TempAR

TempAR is a cheat engine plugin for the PlayStation Portable (PSP), supporting both CWCheat and PSP Action Replay (PSPAR) code types in a single plugin. It runs on custom firmware (CFW) as a kernel-mode .prx plugin loaded via seplugins, and includes an in-game menu, a live memory search / cheat finder, a MIPS disassembler, and a memory browser/editor — everything needed to both use and create PSP cheat codes on real hardware.

It is a heavily modified descendant of MKUltra, which is itself a modified descendant of NitePR — carrying forward PSP cheat-device history back to the CWCheat/PSPAR era while adding features neither predecessor had (favorites, extended PSPAR code types, PSX GameShark support for POPS titles, multi-language UI, and more — see the changelog).

Features

• Dual cheat engine: CWCheat and PSP Action Replay (PSPAR + PSPAR Extended) code types, both loadable from the same cheat database.
• PSX GameShark support for PS1-on-PSP (POPS) titles.
• In-game cheat menu: toggle, edit, rename, copy, favorite, and reorder cheats without leaving your game.
• Memory search ("cheat finder"): 8/16/32-bit exact and unknown-value search, with results addable directly as new cheats.
• MIPS disassembler & memory browser/decoder: inspect and patch live game memory on-device.
• NitePR / PSPAR.com .bin compatibility: load existing NitePR .txt and PSPAR .bin cheat files without conversion.
• Homebrew & PS1 (POPS) support, with a lightweight tempar_lite.prx build for memory- constrained modes.
• Skinnable UI and multi-language support.

See the full user guide for hotkeys, cheat file formats, and a detailed comparison against PSPAR, CWCheat, and NitePR/MKUltra.

Installation

Copy the seplugins folder from a release build to your PSP's Memory Stick, then enable the plugin for your desired mode (game.txt/pops.txt) — see the plugin readme for full installation steps and hotkey reference.

Building from source

TempAR builds against the PSPSDK MIPS toolchain via Docker — no local PSP toolchain install required. From the repo root:

docker run -it -v "${PWD}:/src" -w "/src" pspdev/pspsdk make release

This produces both tempar.prx (full) and tempar_lite.prx (lite) builds, packaged as a .zip in a build folder. Build process tested on Windows 10.

For build internals, PSPSDK/toolchain compatibility notes, and codebase architecture, see the developer documentation.
