Hey guys. I'm hoping for some help. I'm not nearly as technically capable as you guys on this message board. I have the sega genesis flashback. I'm just looking to add approximately 10 games at most to my system. Is there a simple step by step tutorial that can be made available for me? Thanks in advance for any help you may be able to provide.
You are OK with this? https://www.mdfbrew.org/tutorials:addgamestostock

A friend of mine is doing a write up of a basic mod which retains the menu and emulator but lets you add more games:

http://www.gniteproductions.com/projects/Flashback.html

It is a work in progress and should be done by the weekend - it meant to cover issues you can get, game compatibility and more -it looks like it about halfway done so might be best to stick with the guide posted by Steckbecken until this ones gets developed a bit more but at least now you have an alternative too.https://gbatemp.net/members/steckbecken.440044/

Thanks! Do you know if there is a limit to the amount of games on first upload?

That depends on how much free space is left your the device. Someone said, that its recommended to fill the partition at max. 2/3 of its size.

To determine the partition size, connect the Flashback to your PC and run the command "adb shell df". You will see a row like

"/mnt/internal_sd 2.8G 27.2M 2.8G 8192"

That means, the partition has a size of 2.8GB, so you could load it with appr. 2 GB of roms. But you will need days to sort the covers and extend your "all-games.ini" ;)

EDIT: Just checked the average size of a rom, lets say its 1MB, so you are able to load 2.000+ roms... good luck with adding this to your .ini file

Cool! Maybe he wants to collaborate on the wiki?

You will not be able to add so many games with the original Dashboard/Menu/Frontend what ever you wanna call it. There seems to be the same problem as the NES/SNES MINI haves, there is a Cache Folder.. Once its full the menu crashes and restarts and you wil never reach the end of youre games list. So even if you change the emulator in the main menu you will stock on this problem. This is the reason why i stopped to work with the original menu.

You can check my Older posts, i already had some tricks to add a game fullset.

Regards

my dashboard also supports long lists as well and no ini editing required :)

video playback is next (hopefully there is enough horsepower to do so)
also i am going to be migrating all of my stuff to fully support usb storage(still debating wether to keep making alternative builds that loads content from the sd card partition). its much easier when you have tons of gigabytes and a plug and play interface to just drop your stuff on.

i am mostly doing this coding for learning. I can easily use a pc and say the same, but in this case i am learning android and doing something neat with an under appreciated toy. :P.
Also notice that i am making these as separate apps from my launcher. people dont have to use them.

Do you have a clue how to use kernel modules with the installed kernel? I am stuck since days with it, i want to use either nfs or cifs to mount shares on the Flashback Device.
As far as i found out the kernel supports loading modules, so i do not have to change the whole kernel. Building the nfs/cifs modules should be enough.
But thats far beyond my android "knowledge".

There are 2 different cables: one is for OTG support and the other one is for connecting the console to a PC: I had the same problem and I would like to investigate the exact needed pinout but I have more important things right now :)

use one of these:

USBMUSBFM1.Main.jpg

and connect the usb flashback directly to it on one end and a usb stick directly to the other end. make sure it is fat32. your roms sound like they are in the right location. Click on the USB icon on my launcher and go from there. remember the current build only supports launching .bin from usb. i will do some upgrades this weekend.

can guarantee this works for me.

Very awesome progress on the Flashback! I'm very tempted to pick up one of these overpriced pieces of crap now. Might not be half bad with this breakthrough, HDMI, and if I can manage to dig up my old official six button controllers.

I can tell you that wired controllers are not supported at this time by the homebrew, wether it be mine or Hekel's there is some technical issues surrounding this.
