Okay. Many of you know the DSTWO+ flashcart. It is an enhanced flashcart for DS games that has the additional function: it can emulate Gateway to play .3ds roms. Some of you were (un)lucky enough to get this one. There's a problem, however: some of the latest launchers (3.5 and so on) have the detection of counterfeit carts ("brick code", 3.6+ ones don't even allow you to select games) making it seemingly impossible to play games on DSTWO+ with the latest EmuNAND. But there's a way to fix it and to make 3.4.1 launcher work with 11.0 EmuNAND. Unfortunately, this method only works with Old 3DS/2DS (no new ones, 3.4.1 doesn't support 9.6+ New 3DS EmuNAND) It is advised to back up EmuNAND before making such modifications. What do you need: An EmuNAND set up on your 3DS/2DS (with Gateway CFW or with any other CFW) FBI ver. 2.0+ installed on your 3DS/2DS in EmuNAND 3.4.1 Launcher.dat (if you own the DSTWO+, you probably know where to find it) A hex editor of your choice 1. Get the Home Menu title: go to "that iso site" and find the topic with the downgrade packs. Download the 9.9.0 one for your region and then find this one title. It should be 0004003000009802 for EUR, 0004003000008F02 for USA or 0004003000008202 for JPN consoles. 2. Open the hex editor and go to offset 0x2F9C. Change 2 bytes to FF FF (to change version number to 65535). This way you can avoid Home Menu updates. Alternatively, you can change the bytes to 60 00, 64 00 or 6C 00 for EUR, USA and JPN menus respectively to safely update EmuNAND in the future without the fear to screw it up. Save the modifications. 3. Place the 3.4.1 Launcher.dat in the root of your SD card and modified Home Menu somewhere. 4. Launch EmuNAND from CFW of your choice. Make sure that you have FBI installed on your EmuNAND. Go to the system settings and update EmuNAND. 5. Launch FBI and then install the modified Home Menu. 6. And there you have it! Now your DSTWO+ can launch .3ds roms on 11.0 EmuNAND! (tested on European Old 3DS) Online play? Works! A9LH Payload? Stage2? 3dsx? Everything works with 3.4.1!
