Hello. Thanks for 7.2 version!
Same probleme since 7.0 version pesists (inverted direction controls), as described here:
https://forum.recalbox.com/topic/21871/rb-7-0-1-vectrex-contrôle-analogique-inversé/2?_=1619275483197
Solution still the same:
Extract VecX.rmp from share_init sand paste in: share/system/.config/retroarch/config/remaps/VecX/
Hope this help you.
