This contains the format for an Arcana save file. Each file takes up $500 bytes, and has a copy for protection.
They are tranferred 8 bytes at a time via MVN at $00/CAB6, which uses X= RAM address, Y= SRAM address, A= # bytes to copy
During the saving process, a ton of checksums are written by looping through the data at least 20 times.

Chip tiny.png The following article is an SRAM map for Arcana.

This contains the format for an Arcana save file. Each file takes up $500 bytes, and has a copy for protection. They are tranferred 8 bytes at a time via MVN at $00/CAB6, which uses X= RAM address, Y= SRAM address, A= # bytes to copy During the saving process, a ton of checksums are written by looping through the data at least 20 times.

File ranges

Slot 1 0100-05FF, 1100-15FF
Slot 2 0600-0AFF, 1600-1AFF
Slot 3 0B00-0FFF, 1B00-1FFF


Save file format

This assumes Slot 1. Add $0500 for Slot 2, and $0A00 for Slot 3.
