@voljega Totally correct, the same for me... Spending 90% of my spare time collecting, scrapping and organizing games, 9 % of my time just looking at recalbox running and 1% of my times playing... (and always the same game, otherwise it wouldn't be fun XD )

Edit2:
I solved my problem.
For anyone else who has similar problems with switching from an onboard bluetooth to a second usb bluetooth dongle:
editing 'recalbox/etc/udev/rules.d/81-bt-power.rules' did the trick. I changed Kernel=="hci0" to "hci1" and after a reboot the usb dongle powers up.
I am not sure but it's maybe necessary to additionally switch /update the default agent via bluetoothctl. Afterwards controllers can be paired manually as described here.

@leandro-siqueira this is a very old topic and you haven‘t made any question. I‘m closing this.

@0zzy well, keep trying, i'd be curious to see how it works afterall 🙂

oui  et ça ne fonctionne pas

Thanks for the link, clears everything up 🙂

Well if anyone read that thread : please don't do that !!! All your problems come from your downloading of random BIOS files : this files are already included in your 0.78 romset in the correct version needed by mame 0.78. Which is not the case of the ones you downloaded which can come from any mame version. If those files are not in your romset it's not a good nor complete one And it's pretty clear in the wiki easy arcade that those BIOS files are in the romset. So downloading other files and using clrmamepro is totally useless AND creating problems, like you experienced Also there's no need at all to modify recalbox.conf like you did : mame078 is the version used by default in recalbox
