This is a sub-page of Arcana.

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.
