It cost {{Inflation|USD|169.99|2009}} at launch and later dropped to {{Inflation|USD|149.99|2010}}. The system, however, was region-locked, meaning that DSi exclusives from different regions couldn't be used and the system language couldn't be changed. It also did away with backwards-compatiblity by removing Slot-2 which was used to load GBA cartridges and other gaming certain accessories (''i.e. Guitar Hero: On Tour''such as the Rumble Pak).

There hasn't been much of a need for DSi emulation has been pretty neglected due to it's its small library of exclusive games and lack of DSi-enhanced titles that provide anything major besides camera support. The only thing really notable is DSiWare, which saw several exclusive releases.

No$GBA added support for DSi games of all three formats starting with version 2.8, although some games won't boot and others have graphical glitches. You'll need to enable ''"16MB DSi/retail"'' under the settings in order to use it. Compatibility is very iffy due to No$GBA's already poor DS emulation, and the camera is just spoofed as a static image and will causes cause the emulator to crash whenever used, meaning games that uses it may boot, but won't be very playable.

DSi used an encryption system for the game dumps that went on to be enhanced and used for the 3DS. This encryption is checked at start-up, hence why Nintendo DS emulators don't even manage to boot DSiWare dumps. It's very unlikely DSi-mode emulation is ever going to be implemented in DeSmuME in particular due to various ''creative differences'' unique to that project. melonDS recently started attempts at DSi emulation and has been able to boot the system's firmware<ref name="melonDSi">http://melonds.kuribo64.net/comments.php?id=94</ref> and even showed that it can boot ''Flipnote Studios'', but freezes when attempting to create a new note.<ref name="progress on DSi">http://melonds.kuribo64.net/comments.php?id=99&p</ref>. It's being worked on off an experimental branch and requires a lot of files to be dumped from the DSi in order to work, but it could become the most usable option for DSi emulation in the near future. Most of it is being done using the documentation that the No$GBA devs have already compiled on the subject. For now, it only supports DSi-enhanced regular DS releases.

All three formats can be converted to <code>.nds</code> format. Compared to regular DS games, DSi games have some additional header information that wasn't even correctly dumped in most early sets. The 2017 set has Recent sets have since updated many of these to the correct format, though it's still severely lacking in DSiWare exclusives. DSiWare dumps can exist in both <code>.nds</code> format and <code>.cia</code> format (for installation on a homebrewed 3DS).

On the DSi/3DS family of handhelds, the first two formats can be played on some select DSi-compatible flashcarts like the discontinued and expensive CycloDS iEvolution flashcart(which won't work on a stock 3DS unless you install custom firmware to whitelist it). As for the third type, some are only available for digital purchase at the 3DS eShop and are installed as apps to the limited TWL NAND. Users with custom firmware can also convert DSiWare to an installable <code>.cia</code> and even dump already installed ones back to <code>.nds</code>. Since the DSi Shop has closed, the only way of obtaining DSiWare on the physical system is by [[Modding Consoles/Flashcarts#Nintendo_DSi|homebrewing]] your DSi and either [https://dsi.cfw.guide/installing-dsiware| installing] it to the system's NAND, or launching the <code>.nds</code> ROM through Unlaunchor [[TWiLight Menu++]].

DSi emulation requires a copy of the lower 32K-halves of the ARM7/ARM9 BIOS files (<code>BIOSDSI7.ROM</code> and <code>BIOSDSI9.ROM</code>), which are different from the regular DS BIOS files and needed for the decryption. All melonDS also requires these files along with the regular DS BIOS and the needed files are <code>bios7i.bin</code>, <code>bios9iDSi's firmware.bin</code>, <code>BIOSDSI7.ROM</code>, <code>BIOSDSI9.ROM</code>, <code>BIOSNDS7.ROM</code>, and <code>BIOSNDS9.ROM</code>. These unicorns can be found [http://archive[Emulator_Files#Nintendo_DS_.org/details/DSiFirmwareFiles 2F_DSi|here]].

It's also advised (but still completely '''optional''') to use a NAND dump as well for No$GBA to increase compatibility (though adding games is more complex, and however a soft-modding solution to NAND dump it is still being worked on). Rename it to "DSi-1.mmc" (should be about 250MB). In No$GBA, change ''"Reset/Startup Entrypoint"'' to ''"GBA/NDS BIOS"'' to now boot the emulator and games in DSi mode. Hex editing is required in order to "install" new DSiWare titles. Using a NAND dump fixes a lot of glitches and crashes related to languages and use of the internal DSi fontmelonDS.
