N8 compatibility with Retro Champ

Has anyone been able to get the N8 or N8 Pro to work with the handheld Retro Champ NES clone? When I try to use my Famicom N8 Pro with it, I just get a black screen. The cart works fine on my AV Famicom and it's up to date with the latest FW (v25.1123). I know that Everdrives are primarily meant to work with original hardware, so it's not a huge deal that it doesn't work with this. But would like to at least understand why it's not compatible and if it would ever be possible for Krikzz to make it work in the future or if there is just some fundamental missing functionality on the Retro Champ that will make this impossible.
