I know, such a shame not to integrate it
I think it would be easily possible of the official ones from chronocrash would take part and ...
i don't understand the Retropie Team
... would support a legal "RetroPie branch". I think our moderators are aware of rising support that is needed for this and indeed I can't support it because if something will fail (hardware support or whatever) on our Raspberry we are stuck and the only one who can provide better support ( @zanac ) is missing since end of 2018. Moreover OpenBOR is totally underated between other platforms so there is less awareness - but this is only my opinion.
Can we update our OpenBOR from the last source code like any emulator from Retropie ?
Yes with the scriptmodule but therefore I need to patch the files and upload them to my git. So we have a 6512-dev from Oct 2018 as latetst version on our Pie.
I will make a new patch if the 6512 is out of dev state.
Sorry for the stupid question but i break my right hand in January and stop a lot to work on computer :(
Oh dear ... hope you are well. But take this is chance work on your left hand. It's not a problem to even write with the left hand. Just a bit of training ;)
And... then you can also get in touch with 8bit mashines like, Commodore, Sinclair, Amstrad because you only need direction and one button -> Flightstick joypad ;)
