I've released an utility to inject NES rom files into the official NES VC emulator for the Nintendo 3DS. I used the Zelda 2 (USA) VC and Ice Climbers (USA) VC while testing this app, but any NES VC ROM should suffice. What's New? v1.2b - added Famicom Disk System 3D Banner v1.1b - added Famicom 3D Banner in addition to NES 3D Banner v1.0b - added 3D banner support (for the custom 3d template) - refined text input process - added ability to change game name, description, publisher - added ability to change the game output filename - added ability to process roms that aren't in either database - tweaked the game values editor a bit - enter in any value for the ROM mapper to explore compatibility - added more screen resolution modes Download: Here Requires .NET Framework 4.5 To convert 3DS to CIA you can read this guide and then to decrypt the CIA you can read how to in this guide. If you're interested in what this program is doing you might find this helpful. Would you like to inject SNES games? If so click here. Thanks to @ihaveamac for help with the tools used in this injector! I'd also like to shout out to @Asdolo for the much appreciated help with creating the 3D banner code as without him it wouldn't be possible! Is your ROM not working? Try this instead.
