First, take everything out of the packaging. Turn you computer on and go to your desktop. Then take you MicroSD card out and connect it to/ insert it in the T-flash (the USB port connector), and plug that into you USB port. Wait for the "what do you want to do?" menu to load and click "open folder to view files. After that, go to http://www.ishopvideogame.com/r4i-for-dsi-cid-167.html
. Search for your version and download the latest kernel version. ( the kernels are wat say "r4i version 1.4," and etc.) Once you have downladed it, if you do not have an extractor/unzip program go to http://rarlab.com/download.htm
and download winrar for you computer. If you already have an unzip/extractor program, use it on the kernel file you just downloaded. You will see a new file appear with the same name. Open the file and drag your mouse over all of the folder's contents, then right click and select 'copy' then paste them into your MicroSD card folder. Thats all you need to do, and for roms you just copy and paste them into the MicroSd card folder. i would suggest making a members account on Romulation.net, a great downloading place for roms.
