What MiSTer TurboGrafx16 is

MiSTer TurboGrafx16 is a free core for running TurboGrafx-16 and PC Engine CD software on MiSTer hardware. Its CPU and video display controller have been rewritten for cycle accuracy. The core supports CD-ROM, Super CD-ROM, CD+G, Arcade Card, SuperGrafx mode, and backup memory saves. Other features include Street Fighter II and Populous mappers, Memory Base 128 storage, a cheat engine, and CHD support. It accepts Turbotap, two-button and six-button joysticks, a mouse, a pachinko controller, and the XE-1AP analog controller. The project is a MiSTer port of Gregory Estrade’s FPGAPCE and is part of the MiSTer project, which is open source under GPL 3.0. To install it, get a precompiled binary from the repository’s releases folder, copy the .rbf file to the SD card root, and put ROMs in the TGFX16 folder. SuperGrafx games use the SGX extension. CD images go in their own folders under TGFX16-CD as BIN/CUE or CHD files, alongside the required BIOS; do not zip them. CD+G is limited to CloneCD-format games and does not work with CHD. SDRAM is recommended for accuracy, since onboard DDR3 latency may cause issues or glitches. The project also provides a discussion forum.

Who it suits

This core suits MiSTer owners who want to run TurboGrafx-16, PC Engine CD, or SuperGrafx software, including supported CD formats and controller types. It is a fit for users prepared to install files on an SD card and, for maximum accuracy, use SDRAM.

What it does well

Supports CD-ROM, Super CD-ROM, Arcade Card, and SuperGrafx modes.
Rewritten CPU and VDC target cycle accuracy.
Includes a cheat engine and CHD support.
Supports a range of controllers, including Turbotap and XE-1AP.
Free precompiled core is available from the repository releases.

What to know first

Requires MiSTer hardware.
SDRAM is highly recommended for maximum accuracy.
CD+G requires CloneCD format and does not work with CHD.
Memory Base 128 storage benefits only a small number of games.

Limits

The core requires MiSTer hardware, and SDRAM is highly recommended because onboard DDR3 latency may cause issues or glitches. CD+G works only with CloneCD-format games, not CHD; Memory Base 128 adds storage for only a small number of games.

As github.com lists them, read 11 Oct 2026. The maker's own page has the final word.

Getting started

Open the repository website and find its releases folder.
Download a precompiled core binary.
Copy the .rbf file to the root of the SD card.
Put ROMs in the TGFX16 folder; use the SGX extension for SuperGrafx games.
For CD software, place each BIN/CUE or CHD image in its own folder under TGFX16-CD, alongside the required BIOS file.
Use SDRAM for the maker’s recommended maximum accuracy.

Verdict

Choose MiSTer TurboGrafx16 if you have MiSTer hardware and want support for TurboGrafx-16 or PC Engine CD modes, with additional SuperGrafx and controller options. Look elsewhere if you need a standalone emulator or rely on CHD for CD+G, which is unsupported.
