<summary><h3>中文说明</h3></summary>
  
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
