I bought an used Nintendo DSi XL off of a friend and a brand new R4i SDHS Dual Core 2015 PRO v4 card but somehow I can't make it work. I have tried multiple versions of the software from http://www.r4isdhc.hk/r4-download/ as it was noted on the site that I bought the flashcart from but none of them works or I simply can't figure out how to enable the card. When I insert the card a new game pops up called "Bomberman" and after clicking on it all it shows is a white screen with a red rectangle that says "MENU ?". The software version of my Nintendo DSi XL is 1.4.5E. Can someone help me out? Which software do I need and how do you properly install it? Is this R4 card even compatible with my Nintendo? I'm new to this Nintendo scene so I have no idea what to do.
