Hi,Asdolo. Could you add the function to edit the rom header ?Sometimes I find the parameter wrong in header when I use your tool. Especially Mapper and Wram.To edit them by manual is very necessary I think.

Do you have some examples handy of wrong header detections? Note that NES VC uses Nintendo's TNES header.

For WRAM, it seems the values in iNES headers can't always be trusted, check bootgod's NES Cart Database for sure.

Also, regarding your earlier issue:

Hello, Asdolo! I test your NSUI Beta 26 and Beta 27. It's a great tool. I have two 3ds so I like play Download Play nes games with my family. In Beta 26, it has no clipup and clipdown function and many games has image problems. Nes games made by Beta 27 is better than Beta 26, some image problems be solved in Beta 27. But I find a new problem in Beat 27. When I quit Download Play nes games to home page in my guest 3DS, an error always happen and it auto reboot. My host 3ds is OK. It didn’t happen in any games made by Beta 26. Could you fix it? Thanks!

Hm, I tested with two 11.6U systems and didn't have this issue. Just in case I also tried them in 11.6J (emuNAND), those also seemed to exit okay.

Does this happen in any non-VC Download Play games, like Mario Kart 7?
Since having this issue, have you tried Download Play CIAs created with Beta 26, do those still work as expected?
Does it matter which 3DS is host/guest, or does it happen with either configuration?
What are the systems' firmware?

I 'm out without my 3ds many days. I will try to switch my host 3ds and guest 3ds when I back. Thanks.

I test it , it's the matter which one is host and which one is guest.And I play non-vc games like Mario Tennis,it's ok.

Many examples. Just like Wai Wai World. If you make it by tool, it can't run. We should change some parameters in header. I will share my ideas in a few days. So I think it's necessary to allow us fix header by manual.

I have switched my host 3ds and guest 3ds. Now I'm sure that it's about which 3DS is host/guest. When a guest 3ds exit, it will reboot.

Hi, Asdolo.
I find a much more better nes Virtual Console. I dumped and decrypted Ganbare Goemon 2(J) from JPN eshop and I think it's the latest Virtual Console.
Compare with games made by Beta 26 and Beta 27, it has less image error. You know some games has little image flaws.And many of them would be fixed in this Virtual Console.
Besides, it has a fuction "PPULineCycles" that your NSUI model console don't have. I'm try to set the value higher like 500, some games like Contra Force become perfect! In the past, it has a serious flicker in Contra Force. And now it's OK.
I think it can fix many games. So could you replace your model console with it ?If you need, I will send you the Ganbare Goemon 2(J) cia I dumped.
Thanks.

their are some games that the software just does not support, i think it is partially due to nintendos emulation software, and maybe due to save types and whatnot, i had a similar problem with mario rpg legend of the 7 star on the snes converter, im sure as time goes on, more capabilities will be patched in, thats just the way it is with modding

for mario rpg, I used the retroarch VC thing. Is there a similar retroarch VC but for nes ?

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:

Step 1:

Open the program. You'll see this screen:
mH7hLnL.png


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:
This is the Step 2 main screen:
4jRMcUE.png


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:
KZDxJ05.png


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:
This is the Step 3 main screen:
T1lL2M2.png


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:

ygxdczG.png


When you complete or modify all the fields you'll able to go to Step 4 (VC parameters).

Step 4:
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:

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.

Download links:
v1.2: MEGA
v1.1: MEGA
v1.0: MEGA

Changelog:
v1.2:
* Fixed: Now the injections should be region-free (not tested).
* Fixed: Now the parental control won't be a trouble.
+ Added: Now you can choose 3 different types of 3D Banner, NES, Famicom and Famicom Disk System! (thanks to @cots)

Screenshot of Ice Climber inject with Famicom Disk System 3D banner:

v1.1:

+ Added: more roms compatibility (still not even 99%)
+ Added: Game recognition. Most of official roms (non hacks/translated/HVC roms) now will be recognized and it'll auto-complete game name and publisher.
* More Stability™ (?)

v1.0: Initial release


Enjoy!

Is your ROM not working? Try this instead.
will they're be download play support ever?
