Ortin: IS-NITRO management program

GS-ORTIN-MANAGER

What is ortin?

Ortin is a utility based on reverse-engineered documentation for the Intelligent Systems IS-NITRO-EMULATOR development kit for Nintendo DS.

Portions of Ortin are based on NitroDriver by @Dirbaio.

Features

  • Set AV mode on all IS-NITRO-EMULATOR systems, including those that don't have the Video option enabled.
  • Load a Nintendo DS ROM image. Both encrypted and decrypted ROM images are supported. (Decrypted ROM images are re-encrypted on the fly.)
  • Boot Game Boy Advance cartridges by enabling Slot 2 and resetting the system.

TODO

  • Dumping Slot-1 and Slot-2 cartridges on the PC side.
  • Dumping system firmware and BIOSes.
  • Graphical interface with fancy ROM loader.
  • Implement more of IS-NITRO-DEBUGGER's functionality.

Notes

  • IS-NITRO-EMULATOR systems cannot boot from Slot-1 cards directly; instead, a ROM image must be loaded onto the EMULATOR board, which usually has 256 MB RAM. This makes it impossible to load 512 MB games. Currently, there's no known method to detect the amount of installed RAM, so 512 MB games might look like they loaded, but they will likely crash once they try accessing data past the 256 MB limit.
  • IS-NITRO-EMULATOR does not emulate Slot-1 save memory. Most games will show an error message if the save memory is not present. To work around this, you will need to insert a Slot-1 card with a matching save memory chip before loading the ROM image.
