Hey @Hekel, what can you tell us about Retroshield's arrival to our little nifty machines? Any news? We're so excited about it!

Hey i dont know yet. Basicly there is not much to do but i cant work forward cause my console is still broken. Nothing mentioned here has helped so far so i guess its propably bricked.

Brick can only mean an hardware fault unfortunately; in my opinion dued to some circuit shorts of the hardmod (those rockchip boards cannot be bricked via software in fact you can enter dfu flashing mode) so maybe a nand fault?

I "bricked" mine many times but always recovered it via backup reflashing.

I dont know what it exactly is but im not able to reload any dump i made before. But it did before so it cant be a fault dump.

Exactly, probably an unlucky hardware fault.

@Hekel maybe time to open another of your sega flashback HD, it looks like this would have happened anyway

asper · Feb 7, 2018

I tested LOT OF kernels and kernels+boots bricking many times (and many times recovering with a backup) but unfortunately the console won't boot. I just found out that also the misc.img partition seems to be "important" even if it contains just only zeroes... unfortunately rk3036 seems not to be a so common SoC so no specific firmwares seems to be available yet (if you find one please PM me !).

Another thing to add is that "Monkey King" chip can be an rk3036 revision built for atgames by rockchip so it can be slightly different.

If someone is good at linux-android kernel/modules recompilation contact me otherwise this project will be suspended for some time (probably months).

If someone is interested and has the necessary skills here they are source drivers for Realtek RTL8723BU, a WiFi+Bluetooth mini-device with usb support (already integrated for example inside Comfast CF-WU725B dongle): https://www.sendspace.com/file/7shwzc

If compiled for Android 4.4.4 on kernel 3.10.0 for rk3036 platform they can probably be used to support an external USB WiFi+Bluetooth device in our console. Here they are MD Flashback detailed system info:

Compiling infos:

All the patches seems to be included inside the provided archive which is freely available using google.

I am about to buy a sega genesis flashback hd and I am not computer savvy at all. I am a big sega genesis growing up in the 90s and I would like to bring back my childhood and play my favorite games and share it with my son. I know I can buy a nes and snes classic with all the sega games on it but I would like to have it on a sega genesis and I wouldn't feel right playing it on another game system. If anybody would like to help me out I am willing to ship my sega genesis flashback hd and pay whoever could put a list of my favorite sega genesis games on there.

Hey there, finally a new update! I Proudly present my Custom Original Dashboard!

As we know now there has been 4 different Region versions of the Sega Mega Drive / Genesis Flashback HD.

DE-Version
This version lacks of a complete menu. Its missing the Mortal Kombat section and the About section. It looks like ATGAMES released they‘re console with different games on the machine. The DE-Version is missing the following Retail titles:

Assault City
Astro Warrior
Defenders Of Oasis
Kenseiden
Kung Fu Kid
Mortal Kombat *
Mortal Kombat II *
Mortal Kombat 3 *
PsychoFox
SnailMaze
SuperColumns
TheNinja

*The Roms are still remaining on the system but it doesnt show up cause of the missing Mortal Kombat section.

The Game Gear Games haves all US-Covers, seems like ATGAMES preffered those. Overall i would say this is the most incomplete version that exist.

EU-AU Version
Those versions are basicly pretty simulaire. But the AU-Version contains a different Build of the main Dashboard APK. Both Versions are missing the About section and the following Bonus Games:

Bottle Taps Race
Break The Fireline
Chess
Fish Tank Live
Hang Man
Mahjong
Maze 2010
Snow Boarding
Warehouse Keeper

Seems like those Bonus Games are DE-exclusive titles. Those Both Versions has aswell the US-Covers for Game Gear Games.

USA Version
The USA Version contains the complete Dashboard. But its missing the same Bonus Games as the EU-AU Versions. The Covers are all region related.

This Custom Dashboard contains all games and fixes some covers. And for sure it unleashes the full Dashboard with all Features! I think it will not be allowed to put a download in here as it contains licenced material. But i will soon post a link on my YouTube channel.

Regards
Hekel

Hi Hekel - will you still be posting the batch files to perform this conversion? Also I guess work on RetroShield is stalled for now until you can get your console working again?

Not a lot of movement lately

It'd be fantastic if @Hekel or someone with the same knowledge gave this machine the quality it deserves. Don't leave us dealing with AT Games' incompetence, please!

Beetch18 · Feb 16, 2018

Anyone know a quick easy way to delete the save states? Someone said holding the menu key down for 5 seconds when in the launcher. I'm not exactly sure what the launcher is. I've tried this at the main menu screen and the system did reboot but there was a message it was restarting to initialize the wireless controllers and the save states remained after the reboot. I also tried during the boot up screen (which displays the at games logo) but no success. Thank you!

I pretty much gutted my American Genesis HD. I kept all electronics and connections intact. I'd gladly ship the insides to you if you could use it.

The device was built with a certain aim in mind, we extended its purposes. I do not see "incompetence", just businness

A matter of opinion... To me, a €100 console that's unable to run its MD/GEN games included without frameskipping (or freezing issues), or emulate the original console accurately (Real bad sound on Sonic 2 or Eternal Champions and graphical errors on Sonic 3D's bonus stages)... not to mention some original carts not even working on it (Sonic 3, Gunstar Heroes...)...seems the result of total and utter incompetente.

Nintendo's charging way less for SNES Mini while offering a way more solid emulation quality. Nearly everything works perfect out of the box.

Including more games is cool and all, but to me the main priority is achieving emulation as close as an actual Mega Drive as possible. AT Games isn't offering that

the console isn't super expensive so I'm willing to over look some frame rate issues. I'll even give a pass on the console freezing occasionally. However, where I draw the line are games that are unplayable. On my console I can't cast a spell without shining force 2 crashing. To me that's unacceptable

game compatibility will always be an issue with emulation. it should be better than it is though.

Menzo1986 · Feb 19, 2018

if people don't like how games play with an emulation system then you should buy the original system with the original cartridge game.
for me the mega drive flashback is just like the nes and snes mini.
al the system are great. nes and snes bit better but mega drive flashback also work fine for me.
the only thing for me is that all the systems are missing some great games.
for example the flashback is really missing the street of rage games or outrun.
but you can hack all the systems and add the missing games.
too bad they aren't on the system when you buy it but i can add the missing games so all 3 the emulation (nes,snes,mega drive flashback) systems are doing the job for me when i've added the missing games.

Let's be clear and not mix terms; Being emulation isn't the problem, but the emulator it comes with being horrendous. As @Hekel already demonstrated, Retroarch+Picodrive core offers way better results with the same hardware. What I'm trying to criticize is offering BAD software on a hardware that's more than capable to emulate properly (Again, Nintendo is offering good quality emulation with its Minis while being cheaper on top of that).

I insist, Megadrive Flashback is unable to play its included games properly not because of emulation or the machine itself, but because of a poor choice when it comes to what emulator AT Games put on it.
