Change the save type for Kantan Ongaku Ryoku (Japan) to EEPROM 8192 
The European version and the Japanese version of the program are completely different (as evidenced, by the ROM size), and their save data structures also differ. The Japanese version uses no more than 8192 bytes of data, it is more likely to be EEPROM 8192.

melonDS


DS emulator, sorta

The goal is to do things right and fast, akin to blargSNES (but hopefully better). But also to, you know, have a fun challenge :)

How to use

Firmware boot (not direct boot) requires a BIOS/firmware dump from an original DS or DS Lite. DS firmwares dumped from a DSi or 3DS aren't bootable and only contain configuration data, thus they are only suitable when booting games directly.

Possible firmware sizes

  • 128KB: DSi/3DS DS-mode firmware (reduced size due to lacking bootcode)
  • 256KB: regular DS firmware
  • 512KB: iQue DS firmware

DS BIOS dumps from a DSi or 3DS can be used with no compatibility issues. DSi BIOS dumps (in DSi mode) are not compatible. Or maybe they are. I don't know.

As for the rest, the interface should be pretty straightforward. If you have a question, don't hesitate to ask, though!

How to build

See BUILD.md for build instructions.

TODO LIST

  • better DSi emulation
  • better OpenGL rendering
  • netplay
  • the impossible quest of pixel-perfect 3D graphics
  • support for rendering screens to separate windows
  • emulating some fancy addons
  • other non-core shit (debugger, graphics viewers, etc)

TODO LIST FOR LATER (low priority)

  • big-endian compatibility (Wii, etc)
  • LCD refresh time (used by some games for blending effects)
  • any feature you can eventually ask for that isn't outright stupid

Credits

  • Martin for GBAtek, a good piece of documentation
  • Cydrak for the extra 3D GPU research
  • limittox for the icon
  • All of you comrades who have been testing melonDS, reporting issues, suggesting shit, etc
