    I noticed some games that have FM sound don't play it in FM. A few examples are the translated version of Phantasy Star, Megami Rescue, Galactic Protector, and Super Racing. I'm sure there's more.

    EDIT: Fixed a misspelled word.

    If you use the game manager app, just do the following:
    1. put your SD card in and choose the Open all-games.ini button
    2. select the option to set up a new SD card
    3. choose your region from the menu and click start
    4. when it asks you if you want to download the custom firmware just say yes
    5. put the sd card in the flashback, let it do the update
    6. after the update completes, take the card and put it back in the computer
    7. the app will see that there is an update file on the card and ask you to remove it, say yes to this
    8. now select the Open all-games.ini again and choose your sd card, you can now start to add games to it
    Hope that helps.

    Yes you should be formatted as FAT32. The game manager set up will tell you if the card is in the correct format.

    If you use the app it will enable the AtGames standard SD card support (providing you say yes to downloading the custom firmware) but it will also let you add the games so they show up in the main menu, which is nicer imo.

    There are no real limitations. I'd say don't have more than 500 games (I try to stick to 300 or less). Use unzipped ROMs for best compatibility.

    Yes the custom firmware is based on the latest AtGames firmware. You can flash between custom and official with no issues (you will always be able to use AtGames firmware in the future even if you are running custom). I don't think there will be any new official firmware released for this unit now but if it does I am sure we will keep the custom firmware updated.

    great, thx for fast explaind, looking at customs seen there 2 firmwares for Sega Mega Drive Flashback HD

    Mega Drive Flashback HD 2018 - custom firmware based on the US FB3680_v.2.01
    Mega Drive Flashback HD 2018 - custom firmware based on the US FB3680_v.2.01 (Picodrive)

    which one is in Game Menager App, and which one is better? custom firmwares can be flashed by another custom? and at actually Game Menager App and custom firmware allow to add and play other Sega roms like GameGear, CD, X32?

    The game manager downloads the version with Genesis Plus GX. This is the emulation core that AtGames shipped the unit with. The supported systems with each core are:

    Genesis Plus GX - Genesis, Master System, Game Gear and Sega CD
    PicoDrive - Genesis, Master System, Sega CD and 32X

    I made the decision to only offer the Genesis Plus GX through the game manager so that it runs as close to stock as possible. Flashing the PicoDrive firmware will mean no Game Gear support. I think most people would prefer GG over 32X support.

    You can't easily add bezels. The only way is to replace the ones on the device but that requires unpacking the firmware, replacing files, re-packing and flashing back to the unit (not the easiest process tbh).

    The Overdrive option is a funny one. I find that if you disable Background Music and enable Overdrive, the unit performs a little bit better but I've tried with just Overdrive on and off and I can't really notice any difference.

    Thanks for the detailed reply dcuk7, I must have been having a mad half hour as I didn't have the sd function at all. I must have watched it in a video and then made myself beleive it was on mine! I flashed the console with the official firmware so now have sd function. Has anyone noticed colour changes in games. Playing shinobi or desert strike there are colour changes where the games go grainy then back to normal then back to grainy on dessert strike and shinobi,. Do I have faulty one?


    Is there a tutorial video of how to install the custom firmware instead?

    Better get a mega Pi case with a raspberry pi 3+, install the blast 16 frontend and forget this defective console forever!

    Hello,

    I applied the GX Plus custom firmware and noticed that the 6 button controls dont' work for all games that support it, but if I switch and try the PICO firmware then the 6 button controls work. Is there a way to add 6 button support to the GX Plus firmware?

    See @spanner post here for a trick for 2 disc SEGA CD games.

    If you use the Game Manager app you can download the latest firmware for your region without doing the AtGames registration. This is a better way to do it IMO because @rrifonas has done a marvellous job at making both Genesis and Mega Drive versions (AtGames only offers Genesis branded firmware, which means your Flashback will change to Genesis instead of Mega Drive. This is only cosmetic though, it operates just the same.) You you will also have the option to use your own games with box art if you choose to do so in the future.

    Hi,

    I purchased the UK version of the 2018 Sega Mega Drive Flashback from Argos a few weeks ago (it only cost £30!).

    I'm now interested in trying out the custom firmware that you guys have written for it. However, I'd prefer to backup the stock firmware in my machine first. I realise this will require me to solder in a USB port (which I'm comfortable doing). But I'm struggling to find a simple guide on how to use RockChip's utility for uploading and downloading new firmware to the NAND flash chip. Can anyone here point me in the right direction?

    Thanks in advance.

    You only need to do a simple bridge on the board to enable direct USB access, I think there is a image with the solder points in some thread. Connecting the device to a computer while pressing the recovery button will put the device in LOADER mode. I soldered 2 jumpers to the "Menu" button to make it easier to put the device in LOADER mode without need to reopen it.

    Once in loader mode, you can use "rkDumper" to backup the device, using the following command-line:
    rkdumper.exe /last dump

    This tool will dump all partitions and the parameter file. It will also create a .cfg file (config_16.cfg) that can be used with AndroidTool to upload the firmware back to the device.
