@leonjordan i had a number of problems installing the openbor scriptmodules. i suggest you try RetroPie-Extra version of the openbor scriptmodule, which will install an up to date build (65xx) with ability to direclty launch .pak files without extracting them.
@zerojay The extensions were missing from es_systems.cfg in the openbor section; I just had to add them😊. It's launching now!!! Thank you so much for all your help guys. Really appreciate it.
