hi !
5 or 6 mounth ago, Ruckage, the author, said : Port is definitely coming, I've been reworking things in the retropie version to make porting to recalbox and then maintaining both in the future easier.
It's sad, but before that, he answered impatient people about time it take to make a theme without any remuneration and the few free time he had ! And it's true, I don't blame it. Work and family come first... desires too !
Maybe he had problems converting the theme due to the many differences of emulation station between retropie and recalbox
Same thing on Retropie forum, 6 days ago, a guy questions it about the update of the snes theme and he said: No, it's not dead, I've just been working on other things but will come back to this. Theme development tends to take over and use up all my free time and sometimes I just want a break from it.
<crossing_fingers> Maybe he's waiting for the stable version of Recalbox 6.0 ^^' </crossing_fingers>
