4431 - Call of Duty - Modern Warfare - MobilizedPlease provide me some suggestions and if they are patches needed can you provide me.Cheers!

you're not providing any information. What flashcart are you using and what firmware version?

Sorry this is the very 1st time i post in forum.Nintendo DSi
Flashcart: Acekard 2i
Firmware: Ver 1.2u

Have you tried updating the Acekard's firmware to the latest version?

@slams: You'll notice that all the ROMs you listed have AP. You'll need to bypass that.Follow this tutorial and you are a-okay.1. Format your SD card using the Panasonic SD Formatter 3.1
2. Download my AceKard Package
3. Copy the files from the AceKard Package to the root of your SD
4. Run the card on a DS or DSi
5. Select the '3DS 4.0, DSi 1.44 Patch - [DS Lite or DSi].nds' from the menu
6. Follow the promps
7. Reboot your DS and then insert your AK2i into the DSi
8. Done. You are now able to use your AceKard and update to the DSi 1.4.4 firmware.This process will fix most compatibility.
If you want a bigger update:1. Download the latest Loader Package.
2. Extract and copy the files to the "__aio/loaders" directory.That will fix pretty much everything. Enjoy.

Thank you so much Aeither for the step by step instructions that really helps me. Will give it a try hope it works for me ;)Cheers!
