The development of verified custom firmware for the Sup M3 is an ongoing community effort. As of 2024 and beyond, the MiyooCFW project continues to evolve. The major milestone that many in the community were anticipating was the full public release of , which includes dedicated support for the Sup M3. The 2.0.0 beta releases have been well-received, bringing stability improvements, enhanced emulator performance, and more robust features.

Remember that the custom firmware community is built on sharing knowledge and helping each other. If you run into issues, don't hesitate to reach out through community forums, Discord channels, or GitHub discussions. The same developers who create the firmware are often active in these communities and happy to help users succeed with their installations.
Locate your MicroSD card. Look for the partition labeled ROMS , GAMES , or SHARE (usually formatted in FAT32 or exFAT).
With the firmware successfully written, it is time to load your game library and test the stability of the system.
In the world of retro gaming and flashcart modification, few phrases generate as much specific, technical intrigue as If you have stumbled upon this combination of words, you are likely deep in the trenches of reviving an older M3 (Movie Player 3) adapter, or you are a curious collector looking to bypass timebombs, fix game compatibility, or unlock the "Perfect" runtime environment for your Nintendo DS or GBA.
Follow these instructions carefully. The process is straightforward, but you must pay attention to the details.

Legal mentions
You are not allowed to distribute MAME in any form if you sell, advertise, or publicize illegal CD-ROMs or other media containing ROM images. This restriction applies even if you don't make money, directly or indirectly, from those activities. You are allowed to make ROMs and MAME available for download on the same website, but only if you warn users about the ROMs's copyright status, and make it clear that users must not download ROMs unless they are legally entitled to do so.
If you really like playing these games then you might like the authentic feeling that playing on an arcade machine can bring that can't be reproduced on your PC. Standing at the cabinet, using the microswitch joystick and buttons, looking at the arcade monitor. Nothing beats this.
You can actually build your own, using woodworking skills or you can buy from companies the various parts that you need, like the marquees that display the name of the game to the sideart that is displayed on the side. These cabinets can contain either an original Jamma harness (for attaching real arcade boards) or a computer so you can run MAME on the cabinet. But then there are retro consoles and cabinets...
Some games need audio samples. The games will run without samples but then miss certain or all sounds. Samples are kept in another directory than the roms-images. Keep that in mind because otherwise you might overwrite a rom-image with its sample.
Attention: Most roms here are outdated by now, and I have no source to update them. So a lot of the might not work with up to date MAME versions. Sorry for that.
If you use an adblocker in some cases you won't be able to download any of the files. Please consider to deactivate your adblocker and refresh this page to be able to enjoy retro arcade games.
Below you find my favorite game image files for download. But if you are looking for a complete romset you're in the wrong place. These file dumps are of version 0.260 from a full split rom set; all games should thus be self contained.

Did you know, that some versions of the emulator have a network option, enabling two or more players in the LAN or even the internet to play together? Candidats are Fightcade and Kaillera, while MAME itself seems not to support network play. Setup should be easy enough in your LAN. For WAN on the other hand, for example via a cable internet connection, at least the user of the "master" computer (the other - client - connects to) must know his or her public IP address. This article describes the problem, offers a solution and also reveals the user's public IP address. The master then just starts the emuator and enables the networking play option and tells the client(s) his or her public IP.
