RSDKv4.NET

A port of RSDKv4 to C# and XNA for Windows Phone 7 and desktop. Based on the original decompilation, with hardware rendering based on Sonic CD.

What works

• RSDK file reading (both v4 and v4u)
• 2D Rendering (sprites, blending, etc.)
• 3D Rendering
• Animation
• Collision
• Scripting/Objects (mostly)
• Keyboard input
• Touch Input
• Save Data
• Music & Sound effects
• 40% of Native Menus
• Builds and runs flawlessly using NativeAOT on .NET 7

What doesn't

• Controller Input
• 60% of Native Menus
• On the fly palette changing is incredibly slow on some hardware
  • There are two palette implementations, FAST_PALETTE uses a shader, default does not.
  • FAST_PALETTE is unsupported on the XNA Reach profile (Windows Phone 7)
  • Another solution will be required
• Some background modes that aren't used by Sonic 1 & 2

What's not planned

• Mod support
• Text script interpreting
• Software rendering (too slow in C#)
