PUBLIC RESEARCH WIKI · SOURCE-VERIFIED · REVIEWED 17 AUG 2026
PSP recompilation, documented carefully.
A public, evidence-driven map of PSP static recompilation, portable runtime architecture, hardware behavior, and the Nakagawa Recomp project.
Choose a path
Use the wiki as an orientation layer; implementation claims remain subordinate to the current public source.
🧭 Start here
Understand the evidence labels, reading order, and public/private boundary.
📚 Knowledge base
Browse topic-organized PSP reference articles and the hardware findings registry.
⚙️ Architecture
Follow the executable-to-generated-code pipeline and its portable runtime seams.
🔬 Evidence
Learn what source, tests, emulators, private routes, and physical PSP measurements can prove.
CURRENT PROJECT SNAPSHOT
Deep title validation, broader long-term architecture
Nakagawa Recomp is validated most deeply against the USA PSP release of Hot Shots Tennis: Get a Grip (UCUS-98701). The public source head reviewed for this wiki is 4eda0c4f. General PSP compatibility is not claimed.
Working
Boot, title, menus, and qualified private match routes for the current validation target.
Partial
Graphics, audio, timing, HLE coverage, save/load evidence, and public tooling remain acceptance-sensitive.
Not accepted
Fresh-machine public-source, user-supplied-game end-to-end release acceptance has not yet been achieved.
Host and display status
Windows 11 x64
Current first-class development and validation host.
Linux
Future native target. Not currently supported end to end.
macOS
Future native target. Not currently supported end to end.
The PSP guest framebuffer is 480×272. The current resizable SDL host window begins at 960×544; a true user-selectable native 480×272 / 1× presentation mode is not currently implemented.
Research discovery
- Hardware Findings Registry
Measured PSP behavior with evidence labels. - Hardware Replication
Safe, comparable hardware-oracle workflows.
- Replication Wanted
Current high-value measurements. - Planned Experiments
Open, discriminating, public-safe tests.
- Contradictions Registry
Claims that need resolution or correction. - Learning Path
Build a static recompiler from guest contracts upward.
Public-safe by default
The public project ships source and research documentation, not proprietary PSP game content. Users must provide their own lawful supported game input locally. Private title runs can validate an integration route; they do not publish game data, prove PSP hardware semantics, or establish release readiness.
