Homebrew gba exploader help

[Excitedguy]

I have Acekard 2i with moonshell and I am trying to use gba exploader to run .gba games from my acekardi sd card combined with my EZ Flash IV Lite Deluxe (not the 3in1), however it says cannot find slot 2 expansion card when trying to open .gba files, I have already tried patching the gba exploader nds with with the EZ flash IV dldi patch and no luck, can someone help me out here?
