A Lightweight PlayStation Portable Emulator Fully Developed in C#

中文说明

这是一个完全使用 C# 开发的轻量级高性能 PlayStation Portable 模拟器。目前处于 alpha 阶段，仍存在许多兼容性、图形、音频问题。

功能说明

• HLE模拟，无需固件/BIOS
• 内部分辨率调整，支持4K原生输出
• 材质增强，支持多倍率的 xBR,Jinc,Neighbor,Lanczos
• 自适应手柄支持，无需配置即插即用
• 金手指支持，支持CWC格式金手指
• 内存编辑器，可搜索、编辑内存

当前状态

• 高效的动态重编译，游戏重编译为C#的IL运行, 对CPU及内存的占用极低。
• 模拟器能够在 i3-3215u 处理器上以稳定的 60 FPS 运行。
• 需要注意的是，目前许多游戏存在图形和音频问题 此 alpha 版本主要面向：
  • 想要探索模拟器实现的技术爱好者
  • 对 PSP 模拟器感兴趣的开发者
  • 愿意进行Alpha测试的用户

This is a lightweight and high-performance PlayStation Portable emulator developed entirely in C#. It is currently in the alpha stage and still has many compatibility, graphics, and audio issues.

Feature Overview

• HLE emulation with no firmware/BIOS required
• Adjustable internal resolution supporting native 4K output
• Texture enhancement with multi-scale xBR, Jinc, Neighbor and Lanczos filters
• Adaptive controller support with plug-and-play functionality and no configuration needed
• Cheat code support compatible with CWCheat (CWC) format
• Memory editor enabling memory search and editing capabilities

Current Status

• Efficient dynamic recompilation that translates game code to C# IL for execution, resulting in extremely low CPU and memory usage.
• The emulator runs at a stable 60 FPS on an i3-3215u processor.
• It should be noted that many games currently have graphics and audio issues. This alpha version is primarily intended for:
  • Technology enthusiasts looking to explore emulator implementation
  • Developers interested in PSP emulation
  • Users willing to participate in alpha testing
