The goal of this document is to show a complete conversion of WRAM addresses ($7E:0000 - $7F:FFFF) into SRAM slot addresses.
While many descriptions are listed (copied from here), the value of this RAMsetta Stone is in the matching addresses it contains (SRAM and WRAM), and not the description of those addresses.
It is far quicker to search for changed values in a savestate (WRAM), than it is to travel to a save point in the game to commit changes (SRAM).
For more information about the saveram checksum and other details, see the Other Resources at the bottom.
At the beginning of the .srm file, there are two bytes that are not part of the save slots. Byte 0x00 is for saving the mono/stereo (0x00/0x01) setting, and byte 0x01 is for saving the last saved slot number (0x00/0x02/0x04/0x06). These values are not covered by a checksum.
Following those two bytes, there are four save slots. The addresses in this document are relative to the beginning of each save slot.
If you want to change a value in a .srm file, you need to take the address in the SRAM column and add it to one of the following slot offsets:
| Save slot offsets in emulator .srm file
|
| Save Slot #1
| 0x02
|
| Save Slot #2
| 0x333
|
| Save Slot #3
| 0x664
|
| Save Slot #4
| 0x995
|
For instance, the Boy's name for slot #1 is located at 0x02 + 0x26 in the .srm file.
If any bytes are changed in a save slot, you must recalculate the checksum for that slot or the game will show an empty save slot.

The values below are curious. As far as I can tell, after saving your game, these values will always be 0x4F.
It seems an oversight of the game programmers, as the game copies these values from $30:4Fxx, which is open bus.
