I've seen alot of people asking how to get this on their device so I thought I'd just make a thread for it.
I'll try and make it as simple as I can:
1. Download MeBoyBuilder.jar you can find it here
arktos.se - MeBoy (You must have Java installed for this to work)
2. Run MeBoyBuilder.jar, and hit
Add Game, and go ahead and add whatever games you like (They must be ROM files) You can find some here
CoolROM.com - Gameboy Color / GBC ROMs - A
3. After you have added the ROM, hit create MeBoy.jar, it shoud create 2 files, MeBoy.jar, and MeBoy.jad you can go ahead and delete MeBoy.jad
4. Next connect your Blackberry to your computer and find it in My Computer, it should show up as Removable Disk.
5. Open up the Removable Disk folder and drag MeBoy.jar right in there.
6. Remove your BlackBerry from your computer, and go to the
Media Folder on your device.
7. Hit Menu and then
Explore.
8. Next hit Media Card and then MeBoy.jar it should now install MeBoy to your device.
9. After it has finished you can find MeBoy in downloads.
10. Enjoy!
