Megadrive handheld, H&B, FusionCore...

Post by KanedaFr » Tue Jun 22, 2010 8:28 am

Hi,

it seems there were a lot of release of megadrive clones while I was...elsewhere
from what I read, it's mainly emulation based...and so, sound is ugly...
which clone is the closest to the original genny ? and work with original cart ?

Most all of the "new" clones are all "Firecore" based... the same old ARM-based SoC with emulation, but can run "native" games off SD card with a special cart called the Passport. Most take regular SEGA carts, but the Gopher doesn't, going for a slim case and having the SD interface built-in instead of as an option.

Of the handhelds, the two that use actual carts are the RetroGen and the GenMobile. The RetroGen has a cheaper case, and no built-in Genesis games (it does have 20 built-in "native" games that all suck). It also has a bigger LCD display. Some people don't like the "disc"-style dpad, but I don't mind it.

The GenMobile has a fancier case and looks nicer, but uses a smaller LCD display - small enough that it's hard to read the text in some games. The dpad looks more traditional, but is split in two pieces, which some people claims makes it harder to do two of the diagonals (the ones across the split). It has 20 built-in Genesis games, as well.

The display is good on both, but the RetroGen is better with its larger LCD. The sound is okay, but the pitch is rather low on music. Both have the ability to do TV out and come with an AV cable. The RetroGen is recharged via USB cable, and comes with one. The GenMobile also uses a USB connector to recharge, but comes with an AC adapter with a USB port connector.

Both carts seem to be based on the same hardware, performing identically in emulation. The speed can lag a smidgen in some games, they have identical graphical glitches, and the same bad audio. The only flash cart to work on these is the MD-Pro. The MegaCart and Everdrive-MD aren't even recognized, and the Neo Myth fails unless you plug a 5V battery pack through its USB port to power the Neo Myth separate from the handheld.

wow! thanks Chilly Willy!
Great informations!
does the retrogen is similar to the PocketMD I own?

I personnaly saw today an H&B megadrive on a french supermarket for 30€
It was very strange to see this "megadrive" metal logo on a 'new' console :)

Also we have Megadrive Portable, wich has small size cartrige. In fact, MDP cartrige can be connected to Megadrive/Genesis and vise versa via simple adapter. Standard Megadrive/Genesis cartrige and MDP cartrige differs only by size and pinout. It's has website (in russian, sorry). Does MDP use an emulation or not, I don't know, but on some models we can see Altera FPAG's and JTag interface. It's seems like a hardware emulation. OK, some pics now:

I think the GenMobile is more similar to the PocketMD... look at these images to see for yourself.

RetroGen playing one of the better native games built in: http://www.pocketgamer.co.uk/FCKEditorF ... ro_Gen.jpg

GenMobile playing Sonic: http://technabob.com/blog/wp-content/up ... rtable.jpg

I have both, so if you want to ask something specific, I can probably give you an answer... other than when they plan to release the Passport in the US. :) Currently, the Passport is available only in Germany and Brazil (I think).

I have some clones here, PocketMD being one and Hamy Digital Genius with 19 games inside. Both use a TecToy TCT-6703 ASIC so in theory it should be compatible with anything, but the machiens only supply 3 or 4V to the carts and flashcarts tend to want a bit more than that.... my barebones flashcart with nothing but 2x flash chips inside won't run because the chips seem stop working at below 4.5V...

In fact, I was looking for a way to test game "right from my PC"
I can't install all my stuff on the TV room, asking my wife to stop watching TV while I test my 'ugly' game :(

I wonder if my SMD will work a PocketMD....need to make an adapter to test...

Got another idea...let's go for another thread.. ;)

Why not to buy a TV tuner then? In this case you will have console close to your PC and will see it's output in a window on the same screen. Yes, it has worse quality than actual TV, but it is comfortable (you can even record a video or take a picture), and the quality is high enough for testing.

The Everdrive should fit your needs (as long as you're using an original Megadrive or a clone that can supply adequate voltage). It uses SD cards and costs $65 including shipping.

KRIKzz made MD link via USB and joystick port. It has inbuilt USB-COM adapter, so you use it as COM port. I made many tests with this thing.
I've got maximum transfer speed of 81 KB/s.
He also told me about improvements of this idea.

Ok, I'm in.

Let's go for an everdrive and an EasyCap :)

Faster and easier than any hack and crash :)

I agree on the built in games, I think all of us could have written something better with our eyes closed :wink:

Did you notice - the new v8 OS for the Everdrive now allows homebrew from the SD card that can take control of the hardware (meaning you can use the SD card inside the homebrew).
