Sideloading is now possible on the iiRcade and those in the community still trying to keep our cabs alive have created a list of games available for the platform. Any chance you could add your iiRcade APK to itch.io. If so, let me know and I'll add you to our collection of titles that the community can still purchase:

Viewing post in Montezuma's Revenge NES + Reboot comments
I replied to your Facebook post about the Director's Cut, would love to see that ported to the iiRcade to be honest (I have the Montezuma's Revenge that was ported to the iiRcade already). You can reach out to the Admin in the iiRcade Community group on Facebook (that's me) or either of the two group Moderators, any of us would be happy to help with anything we can or pointing you to people who can assist if needed getting the Director's Cut packaged for the iiRcade!
