Current version: 1.2 (08-11-2016) Hello everyone. Today I'm releasing a Windows tool that will make the NES injection process much easier and customizable. I'm introducing Ultimate NES VC Injector for 3DS. What does it do?: It takes a NES backup file and converts it to an installable CIA for your 3DS with CFW. It does all in a one single program. Features: VC NES injection into a CIA Easy made custom 3D banner Easy made custom text/footer banner Easy made screen size/aspect ratio configuration Easy made whole process! Requeriments: Microsoft .NET framework 4.5 Tutorial: You'll just follow the steps in program. But just in case: Tutorial + screenshots Step 1: Rom file selection Open the program. You'll see this screen: Press Open NES File button. It'll prompt you to pick a .nes file. For this tutorial I'll pick the game Battle City. When you pick a rom you'll be able to go to Step 2 (icon and name). Step 2: VC game icon and name This is the Step 2 main screen: All the fields are explained in the info boxes, but let me know if something doesn't understand. Complete the fields making the most legit as possible (if you want to). For example: I used a title screen screenshot in it's original size as icon (the program will automatically stretch it). When you complete all the fields you'll able to go to Step 3 (3d banner). Step 3: VC NES 3D banners This is the Step 3 main screen: Note: The program will load some default values (based on those in Step 2), but you can anyway replace these default values with ohter ones. Example: if you want the icon and 3D banner to have different images, then first complete Step 2 with the icon image that you want and then complete Step 3 with the banner image that you want. Otherwise if you are too lazy or you want the same standard as legit VC CIA, leave it as is. For this example, I'll let the same banner image as the icon one, but I'll edit the bottom banner, importing a custom one I made with GIMP (using the import and use custom footer image option): You can also make your own text banner without leaving the application, as a quick and easy solution. You can change the font type, size, and brightness. Also there's a preview of that text banner (ignore the red borders, they won't be there in the console). Doing my changes for this example: When you complete or modify all the fields you'll able to go to Step 4 (VC parameters). Step 4: VC parameters This is the Step 4 main screen: Yaaay! A lot of options! Buttons layout: Y = SELECT, X = B, L+R+Y = swap player1-player2 Y = nothing, X = VC menu If the first one is checked, the VC will be able to controll player2 (swaping controllers, holding L+R+Y). Also, the Y button will acts as SELECT button, and X button will act as B button (perfect for Mario games) If the second option is checked, there won't be any 2nd player control (holding L+R+Y will do nothing), and also, the X button will summon the VC touch menu. I didn't do that button layouts, and I (you) can't customize as I (you) want, due to it's harcoded on the VC. Disable dark filter: If this is checked, there won't be any ugly dark filter. You can preview the changes of this. Game screen size: It's just that, a screen size picker. You can preview the changes of this. For this tutorial, I want full screen, dark filter disabled, and the first button layout. Once we have everything ready, press Finish button. That's it! The application will ask you where do you want to save the CIA file and It took some seconds to create it. When the CIA is ready, the application will let you know it. Then you can install the CIA in sdcard using any CIA manager (actually I use the new FBI). (The tutorial's screenshot are from v1.0) Console screenshots: Warning: Spoilers inside! Warning: Spoilers inside! Warning: Spoilers inside! TODO, petitions, etc: For now I'll just read this thread and make changes acording to the best for all. The code will be released much later; I'm planing to do a series of VC injectors... If a new version comes, I'll post here and I'll edit the OP.
