Quick Overview

PPSSPP is an open-source PSP emulator for Windows, macOS, Linux, iOS, Android, and more. It allows users to play PlayStation Portable games on various devices with high-definition graphics and improved performance compared to the original hardware.

Pros

  • Cross-platform compatibility, supporting a wide range of devices and operating systems
  • High-quality graphics rendering, including upscaling and texture filtering
  • Active development and community support, with frequent updates and improvements
  • Extensive customization options for controls, display, and performance

Cons

  • Some games may have compatibility issues or graphical glitches
  • Requires relatively powerful hardware for optimal performance, especially on mobile devices
  • Legal concerns regarding the use of copyrighted game ROMs
  • May not perfectly replicate the original PSP experience for all games

Competitor Comparisons

PCSX2 - The Playstation 2 Emulator

Pros of PCSX2

  • More mature project with longer development history
  • Supports a wider range of PS2 games
  • Generally better performance on high-end hardware

Cons of PCSX2

  • Higher system requirements
  • More complex setup and configuration
  • Less portable across different platforms

Code Comparison

PCSX2 (C++):

void GSState::Flush(GSFlushReason reason)
{
    if(m_dev->IsDeviceLost()) return;

    GSVector4i r = m_vt.m_min.c.xyxy().runion(m_vt.m_max.c.xyxy());

    if(!r.rempty())
    {
        m_dev->Flush(r, reason);
    }
}

PPSSPP (C++):

void GPUCommon::Flush() {
    transformDraw_.Flush();
    transformDraw_.FlushUVJitter();
    textureCache_.Flush();
    depalShaderCache_.Flush();
    drawEngineCommon_.Flush();
    shaderManager_->DirtyLastShader();
    gstate_c.Dirty(DIRTY_ALL);
}

Both projects use C++ and focus on emulation, but PCSX2's code appears more focused on graphics state management, while PPSSPP's code shows a broader range of subsystem flushes. PPSSPP's codebase is generally considered more modern and maintainable, which contributes to its better portability across platforms.

Dolphin is a GameCube / Wii emulator, allowing you to play games for these two platforms on PC with improvements.

Pros of Dolphin

  • More mature project with a larger developer community
  • Supports a wider range of GameCube and Wii games
  • Advanced features like netplay and VR support

Cons of Dolphin

  • Higher system requirements for optimal performance
  • More complex configuration options may be overwhelming for some users

Code Comparison

PPSSPP (GPU initialization):

void GPU_D3D11::InitDeviceObjects() {
    D3D11_BUFFER_DESC desc{sizeof(d3d11_cb_vs_constants), D3D11_USAGE_DYNAMIC,
        D3D11_BIND_CONSTANT_BUFFER, D3D11_CPU_ACCESS_WRITE};
    ASSERT_SUCCESS(device_->CreateBuffer(&desc, nullptr, &constantBuffer_));
}

Dolphin (GPU initialization):

void Renderer::Create() {
  g_Config.Refresh();
  g_Config.VerifyValidity();
  UpdateActiveConfig();
  g_vertex_manager = std::make_unique<VertexManager>();
  g_perf_query = std::make_unique<PerfQuery>();
}

Both projects use C++ for their core emulation code, but Dolphin's codebase is generally more complex due to its broader scope and feature set. PPSSPP's code tends to be more focused on PSP-specific optimizations.

Cxbx-Reloaded logo

Xbox (Original) Emulator

Pros of Cxbx-Reloaded

  • Focuses on Xbox emulation, providing a more specialized experience for Xbox games
  • Actively developed with frequent updates and improvements
  • Supports a wide range of Xbox titles, including many popular games

Cons of Cxbx-Reloaded

  • Limited to Xbox emulation, whereas PPSSPP offers PSP emulation on multiple platforms
  • Generally requires more powerful hardware due to the complexity of Xbox emulation
  • Less mature project compared to PPSSPP, which may result in more compatibility issues

Code Comparison

PPSSPP (C++):

void PSPMixer::Mix(short *stereoout, int numSamples) {
    memset(stereoout, 0, numSamples * 2 * sizeof(short));
    for (int i = 0; i < MAX_CHANNEL; i++) {
        if (channels[i].sampleQueue.size() > 0) {
            // Mixing logic here
        }
    }
}

Cxbx-Reloaded (C++):

void CxbxrMix(PVOID pVoiceContext, PVOID pAudioBuffer, DWORD dwAudioBufferBytes) {
    // Cast the voice context to our own structure
    LPDIRECTSOUNDSTREAM8 pStream = (LPDIRECTSOUNDSTREAM8)pVoiceContext;
    // Mixing logic here
}

Both projects use C++ for their core functionality, but PPSSPP's mixing code appears more abstracted and object-oriented, while Cxbx-Reloaded's code seems to interact more directly with DirectSound APIs.

PlayStation 3 emulator and debugger

Pros of RPCS3

  • More advanced graphics capabilities, supporting higher resolutions and modern rendering techniques
  • Broader game compatibility, covering a larger library of PS3 titles
  • Active development with frequent updates and improvements

Cons of RPCS3

  • Higher system requirements due to the complexity of PS3 emulation
  • Longer setup process and potentially more configuration needed for optimal performance

Code Comparison

RPCS3 (C++):

void RSXThread::flip(u32 buffer, bool emu_flip)
{
    if (emu_flip)
    {
        sys_rsx_context_attribute(0x55555555, 0xFED, buffer, 0, 0, 0);
    }
    // ...
}

PPSSPP (C++):

void PSPDisplay::SwapBuffers() {
    if (g_Config.iRenderingMode == FB_NON_BUFFERED_MODE)
        return;
    // ...
    currentFramebufferAddress_ = displayFramebufferAddr_;
}

Both projects use C++ for their core emulation logic. RPCS3's code tends to be more complex due to the intricacies of PS3 hardware emulation, while PPSSPP's code is generally simpler, reflecting the less demanding nature of PSP emulation.
