Dragon Quest Heroes: Rocket Slime/Notes

The following article is a Notes Page for Dragon Quest Heroes: Rocket Slime.

Save Files

Save files are divided into two main sections:

• hiyama - main section with most data (items, monsters, tank info, etc.)
• nabeshima - smaller section whose purpose is currently unknown

This naming scheme is actually used inside of the save file, with the names being present as ASCII strings. They are very likely references to the game's Lead Co-Ordinators: Kousaku Hiyama and Hiroyuki Nabeshima.

Checksum

Both the hiyama and nabeshima sections have their own checksums. Both use the Nintendo DS BIOS SWI 0x0E (GetCRC16) and start with a value of 0x11.

Section	Checksum location	Checksummed bytes
hiyama	850 - 851 (2 bytes)	0 - 849 (850 bytes)
nabeshima
