there were rumors and some developers already had testing boards with an NDA. :)

I believe the instruction sets are the same (32bit wise that is), so i think it should be able to run the current image.

Would love to see wifi and bluetooth on board though. I’m sure a future release would implement those.

They are files created by your mac that contain information about the real file, like time machine information or icons. Much like the famous .DS-_Store files. Your mac (and raspberry pi) hide them by default because they start with a dot.

On linux these files don’t do anything, so you can safely remove them by browsing to the folder, and giving the:

rm ._*

command, which will remove all files that start with dot underscore.

I couldn’t check it, but i believe it should be:
input_player1_b_btn = “15”
input_player1_a_btn = “14”

Also you could try
input_player1_b_btn = 15
input_player1_a_btn = 14

I’ve seen it used both with and without quotes.

You should be able to add the gamepad button mapping to /opt/retropie/configs/nes/retroarch.cfg

That should override the configs made in the /opt/retropie/configs/all/retroarch.cfg but i’m experimenting with that myself, so your mileage may vary.

Thanks, i’ll give that one a look. ’cause the situation i’m in is worse than not knowing why it isn’t working: Not knowing why it ís working :P

Just a quick add for reference, i found the attachwii.sh script started too fast on my rpi2. 9 out of 10 times the bluetooth dongle wasn’t initialized before it ran, so it gave me the “Blue-tooth adapter not present!” notification. After starting it manually it worked fine. So i added a simple “sleep 1” in the script so it would wait a second. After that, i haven’t had this problem again.

#!/bin/bash
sleep 1
hcitool dev | grep hci >/dev/null
if test $? -eq 0 ; then
	wminput -d -c  /home/pi/mywminput 00:19:1D:92:90:38 &
	wminput -d -c  /home/pi/mywminput 00:19:1D:84:EF:33 &
else
	echo "Blue-tooth adapter not present!"
fi

To be honest, i think the current layout of retroarch.cfg is just a huge clusterf*ck. I couldn’t get the same thing running. Until i found another gamepad config at /opt/retropie/emulators/retroarch/retroarch.cfg and /opt/retropie/emulators/retroarch/configs/yourcontrollername.cfg

In the end i removed all controller references from /opt/retropie/emulators/retroarch/retroarch.cfg and /opt/retropie/configs/all/retroarch.cfg and edited NintendoWiimote.cfg (your config might have another name). After that, i finally got this running the way it should.

[brainfrz]

well, that was sooner than expected. while practising my motto “if it ain’t broke, fix it ’till it is”, i actually managed to break retroarch in such a way i feel like somehow it randomizes button mapping every time i start :P

So time to start from scratch, i re-imaged my sd card, and after the essential “raspi-config” the first thing i tried was compiling retroarch from source, and this time it went smoothly.

Still curious what happened though, i’ll try to replicate my previous install (untill the point i break it) and try to find what the change was.

[brainfrz]

sorry, there was no config.log generated. i’ll try a fresh image when i have the time and report back. :) Thanks anyway :)

[brainfrz]

Thanks both for your reply, I forced the Rpi2 platform, but the same thing happens (as expected, but no harm in trying anyway)

Unfortunately, the logfile doesn’t show too much info, as far as i can tell:

Thank you for this helpfull tutorial, i got it working, but i’m breaking my thoughts over the following:

Whenever i connect my wiimote, my SSH session floods with the following message: Socket connect error (control channel)
As soon as i disconnect my wiimote, all is fine again. I can’t figure out where to start looking to fix this. i hope there’s someone here that knows how to fix this, or can point me in the right direction.

Also a minor issue, after using the above retroarch.cfg example, the buttons X and Y, and A and B were swapped. easy to fix though. Edit: on SNES only it seems, so i just added the lines to the console-specific .cfg, so i can set them up per console.

Also it would be really nice if the LED would light up to show me it’s powered on. And could i use the “home” button to go back to emulationstation?
