custom firmware for sega flashback 2018

[Flypop]

I was poking around with this console and discovered that the Genesis Plus GX CFW also runs games from the SEGA SG-1000 (no need to change extension .sg is just recognized) and SEGA PICO (with extension .md just like a megadrive game). In the case of the Picodrive CFW I just don't know because I'll stick with the Plus GX. Nice to see some surprises like the Wonder Boy / Adventure Island esque like gameplay and that shocking Pokémon collaboration with SEGA.

Compatibility is definitively not 100%, certain games such as virtua racing uses special chips in order to run 3D graphics and to do special mathematical calculations. Such games are unsupported or runs with glitches. In the case of Super Street Fighter 2 I don't know but another cause could be a corrupted ROM, in that case I recommend you to search first for a verified ROM from a No-Intro Romset for example.

hakchi supports the mini, not the atgames consoles.

I have the 2018 model, but I'm having issues using original Sega 3-button controllers with it. I've done some testing with the Multitap ROM that shows/reads button inputs. I can't recall the specifics at the moment, but from what I remember, A is read as Start+A, C does nothing, B is read as A, and Start does nothing.

This only applies for Player 1; the 3-button controller works perfectly as Player 2.

AtGames support weren't great when I tried contacting them earlier.

Has anyone else been able to get a 3-button controller working as Player 1, either with the original firmware, or with rrifonas' CFW?

If not, is there any way to modify the CFW to allow correct inputs from the 3-button controller?

Check that your SD card is inserted or go to atgames firmware site page and download the sega genesis flashback firmware and reset.

My console hasn't got a SD card mode

If your Flashback doesn't have an SD card slot, then your model is the 2017 version. This thread is for a different model.

@rrifonas
Very much thx for your effort with the cfw. Bought my New fb 2019 here in germany yesterday for only 30€ (seller got 8 left in Stock) and was shocked that it couldnt load or save anything to the SD. After reformating my 32gb SanDisk card with sdformatter the console finally accepted it and installed the Update. Used your cfw after that which Sets the fb to a higher Level.

@DoctorEvil8
Thx for the Infos about the segacd bios.
Now it's working

Did somebody have a dump of the Rom folder (with description and Covers) from the original partition?
I want to extend the Roms on the SD instead replacing the whole content. Would be really nice.

And is there any fix out for the gamemanager to get the correct Covers from Google?

Additional question... I maybe want to change the Controller for the retrobit one. But then i will loose the rewind function, or is there a Button combination for it?

I haven't touched my Genesis FB in a while, but if I recall correctly you can use a mount_sd.ini file in the SD Card to dump your own rom folder:

To mount the rom partition in the SD Card:
-> Create a file mount_sd.ini in the root of the SD Card
-> Copy a backup from your 'rom' partition a 'rom' folder in the root of the SD Card. If you don't have a backup or the rom folder, it will be copied on the first boot after the mount_sd.ini file is copied to the SD Card
-> Removing the SD Card and rebooting the device will revert to the original partition
-> Renaming/deleting mount_sd.ini will also revert to the original partition

making a mount_sd.ini doesn't dump the original rom folder from the console to the sdcard. it just makes fb use the folder on the sd card. i got this already working via gamemanager. but i also want all the existing games from the fb drive on my sd to make a complete collection. otherwise i had to get all the games manually, create boxarts and write the infos for them. would be much easier if i could get the folder, which is already included at the fb internal drive.

ok. found something (thats all backup partitions from the stock FB 2017):
IF, IN ANY CASE, YOU MANAGED TO DAMAGE YOUR CONSOLE TRY TO USE THIS STOCK FIRMWARE TO TRY TO RECOVER IT (flash ALL partitions with ROM_Dumper_Tool.exe renaming parameter.txt to parameter. ): https://mega.nz/#!bg9wVR5J!thSs92YW1jNGH5ayh_EIDxUC_yNkCFyhuEgyHhcrs-Q
IN THIS CASE YOU DO NOT NEED loader PARTITION.

Did you ever replace the console you had that froze after 10 minutes of running time?

It's been a while, but yes, there is a way to perform a rewind on the Retro-bit wired controllers. I believe it is START and Left+Down together. It's definitely START and a diagonal on the D-pad if Start Left+Down doesn't work.

Yes it does work because if you try to use the level select on the original Golden Axe it conflicts and causes the rewind function rather than the level select to occur!

Here is the custom firmware for the EU version (Mega Drive Flashback HD 2019 / Mega Drive Flashback HD 2018):

Update for Mega Drive Flashback HD (EU) with Sega CD support (Genesis Plus GX)
Update for Mega Drive Flashback HD (EU) with 32x support (Picodrive)​

If you are looking for the files to the US version (Genesis Flashback HD 2018), look at this post or download these files:
Update for Genesis Flashback HD (US) with Sega CD support (Genesis Plus GX)
Update for Genesis Flashback HD (US) with 32x support (Picodrive)

I will update my other post adding these links. Thanks @dcuk7 for kindly provide the dump from his Mega Drive Flashback. I've tested with my Genesis Flashback 2018 and it was properly converted to a "Mega Drive Flashback" so it should work in all versions (UK, Germany, Australia).

Just as a recap, this custom firmware unlocks with file extensions in the GAME folder, so it will read all files in this folder. This mod enable Genesis Plus GX to load Master System, Game Gear and Sega CD games from the SD Card.
The "Picodrive" update has the same mod but replaces Genesis Plus GX with Picodrive. This update add support to 32x and fixed the speed and sound issues with PAL games (I've tested with "Sonic 2" for Master System), but it breaks Game Gear (Picodrive doesn't support GG) and Sega CD (I couldn't find if there is a specific folder to drop the BIOS files).

Regarding the 'technical aspects', Genesis Flashback HD and Mega Drive Flashback HD are exactly the same device, using the same emulator and they have the same 'rootfs' partition. The only changes between Genesis and Mega Drive is the box art in the "roms" partition and a few images in the emulator partition.

Has anyone ever had issues with the audio when playing SegaCD/MegaCD games using the sega_update_megacd_unlocked.zip firmware at all please? I only recently purchased a Sega Megadrive Flashback again, this will be my fourth as people kept wanting one so ended up getting the one I had running at home Well this time I decided to use the sega_update_megacd_unlocked.zip to play SegaCD games, however the sound was very distorted and crackly for some reason.

Interestingly I found if I installed the sega_update_20190226_EU.zip that still has the 'about' tab with Megadrive logo the Sonic_CD_(USA).CHD file (for example) was still visible on the SD card option and will play fine with much better quality audio with the BIOS_CD_E.BIN, BIOS_CD_J.BIN and BIOS_CD_U.BIN files in the Game folder.

Could there have been some I missed with the sega_update_megacd_unlocked.zip firmware at all?

Hi,

I am having an issue updating the firmware on my console. I have downloaded and followed the instructions.
However the console just keeps restarting and updating over and over again?

Thanks in advance

When it updates, every time you reboot, it will ask to update. again Say no. It's likely because the update file is still on the SD card. Once the update is done, take the SD card back to your PC and delete the update file.
