Sega Megadrive (Genesis) Flashback Mini HD with an USB on internal mother board

WD_Gaster · Jan 11, 2018

on my end i can claim success with a usb stick up to 128gb's

however they dont consume as much energy as a usb hard drive, but worth a shot i guess. you may need to externally power it with an external 5 volt source.

Im in hand of some good ones which worked well on my gpd xd and gpd win im pretty sure they will work. With that i will completly move the rom directory to external storage. And from that point we can focus on different frontends and load all of them to the nand. Then everyone can easy switch between what they prefer.

The HDD surely must be powered to also avoid data loss. Dreamcast games are really slow even on NES/SNES Mini, they should be really slow on MD Flashback. Anyway a PoC test will be cool indeed

Can some of you tell me the mounting usb folder path please ?

Oh another thing: during the dump no other app is opened so it must be managed by the original AT "launcher" itself.

About the cartridge slot what i could do is make a section on my frontend. But it would be necessary to scan everytime you replace the game manually cause it will be stored in a database. I could hold the entry so if you put it in again its still available without rescan..

this may vary depending if you are using a hub, but in my case and im using the self powered mod:
"/mnt/usb_storage/USB_DISK0/udisk0/"

Thanks alot :-D im not scared to soldier it :-) got slot of training as im modding game consoles with passion :-P. But i guess the boards are identical.

my board does not have the rework on the controller unit. there are differences. just use a tester to confirm the 5v at the solder point

im really happy to see great development on the Sega flashback HD , my wife gave me one as a presents days ago but i was really disappointed with the choppy emulation on the games , cant wait to try on all this fine stuff you're working to have a better experience , thanks to all of you doing this and working in this.

Im sure you will be happy at the moment theres a release. I think the most important thing is teamwork so we can provide the best result.

And finally im on the way back home.. i found the time to watch some reviews about the mega drive flashback hd unit on youtube.. oh my god xD by watching these its no wonder nobody buys this system.. but to be honest basicly theyre right. XD XD... but now lets make it a useable system. Who in here wants to make a little developer group which works together and shares related informations? We can work together by swapping files, use teamviewer, email, one drive and make the system better than it ever was.

Allright everybody i performed the usb mod and it works. I can now finally proof and confirm that a external Harddrive will work on the SEGA Mega Drive / Genesis Flashback HD! A big thanks to Ckunak and WD_Gaster on showing how to perform this modification.. but even from my side one word of warning. The mod is not that easy as the wire needs to be pretty small.. be carefull and hold on for a second. Because if you failure, theres no more usb port which means no more hacking and modding for you!

The harddrive fits perfectly in the empty space of the mega drive, with this successed we can add nearly all Sega games from the good old days.

WD_Gaster · Jan 12, 2018

2TB is great or isnt it? To be honest im not interested to emulate other consoles than sega on the system.. but keep in mind the mega cd/sega cd library takes a lot of storage...

WD_Gaster · Jan 12, 2018

that being said, though for all the folks that are seeing our progress from the outside the usb mod IS NOT for the faint of heart and yes one short wire will fry the usb bus.
i had to use 30 gauge wire for mine and even then its hard.

also 2tb should be more than what anybody would ever need. i am laughing because that is AN absurd amount of storage which is awesome.

Basicly i would say the mod itself is simple.. but if you make a mistake .. youre done xD...

Yes 2TB is a lot, i guess we see how much is needed at the end. But for my full Retroshield project i work with 8TB and its nearly full.. but we all know the limitation of the sega flashback unit is big. We will see from which state emulations sucks.. but at the end if we can run dreamcast like at@games runs mega drive we can be happy LOL :-D

also on a silly side note, now you can load the genesis games for my dashboard off the usb drive as well.
if you click on the "usb" simbol near the bottom right. so far only loading games from "/Games/Genesis/" from the usb drive works but i will add support for game gear and master system off the usb in the future as well.

Amazing! Good work, this will make things alot easyer. I had alot of troubles by loading files into the mega drive hd.. i think this way is the best. Tough the main problem with this is that ppls require the 5v wire..
