nothing specific, I got everything else running but FBA. I would be fine with cps1/2. I have found the bios files but didn't know where to place them or what format they needed to be. I was starting to question if v0.2.97.43 was the correct romset.

This romset should work. The best way to test is to install RetroArch on your PC and load the .7z files with FBNeo core. If the game loads with FBNeo, it should work on the Flashback.

thank you guys. I have update with your firmware and i have play with wonder boy deluxe. I live it! unfortunately I have downloaded other roms but only very few work. Some don't even leave. Others seem to start with a black screen and then return to the main screen. Are there any recommendations on roms to look for? It is possible to run the roms .md work?

Nice, so the firmware/core is working. The best way to test is to install RetroArch and the same core (MAME 2000) in your PC and test the roms. If the roms work in RetroArch, they will likely work on the Legends Flashback.

.md files (Genesis games) = rename them to .bin and remove the spaces on the file names

Mortal Kombat 4.0 works. T-Unit Midway boards do not. I have a PSClassic running retroarch and loaded up some games with FBNeo and they worked. I tried them on the legends and they don't. I tried putting bios in the 'game' folder with the roms, same as sega-cd. do they go in the 'fba' folder?

I have the neogeo.zip and some other bios. Anyways Im trying to get MSH, XCOTA, AVP, something CPS2 to work. But I keep failing. I finally got Sega-CD with sound working on my own, but im stuck trying to put something better than SF2 on this Legends Flashback.

you can rename the extension .md to .smd also. Quick question, can the colecovision and tg-16 etc fba roms work on the Legends Flashback?
I never tried. This is the regular core, so it should work if the files are named correctly.

Midway T-Unit games don't work, there is something wrong with the emulator. As commented by Draxxon, Mortal Kombat version 4.0 works because it's based on a Y-Unit board.

X-Men vs Street Fighter, Super Street Fighter II and Marvel vs Capcom work. I will try to unbox my Legends Flashback tomorrow and test some of these games again. Don't expect anything much better than SF2 running on this console.

## Emulating consoles
You can emulate consoles (with specific romsets, dats are also in the [dats](dats/) directory) by prefixing the name of the roms with `XXX_` and removing the `zip|7z` extension, or using the `--subsystem XXX` argument in the command line, here is the list of available prefix :
* CBS ColecoVision : `cv`
* MSX 1 : `msx`
* Nec PC-Engine : `pce`
* Nec SuperGrafX : `sgx`
* Nec TurboGrafx-16 : `tg`
* Sega GameGear : `gg`
* Sega Master System : `sms`
* Sega Megadrive : `md`
* Sega SG-1000 : `sg1k`

So do I unzip the turbo grafx FBA bonk file, re zip as a .7z file, rename the file "tg_bonk.7z, then use advanced renamer to remove the .7z extension, then place the file in the "GAME" folder?
That's what I tried but I didnt have any luck. Is it possible to get bonk and other TG16 games running?

I finally did get FBAlpha working. I was Extracting to a folder and re-compressing the folder. Once I compressed the individual program files into a 7z without the folder they worked.

I was reading about the support for consoles in FBA and it needs the --subsystem, so it won't work on this console.

I finally got everything working and have done some actually playing. It seems like later Capcom games (like SFA3) tend to crash often. I'm guessing its the rewind feature that is doing it. also, after the crash, no roms will load until I do a hard reset.

It's not rewind feature, but the total memory and the tempfs partition.
The device has only 128MB RAM and a 128MB NAND, with a very small tempfs partition to extract the games.
Any game larger than Samurai Showdown 4 will crash while extracting the game. And the files won't be deleted until you restart the device. That's the beauty of the read-only partitions, the device will never brick due to this kind of issues like free disk space.

Thanks for the info. I've learned a lot tinkering with this little system. Speaking of the rewind feature, that's where this little system really shines, in my opinion. Thanks again for all the help!

Awesome job, rrifonas! Maybe the expertise you gained doing this can help me: I have been trying to make some mods for my Atari Flashback 9 by changing some files inside the ext4 data and emulator squashfs partitions (similar to what you did here) and all goes well until I try to repack the image becuase the tools I tried to use (imgrepackerrk, afptool, rkImageMaker) always fail complaining of a missing "package-file". Do you mind explaining what tool / steps you use to recreate the final arcade_update.img file that is used for the upgrade? Many thanks!

Cool! It's good to have someone modding the Atari Flashback.

package-file is a simple file to map the partitions to the .img files, this sample is for the Genesis Flashback HD 2018:

Code:
# NAME Relative path
parameter    parameter
emulator    emulator_scd.img
data        data_no_test_sd_on.img
backup        RESERVED
#update-script  update-script
#recover-script recover-script

The tool to compile to final image is imgrepackerrk with the parameter /rkaf. Let me know if you need additional information.

Thank you!!! I ended up finding my answer via trial and error about and hour ago but it is good that you confirmed it before I tried to update my device. I manually created the package-file which for the Atari FB9 is

Code:
# NAME            Relative path
#
#HWDEF            HWDEF
parameter        parameter.parm
rom                rom_3050.img
emulator        emulator.img
data            data_no_test.img
backup            RESERVED
and indeed used the /rkfa parameter with imgrepackerrk because I empirically verified the arcade_update.img created by you was of that type. I noticed the img file provided by the vendor has the "RKFW" header as well wrapping the file as FIRMWARE type, but since your mod worked for the arcade using RKFA, I will go with that and try to update my Atari FB9. Thanks, again! If/when I have a mod useful to share with the community, I will do so.

How would I create a package-file for the Legends Flashback? I've ran into the same error. I'm just learning. Trying to add sonic chaos to the main menu. I'm hoping to learn how to swap roms as I'd like to make this a dedicated Sega Master System.

Also these are $11.00 at some Wal-Marts right now. I hear the new version coming out has no SD card slot.
