Hello I have bought a new 3DS XL which is currently running on Firmware 4.2.0-9E. Of course the 3DS wants to update the Firmware when entering the eshop or playing new games. The problem is I ordered a Supercard DSTWO this week but the shop told me I will have to wait for at least 2 weeks cause they dont have any DSTWO available at the moment. But I would really like to play 3DS games now and buy some new ones in the eshop. Therefore my question: The DSTWO will not run in 4.5.0-10E out of the box so I need to update it. Unfortunately I dont have a DS/DSi available... Is it possible to update the DSTWO with Firmware 4.5.0-10E?? I read something about renaming the update file with a "b" on the end and then wait some minutes in the home menu. Does that really work?? Thanks in advance for your answers!
