pif_rom_dumper

This will dump the PIF ROM to SRAM, where it can be easily read.

To use:

1. Load and run the pif_rom_dumper.n64 ROM on a flashcart / backup device / ROM emulator. See below notes for Everdrive 64 and 64drive.
2. When the onscreen instructions appear, press the console's Reset button. It should briefly say "Pre-NMI" and then reset.
3. A message should say "Saving to SRAM..." and "Ok!". You can now turn off the N64.
4. Extract the first 0x7c0 bytes from the SRAM save, this is the PIF ROM.

Notes for Everdrive

When you successfully run the dumper, a save file called pif_rom_dumper.srm will be created in the ED64\Saves directory.

The save type is specified in the header, so it should no longer be necessary to modify save_db.txt on Everdrive. For historical reference, this was once done by adding a line in the CRC detection section:

0x5716C25D=3 (pif_rom_dumper)

Notes for 64drive

I prefer to use the command line tool to send the ROM over USB, set the save type to 256K SRAM, and then read back the SRAM directly.

If you instead want to run pif_rom_dumper off of a SD or CF card, follow these instructions:

1. Check the 64drive options menu, "Reset button action" must be set to "Game".
2. Select pif_rom_dumper.n64 from the menu. Before you press Load, first set "Force Save" to 256K.

(I'm not 100% sure this will work, I haven't been able to test it.)

When you successfully run the dumper, a save file called pif_rom_dumper.sra will be created. Depending on your settings this may be alongside the pif_rom_dumper.n64 ROM or in a subdirectory called Saves.

Troubleshooting

If you see "Save verify failed." then SRAM was not configured correctly, see the documentation for your device.
