How DS Emulators work
How to open and play .NDS ROMs with an emulator
This works in all of the emulators.
- Firts open the emulator
- from inside the DS emulator look for File -> Open ROM or simple File -> Open option at the top menu bar.
- Slect the .nds rom you want to play and click the Open button.
- PLAY the Game!
* iDeaS emulator will require you to click a > play button at the top to Start Emulation
* No$GBA menu asks users to "Insert Cartridge.."
by that they realy mean for you to select a rom file, as inserting a DS game cart directly into a PC is rather pointless. (there are USB adapter for DS cartridges but they are for making backup copies and not compatible with PC emulators)
How we got from playing NDS roms from GBA cartridges to R4DS cards like SCTWO
Before you download DS Emultors and NDS roms I would like to warn you that NDS Emulator compatibility with roms at this time is not perfect and most likely will never be at 100%. The best emulator for NDS is No$GBA, but playing NDS romas from a Flash Card i still the best option!
There maybe more compatible nds roms as new versions of the rom emulators are released so check compatibility at NDSemulator.com website : DeSmuME / Ensata / iDeaS / Dualis / DSemu .
The very first DS Game Backup Flash card that was compatible with the DSi was the R4i SDHC, and this was manufactured for the market of homebrew. Some time in 2009, during the year’s second quarter, after Nintendo’s release of the DSi, the card was introduced to the market. It had similar functions to that of the former kinds of cards for the DS. This even included a support for the 32GB Micro-SDHC. Through DS Moonshell Media Player user was now able to play various kinds of media, and the updates for the software may now be updated frequently.
During the last quarter of the month of July, this year, 2009, DSi cards were disabled for the mean time, when there was a release of the firmware for DSi. There were a lot cards, like for instance the Acekard 2i, as well as EZFlash, were now capable of patching so that it would now be compatible with the updated firmware. But, unfortunately, it was not possible for the R4i SDHC to do so. Due to this, cards in this form were not used for the console DSi.
In connection to this, the situation made its manufacturers think twice about how the issue may be resolved, and how they would have the means to come up with a card that was compatible.
