Do not patch anything with anything except for DLDI patching the lameboy.nds file. Put the patched lameboy.nds file on your card as well as the GBC file. Turn on your DS and launch lameboy.nds, not the GBC file. It will present you with a file listing on the bottom screen, where you select the GBC file to play.
A few possible things to consider if you're still having troubles:
1. Are you sure you're copying over the lameboy.nds file and not a text file? Your image shows the "lameboy" file being openable with Notepad, which doesn't seem right.
2. You say "But the lameboy emulator cannot be find whilslt looking through the games list on my DS." This implies to me that you're running the M3 in GBA mode. You must run it in DS mode for DS programs like Lameboy to be visible. Do you have a passthrough device in slot-1 to let you boot the M3 in DS mode?Â
If you don't have a passthrough device, then you can't use Lameboy and you'll have to keep using Goomba Color. If this is the case, be sure to grab the latest goomba.gba file from

Go to the game manager program's folder in your C:\Program Files directory and find the place where the emulator cores are. One of them will be the old goomba.gba file renamed to something else (not entirely sure exactly what it will be called). Delete this one and replace it with the updated goomba.gba file, renaming it so it has the same filename as the file you just deleted.
