First please bear with my english. I'm sure many of you knew or have heard of the clonning method in the first two generations of our beloved game, Pokemon, on GB and GBC. And I'm sure many have tried but failed to do the same trick on Meboy, just like me. But I tell you this, it's actually possible! I discovered this on my own a month ago. If any of you guys know this already then please let me know. Note: when I say 'SAVE' I'm talking about the save button in the actual game, and I will use 'SUSPEND' for the Meboy option. So here's how it goes, first SAVE the game in front of the PC, then deposit the Pokemon you want to clone(you can also attach an item you want to clone). Now SUSPEND the game while still accessing the PC, then change box. When the 'SAVING DON'T TURN OFF THE POWER.' appears, quickly press option and exit. Go to 'start game' and continue the saved game. Check your party and box if you succeeded in cloning. If not, just exit the game and go to 'Resume' and select your suspended game and repeat the process until you get it right. When you succeed on cloning a Pokemon, SUSPEND the game so that it will be accessible in the Resume menu.
Personally, I reset the frame skip to normal (3) when cloning so I can time it easier. And I wait for the 'SAVING DON'T TURN OFF THE POWER.' message to fully appear and then exit the game half a second after the dot.
You can also apply this trick to get all three starters, just be sure not to save in front of the pc but rather before you receive your starter.
You can also use vitamins and TMs on the pokemon you want to clone, so that when you succeed in cloning, the pokemon in the BOX has all the benefits while still retaining the used items in your bag.
I hope this made sense to you guys. Pardon my poor english.
