OS v1.10 has native support of goomba and pocketnes, you don't even need to make emulation packs, cart can run .gb, .gbc and .nes files right from menu and loads emulators on the fly
Hot-diggity!

I am curious, for those Game Boy color games that use the RTC like Pokemon, does the Goomba EMU utilize the RTC? If not that's fine, but considering the GB ED don't have an RTC, it may be useful. Not that it matters much since the Pokemon games are partially broke on the GBA X5 considering they reset the RTC for all games each time you start a new file on one of the ROMs.
EDIT: I added Goomba and PocketNES. I booted up "WarioLand 3 (World).gbc". Worked great. Played through the intro and saved. Power off GBA. Restart and progress was not saved...

EDIT2: Red light on X5 does not flash when saving to SRAM in game using Goomba. Hit L+R to access menu and manually save current state. The red light on the X5 flickers showing that data was recorded. Next time you load the Game Boy or Color Game, it will start with current SRAM, even if you never actually resume from the save state you created. You must save state from the Goomba Menu to record your progress...

EDIT3: Auto save / auto load option from saving sub-menu on NES games is buggy. Do not use. You will crash the game and boot into an unrecoverable state. Delete save using PC file manager and start over...
