ReSharp3DS Runtime Update

Added

Added manifest.json support in the launcher.
Added support for manifest-based .pe display names.

Example: app.pe can now appear as TestApp.
Added manifest metadata support:

name
author
version
entry
description
Added selected app metadata display in the launcher:

Author: ...
Version: ...
Added touchscreen support in the launcher.
Added better launcher file browser behavior.
Added app/folder sorting in the launcher.
Added runtime_net.cpp and runtime_net.h.
Added runtime network/file helper functions:

FileExists
DirectoryExists
EnsureDirectory
DownloadFile
Added basic crash log infrastructure.
Added basic crash screen infrastructure.
Added future log paths:

sdmc:/ReSharp3DS/logs/crash.txt
sdmc:/ReSharp3DS/logs/clr-panic.txt
sdmc:/ReSharp3DS/logs/<AppName>.log
Added centralized input snapshot logic.
Added cached runtime state for:

held buttons
pressed-once buttons
touch position
circle pad position
Added graphics target support for top/bottom screen rendering.
Added transparent sprite drawing support.

Changed

Reworked launcher app naming.
The launcher now uses manifest.json to rename the selected .pe entry instead of only renaming the app folder.
The launcher now reads the manifest entry field to know which .pe file should receive the display name.
Replaced the old update-oriented code with a smaller runtime network helper.
Improved input handling by avoiding multiple hidScanInput() calls per frame.
Improved app browser organization and metadata rendering.

Removed

Removed old updater-style API usage from the launcher.
Removed old UpdateInfo / CheckForUpdate style update flow.
Removed runtime auto-update behavior from this part of the project.

Fixed

Fixed duplicated copy_json_string_value(...) definition in gui.cpp.
Fixed generated C++ string literals where \n had been converted into real line breaks.
Fixed broken printf(...) statements in:

gui.cpp
main.cpp
runtime_net.cpp
Fixed invalid '\0' generation where real null characters were inserted into source code.
Fixed launcher metadata display being inserted into the wrong function.
Fixed author/version metadata rendering placement.
Fixed manifest behavior so metadata can target a .pe file through the entry field.

ReSharp3DS API Update

Added

Added native runtime binding for returning to the launcher:

RuntimeReturnToLauncher
Added native debug log binding:

DebugLogFile
Added native graphics target binding:

GraphicsSetTarget
Added native transparent sprite binding:

GraphicsDrawSpriteTransparent
Added support for native top/bottom screen drawing target selection.
Added native transparent sprite rendering.
Added native debug file logging path support.
Added native system info improvements:

battery level
free memory
New 3DS detection
Added improved input native behavior using cached frame input data.

Changed

Native input calls now read from a cached input snapshot instead of scanning input repeatedly.
Native graphics code can now target different screens.
Native debug logging is prepared to write logs into the ReSharp3DS logs folder.
Native runtime behavior is prepared for cleaner launcher return handling.

Fixed

Fixed pressed-once input stability by preparing frame-based input state.
Fixed broken native C++ string literals generated during integration.
Fixed crash/debug helper code generation issues.

ReSharp3DS SDK Update

Added

Added C# helper enum:

Button
Added C# screen target enum:

ScreenTarget
Added C# helper structs:

Vector2
Rect
Added C# utility class:

Timer
Added C# app base class:

GameApp
Added input helpers:

Input.IsHeld(Button button)
Input.IsPressed(Button button)
Input.CirclePad()
Added touch helper:

Touch.Position()
Added runtime helper:

Runtime.ReturnToLauncher()
Added debug helpers:

Debug.Log(...)
Debug.Warn(...)
Debug.Error(...)
Debug.LogInt(...)
Added graphics helpers:

Graphics.SetTarget(ScreenTarget.Top)
Graphics.SetTarget(ScreenTarget.Bottom)
Graphics.DrawSpriteTransparent(...)
Added save helpers:

Save.Exists(...)
Save.Delete(...)
Save.SetBool(...)
Save.GetBool(...)

Changed

Improved SDK usability for C# app developers.
Made input code cleaner by allowing button enums instead of many direct method calls.
Made touch handling cleaner by exposing a Vector2 position helper.
Made save data easier to use with boolean helpers.
Made graphics code more flexible with screen target support.

Fixed

Fixed UI.DrawProgressBar(...) so it avoids invalid/negative fill sizes.
Fixed duplicate SDK compile issue explanation:

apps must not compile two copies of ReSharp3DS.cs.

Example manifest

{
  "name": "App de test",
  "author": "Saysaa",
  "version": "0.1.0",
  "entry": "app.pe",
  "description": "Application de test pour ReSharp3DS"
}

Expected SD structure:

sdmc:/ReSharp3DS/apps/TestApp/
  manifest.json
  app.pe

Notes

This is an integration update.
Some features are implemented but still need full real hardware validation.
Crash screen and crash log functions exist, but should still be fully wired into every runtime failure path.
Some non-blocking snprintf path-length warnings may remain.

v1.2.1 · Jun 3, 2026

Fast CIA Installation

ReSharp3DS runtime update

Fixed C# static state persistence across repeated runtime execution slices.
Fixed hardware flickering caused by clearing and redrawing the console every tick.
Fixed input handling for START and SELECT.
Fixed integer printing from C#.
Fixed unstable input behavior by polling HID directly in native input calls.
Fixed several runtime/rendering issues observed on real Nintendo 3DS hardware.
Removed unnecessary rendering operations from Runtime.Yield().

On the current hardware build, Program.Main() is used as a repeated runtime tick.

This means that the C++ host repeatedly calls the nanoCLR execution engine with a limited execution slice. C# static fields are preserved between calls, so they should be used to store the program state.

Recommended structure:

namespace ReSharp3DS
{
    public class Program
    {
        static bool initialized = false;
        static int frame = 0;
        static bool oldStart = false;
        static bool oldSelect = false;

        public static void Main()
        {
            if (!initialized)
            {
                initialized = true;

                Console.Clear();
                Console.WriteLine("ReSharp3DS running");
                Console.WriteLine("Press START or SELECT.");
            }

            bool start = Input.IsStartPressed();
            bool select = Input.IsSelectPressed();

            if (start && !oldStart)
            {
                Console.WriteLine("START pressed");
            }

            if (select && !oldSelect)
            {
                Console.WriteLine("SELECT pressed");
            }

            oldStart = start;
            oldSelect = select;

            frame++;

            Runtime.Yield();
        }
    }
}
