Dualis NDS ROMs

Nintendo DS emulators (even ensata) are far from being perfect. Mostly you can use Dualis emulator to play homebrew nds roms, but there is a number of commercial Nintendo DS games that can be fully or partially emulated with it. On this page we have posted an extract from the compatibility list as well as linked to the full list that is compiled by humantree at blacklisted.ivgdb.com. Don't expect the compatible nds roms to run at full speed.

Little note from Imran (creator of Dualis emu)
Dualis is not able to run dumps of NDS cartridges. Do not ask me if/when it will be able to run said dumps.
Also, do not ask me how/where to get non-public material concerning the DS.
If you didn't understand the last three sentences then get the out. Thanks.

We don't provide commercial DS rom downloads. If you are looking for romz to play with nds emulator go to Nintendo-DS-Roms.com where you will find full romsets and separate game files. (You have to have eMule for their download links to work).

NDS ROMS compatible with Dualis emulator

Notes on GBAMP emulation.

The directory of the ROM that you are running is considered the root directory. It and its subdirectories will be scanned recursively for files when the ROM is loaded, and whenever you reset emulation. The emulator only supports read-operations, so creating new files and directories from witin the ROM is not possible. File date/time data is not available. The limitations of the FAT are as follows:

Max total number of files/directories: 32768*
Max number of files/directories on the root level: 512* Max total file size: 256 MB *
The numbers specify the number of directory entries. Files that use long filenames require more than one directory entry - thereby reducing the possible number of files.

Write operations are limited to creating and writing to files. Directories can not be created. Nor can files or directories be deleted. All newly created will be created in the root directory no matter what path you specify. Newly created files can usually not be read from without restarting the emulator. The data that is written to a file will be the same that is written by the FAT library. That is, even if your program is only writing a single byte to a file you will still end up with a 512-byte file since an entire sector is written internally.

As you can see DualiS is best used for homebreew nds roms and commefcial ds roms can not be played using this emulator.
Notes on main memory (display fifo) mode. The display fifo is at this point not emulated accurately in respect to the hardware. Instead what happens in the emulator is the following: When display fifo mode is enabled in DISPCNT, at the beginning of a hblank the GPU sends a request to the MMU checking for a properly set up DMA channel (word count=4, repeat on, fixed dest, etc). If no such channel is found, nothing is done. If such a channel is found the MMU will return the DMA source address to the GPU, which in turn copies the data from that address (offset by the current scanline) to the virtual screen. There's no delay until the next frame starts, as would be the case on a real DS.
