About This File

New Version (v0.12 Beta) 4th Oct 2021 - See Changelog For Updates - AIO Version Includes All files from @mpham & @Meliodas2255 Massive Thanks to @shadow256 for Updates


I've added an option to skip image conversion you WILL need to provide the Icon file as a 256 x 256 Pixel JPG and if you use it the Logo file it must be a 160 x 40 Pixel PNG
NOTE!! You MUST tick the Disable Image Conversion option BEFORE choosing your image files

GUI for the NSP Forwarder Tool for 12+ that @mpham posted. I'm not the best at programming so this is done with AutoIT I've attached a Compiled exe version and the Script to compile it yourself

Important you WILL need the prod.keys file generated by Lockpick_RCM

15th Sept 2021
 - Big thank you to @shadow256 for continuing to update this in my absence, I've got some ongoing health issues which have meant I'm not able to get on the PC as much as I'd like, I've just put together an updated v0.10b AIO version from the script (AU3) posted by @shadow256 I've only had time to do a quick test but it seems to be working well.


  • Build NSP Forwarders for NRO and RetroArch Rom's
  • Accepts PNG, JPG/JPEG, BMP, GIF and TIF Images for the Icon and Logo
  • Automatically Resizes and Converts Icon and Logo to the correct dimensions (The Icon should be at least roughly square and the Logo should be wider than tall to look acceptable) but any will work
  • Allows prod.keys to be located anywhere
  • Generates a Random TitleID or can be entered manually

  • Fix some other bugs

0.11 Beta Updates by @shadow256

  • Default logo file and his backup will not be deleted anymore at the end of the process, should prevent for some big problems

0.12 Beta

  • Tidied up Menu Title
  • Added option to disable icon conversion, Tick the checkbox BEFORE selecting your images (I need to rework the menu to make this option easier)
  • Cleanup of files also added to the close (X) button

Known Issues

  • Some forwarders are created with ? logo when installed on the switch, 0.12 Beta adds an option to disable the image conversion completely as a workaround as no rootcause has been identified

There's probably 100's of ways to break it so backup any files first

Added a couple of Logo.png files I created

LibRetroLogo.png and HBMenu.png, use them with the Logo Path option, they show up top left when you start the forwarder
