stringsort() is now a wrapper for qsort().
extlink now accepts multibyte filename thanks to Unicode support.
Directory listing is shown the same way as WinNT(8.3 lower case). <- If you  name a file all lower case in 8.3...
/nesDS.ini is used for configuration(minIni).
@----------- end   -----------@

• updates:
• Add the shout-cuts for configuration.
• Sound fixed.. better than 0.44b. Almost no noise(not the noise channel).
• sprite0y of 'per-scanline' fixed.
• h-blank interrupt handler added, which was removed since 0.44b.

0.44b

• Since the nesDS file is larger, this version is NOT recommended for those who just want to play nes games.
• Port the whole project to devkitPro, using libnds, libfat....
• Almost no update, but some figures may be worse. e.g. sound with the games that read reg4015. Some games' sounds work better... - -!
• You guys can try 'Start+Select+R+L' to exit your nesDS and return to the main menu of flash-card. On mine, it just shotdown my DS(R4SDHC with kernel1.34, no help with moonshell2 either).
• Since this version, the mem region cannot be accessed freely, be careful if anyone wants to write a patch.
• The libnds and libfat are too big... 128k around. Shit that!

Common Issue

Run the nesDS EX Edition on ideas may cause a crush, because ideas does NOT support "swi".

NOTES:All other functionality should be identical to the original. nesDS inputs now work properly on emulators. You can run the nesDS on ideas by DLDI patching it with the R4 dldi patch usingdlditool. You must then enable DLDI support for R4 under File->Properties. You can also run nesDS on desmume but you will need to create a filesystem image from some files and embed the files to the emulator (you need to use fcsr for this).

COMPILING: You need devkitARM to compile this project. If you are compiling on windows you also need mingw. On linux you will need to have make installed.

The project compiles on windows and linux using devkitARM r32 (devkitPro). To compile on windows use msys-1.0.15 (devkitPro) as well. You do not need anyhting else to comiple the project.

Compiling on windows:

1) extract devkitARM to a folder 2) extract msys to a folder 3) add DEVKITARM environment variable and set its value to the path where you extracted devkitARM, e.g: /c/devkitARM (must be linux style path!) 4) (OPTIONAL) add path to msys binaries in you windows path, e.g: c:\msys\bin (must be windows style path!)

You only need to do step 4 if you want to compile from the windows command shell. You can compile the project without step 4 by launching mingw using msys.bat in the msys folder.

5) change to the project main directory, either in the windows command shell (step4 required) or mingw then type make.

Compiling on linux:

1) extract devkitARM 2) create a DEVKITARM shell variable with the path to where you extracted devkitARM, e.g: /usr/local/devkitARM

You can create a variable in /etc/profile or in your home directory .bash_profile file as follows export DEVKITARM=/usr/local/devkitARM or just type this command in the shell before typing make

3) change to the project main directory then type make.

To delete all object files type: make clean in the main project directory

If you make changes to the emulator and want to add them to this project or if you want to join the project notify us on http://sourceforge.net/projects/nesds
