TeknoParrot

TeknoParrot emulates Sega NAOMI, Sega NAOMI 2, Sega NAOMI GD-ROM and 8 more systems. It reads 20 files, 15 of them required: without a required file it does not start games. A required file is needed only by the machines that use it. Each file below cites the line of source code that reads it.

Install this emulator's files

With RetroBat: the installer finds RetroBat and its BIOS folder, then downloads only the files TeknoParrot reads there and checks each one.

Open the Start menu. Type PowerShell and open it. Paste the line. Press Enter.

Technical notes

Launcher and emulator suite for arcade boards. TeknoParrotUI is open source and read here at its pinned commit. It runs a game through one of the components its updater installs from the releases of teknogods/TeknoParrot, every one of them closed source: the TeknoParrot and ElfLdr2 loaders for PC-based and Lindbergh boards, forks of Dolphin (Triforce), Play! and PCSX2x6 (Namco System 246/256), RPCS3 (Namco System 357/369) and Cxbx-Reloaded (Chihiro), and a family of board emulators named Tekno* (TeknoNaomi, TeknoMVS, TeknoCPS, TeknoModel2 and others). ref: TeknoParrotUi/MainWindow.xaml.cs:509-669, TeknoParrotUi.Common/EmulatorType.cs:9-67

RetroBat starts TeknoParrotUi.exe and picks the component by the core name: triforce, pcsx2x6, play, namco2x6, namco3xx, chihiro, or none for the loaders. For Triforce, System 2x6 and Chihiro the game image itself is written as the profile's game path. ref: emulatorlauncher emulatorLauncher/Generators/TeknoParrot.generator.cs:177-201, emulatorlauncher emulatorLauncher/Generators/TeknoParrot.generator.cs:266-270

The components read here are the release assets of 2026-10: TeknoNaomi 0.1.0.5, pcsx2x6 1.0.0.11, RPCS3 1.0.0.7, cxbxr 1.0.0.20, CrediarDolphin 1.0.0.10, Play 1.0.0.34 and TeknoParrotElfLdr2Core 1.0.0.1472. TeknoNaomi, TeknoMVS, TeknoModel2 and TeknoS11 are protected with VMProtect (release-manifest.json "protected": true) and expose no ROM name, size or hash to a static read. The TeknoParrot and ElfLdr2 loaders name no firmware either.

TeknoNaomi takes --set, --rom-root (the folder of the selected game ZIP) and --chd-root. Its catalog, exported into TeknoParrotUI, gives each of the 349 sets the ordered list of romsets it opens under the ROM root: the set, its parent, then a BIOS set. Nine BIOS sets close those lists. Their members and hashes live only inside the protected binary. ref: TeknoParrotUi.Common/TeknoNaomiCatalog.cs:17-372, TeknoParrotUi.Common/TeknoNaomiLaunch.cs:56-77, TeknoParrotUi.Common/TeknoNaomiLaunch.cs:90-98

The pcsx2x6 component is ReaverTeknoGods/pcsx2x6 at c6e731ac0b9859011d358c021b7e2c9c95296a93 (the build reports v0.0.22-24-gc6e731ac0), a fork of PS2Homebrew-arcade/pcsx2x6 whose merge base with it is 956d4c66b0ac2eaefe7591a763f7b3cc80d1eae1. The release ships portable.txt, and an empty portable.txt puts the data root in a TeknoParrot folder beside the executable, so the BIOS folder is pcsx2x6/TeknoParrot/bios. ref: pcsx2x6 pcsx2/Pcsx2Config.cpp:2196-2202, pcsx2x6 pcsx2/Pcsx2Config.cpp:2311

Play! runs System 246/256 games from its arcadedefs (dongle, CD or HDD image) with HLE and loads no BIOS. CrediarDolphin ships Sys/Triforce/segaboot.gcm, which it opens for the test menus, and the free DSP ROMs in Sys/GC. The RPCS3 fork refuses to boot without installed PS3 firmware ("PS3 firmware is not installed or the installed firmware is invalid."). The cxbxr fork keeps the Chihiro media board files of Cxbx-Reloaded under EmuMediaBoard.

Not documented: the BIOS sets of TeknoMVS, TeknoCPS, TeknoSS32 and the other Tekno* board emulators. TeknoParrotUI names only the game ZIP for them (ExecutableName in GameProfiles) and the binaries are protected.
