GameBoy - Tamagotchi 3 (J) Cartridge Type FD is unsupported

Hello everyone. I'm pretty much new to the forums; I hope I'm not any annoyance..Tamagotchi 3 for the GameBoy fails to load on the two emulators I use..
Well, when I first tried playing this I used the Gameboy emulator BGB (version 1.12), this comes up:

I'm not sure what FD means really. The game uses a real time clock and a speaker so you know when your Tamagotchi needs something even when the Gameboy is off:
Then I attempt with VisualBoyAdvance 1.8 Beta 3.
I haven't tried any other emulators besides the two, but I should do that now and see if any of them work...

the extra features of the cart need to be emulated (much like how the motion sensor needed to be emulated for 'WarioWare: Twisted!'), and no one has stepped up to do so (probably because Tamagotchi is not such a popular series.

Sorry, you'll have to go with the crummy U version that had none of those cool features.

Eh.. :/ GEST isn't the best emulator, but it seems that it's the only one that works with it..
What annoys me most is that the emulator pauses when it loses focus. +_+

Try messing around with settings. I know most emulators have a setting to turn on/off pausing when the screen isn't active.
