don't use the "hacked" emulators included with the firmware. just use goomba color.

-another world
I followed the instructions and created a compilation containing Pokemon Red, Blue, Gold, Silver, Yellow and Crystal. I created the gba file in the goombacolor directory and copied that directory onto the sd card. Started the gba file (emulator is goomba color 12-14-14) and started Pokemon Red. Played for a few minutes and saved. A save file has been created, but when I start Pokemon Red again I only have the choices "NEW GAME" and "Option". No Option to load an old save. So in that regard Goomba Color behaves like PocketGBC 2012 that the REVO K101 comes with.
