    @g78nge If you want to just play from the SD card and keep the built-in games as they are, you need to make a folder on your SD card called GAME and then put your roms in there. Try not to use large SD cards either. All of my cards seem to be compatible but I tend to only use 16GB Sandisk cards in these Flashback units and they work great. Also, format it to FAT32 (if you are having trouble with this, use SD card formatter: https://www.sdcard.org/downloads/formatter_4/).

    @lolapaloooza If you just want to play from SD card you can follow the instruction above. If you want to replace the built-in library with your own then you need to flash the custom firmware of your choice and then create a folder on the card called rom. In this folder you then need the all-games.ini file (I have attached the stock AtGames file to this post). You can then edit this file to add/remove games. I suggest using my game manager tool to help you do this as it makes it much easier to add and remove games. My tool will also verify that your SD card is set up correctly to work with the custom firmware in the Flashback HD.

    There was a bug in the Picodrive versions that has been fixed now. Download them again from post #97 and try that. Also, if you have renamed your bin/cue files, make sure you open up the .cue file in Notepad and change the name of the .bin in there too.

    Hello everybody,
    I would just like to say a big thank you to all the people who have been involved in the process of allowing us to add games, art work and change emulator if we so wish.
    Being a Noob at all this but having followed the processes (from the shadows) on here and made a far few errors (due to me rather than others) it is possible to get this working, but the information is all spread out....not a complaint just a statement as it was all learnt across a time period and also on two separate threads.
    The issue I had with CD games was not having the BIOS in correctly (actually it was not having ALL THREE BIOS in the folder having only put the Europe one in, having misread several times the very obvious AND in the instructions) - if you read post #159 (on page 8) of Atgames sega flashback 2018 edition is out in the wild. (no idea if that will link to it or not.....see told you I am a Noob!!!) this might be why the CD games aren't playing, unless of course the download from Post #97 on here has the Bios included in them now?
    I am happy to do a step by step Noob guide if people would like, however I don't wish to take any credit or step on anyone's toes...especially as I have a question to ask in a bit. But if the above post fixed it then feel free to ignore me and I will return to the shadows.

    The updates including Genesis Plus GX need the BIOS files in the GAME folder.
    The latest Picodrive update in post 97 doesn't need the BIOS (the are included in the emulator partitonl.

    @dcuk7 A BIIIIG Thank you for the reply on this one!! what i was missing was the command in the "mount_sd.ini". Thanks to your tool i got everything up and running!!

    Last one.. any idea about the "bad" laggy sound on many of the games (e.g. World of illusion)? Any idea on how to fix this?

    There is no way to fix these sound issues, it's probably something from Atgames emulator.
    If you are using the PAL version of the games, I suggest to use the NTSC version (US or JPN) as they seem to run better.

    Genesis Plus GX and Picodrive save states are not interchangeable. If you create save states with the Default emulator they won't load in Picodrive.
    SMS works in both emulators, and GG only works with Genesis Plus GX.
    32x only works with Picodrive.
    If you already read the threads and the tips from other users you should have Sega CD working. If you are running Genesis Plus GX you will need the BIOS files.

    @lolapaloooza I'm glad my app helped. rrifonas is right that the sound issues are endemic of the system. My feeling is that the drivers they are using aren't up to scratch as some of the sound issues I have experienced in the stock Flashback units with Genesis Plus GX only happen on this system. Even using the latest nightly build of the GX core doesn't make a difference. I found that Picodrive eliminates most of the sound glitches (although Picodrive doesn't emulate Genesis sound very accurately, but that has been the same for years now).

    Just to add to the Sega CD madness, I have trouble loading certain bin/cue Sega CD files using Genesis Plus GX. Some work fine (for example Mortal Kombat) and others I just can't get to work at all (Sonic CD). All these bin/cue files are also on my Retropie and they work fine. I have two Flashback units set up here, one with GX and the other with Picodrive. For the GX one, I only use CHD files for Sega CD and they all work perfectly (well, with a little slowdown/audio glitch). My Picodrive setup works with all my bin/cue files (which is just as well as Picodrive doesn't support CHD files). I'd suggest sticking with CHD if using Genesis Plus GX and the bin/cue or img/cue for Picodrive.

    Hi BillyHGamer

    From my understanding Picodrive doesn't support GG so you won't be able to play them if you have used that update.
    There are two emulator options and unfortunately neither play all games, so it is a case of picking which one plays the most of the games you want.

    Genesis Gx Plus (the original emulator) plays everything except 32X games/roms

    Picodrive plays everything except Game Gear games/roms

    Depending on what your CD games/roms are saved as, may also depend on which update/emulator you wish to use.

    The CD games/roms are normally .bin/.cue or .img/.cue or .chd and again each of these need little adjustments for them. I had a fair few issues getting it all working myself and struggled with websites for downloads so happy to help you out.

    What are your CD games/roms saved as?

    Picodrive doesn't work with game gear. It was told before.

    We don't share links to download stuff. You can search in archive.org or a torrent site.

    If you can make Genesis Plus GX runs in your PC using Retroarch, you can use the same BIOS files and copy to the game folder in the SD Card. Use this information to learn about the BIOS files needed:

    Hi rrifonas,
    This most likely is a stupid question, but here goes.
    The Genesis Plus Gx when run on Wii has the option of Lock on cartridges (Sonic & Knuckles/Game genie etc). I have tried to figure out if it is possible to do the same thing on this system and whilst I understand the need for the correct BIOS file in the correct folder on the SD card, there unlike on the Wii isn't an option menu to turn on the lock-on cartridge.
    Is it possible to do that on this system or has that part been removed? I have looked in this emulator and the Wii file to try to see if possible but I am completely out of my league on all this stuff, and wondered if you would mind helping
    In regards to my previous post I had no intention of putting a link on, and was going to suggest archive.org as that is where I found the stuff, so hope I haven't done anything improper.
    Thanks

    Hi @MB79, the question is valid.
    I haven't tried game genie or the lock-on feature yet, but I can tell you the core is intact (it is the same running in SNESC, and almost the same as the Raspberry Pi), and the feature is also available in RetroArch so in theory it works. I'm not sure if and how the emulator handles this, and if we need to set any core setting in retroplayer.ini. I will see how it works and get back to you.

    I only have one and it's a .bin file but I also tried .rar and both no luck on the picodrive and mine plays the .bin .Sms also the game gear games just fine on the picodrive just not sega cd and 32x so I guess I will try Genesis gx plus with the bios files
