I've got 2 problems:

1)I'm playing Pokemon: Fire Red on the VBA,version 1.7

WHen I try to save he game,it says: "SAVE ERROR. PLEASE EXCHANGE THE BACKUP MEMORY"
So I've been saving in the 'state'. What do I do to save normally?

2)I've just downloaded POkemon EMerald,Leaf Green and Sapphire. When I try to open any via VBA,it says
"Unsupported BIOS function bc called from 0800000. A BIOS file is needed in order to get correct behaviour."

Please search the board for Haldrie's tread(s) about this.

EDIT: Had you bothered to read through the thread directly below yours, we probably wouldn't have this conversation.

I dont think it deals with my problem of opening Emerald/Sapphire.
Anyways,I'll look through them. Thanks,and sorry for the inconvenience.

Haldrie's thread offers general advice/help and that usually helps for most games, Emerald/Sapphire being no exception.
