Can you install/run regular DS games from DSi mode?

Hey all, so I'm trying to setup all my Zelda games on my steam deck, and I mostly use emudeck but was having a hard time getting melonds working right with four swords, so I gave up using that and just shifted to the stand alone version of the melonds app image set to DSi. Great, works no problem. Then I go to setup phantom hourglass and Spirit tracks and just use the stand alone version too because it was just easier and I was still having issues with the emudeck version. I tried to use 2 different copies of the app image but realized it's still using the same config from the .config folder, tried to see if it would support portable but it sounds like you have to build from source and I'm not very good at messing with that, so as a last resort I am wondering if there's a possibility to install the DS roms into the NAND with the DSi files so I don't have to switch back and forth? Just trying to set this up so I don't have to tinker with emulator settings once I have them ready, just want to be able to fire them up from game mode. I don't mind scrolling and clicking the games from inside the DSi mode. Thanks, sorry for the long wall of text.
