Added Stock Games do not always add the meta data in its latest form.

Seen most clearly with GBA, and the v1.2-v1.3 “sram_file_size” change.

Add Metroid Fusion, Super Mario Advance, or Super Mario World: Super Mario Advance 2 to a v1.3 database, and the “sram_file_size“ values will be null instead of 8192.

Fixed.

Just need to change some code to use the Key value instead of the Code value.
