Sega Megadrive Portable

When there is flash eepromchip so it is possible to upload there new homebrew game or demo.
But probably there is no linker yet.

I posted this info for people, who might want to build such 'linker'.

PS->I found this color variations.

It's not only color variation, but different revision of console. Silver is later one, with better sound and some other problems solved.

Fonz thought that these Flashes on the carts are burned with 22Volts thus making them most likely unflashable...

First, we must try reflash to know this exactly. Second, this carts uses standart flash chips, so even if flash chips in these carts is non-rewritable, we can remove chip and replace by new one - at least we can reuse circuit board and cart case.

Magistr Drive II made by Russian company NewGame (www.newgame.ru)...

'Newgame' not made any consoles, they just distribute it. I pretty sure that this consoles produces in China.

I guess the MDP comes from the same company...

No. MDP solds by 'Simbas', another well-known local distributor of unlicensed consoles and stuff.

Unfortunately, Simbas has no reseller in Estonia... I would gladly get some MDP Oh, and the hardware New Game sells is indeed made in China... I just read the "sledalo b kitai"(or something similiar), means "made in China" for people who understand Russian less than me...

Fonz thought that these Flashes on the carts are burned with 22Volts thus making them most likely unflashable... my MPCP could be used to re-flash them, but there is a need for 5V to 3.3V converters (or power the MPCP with 3.3V, but then the PC LPT port would kill it maybe).

Just use 200-400 Ohm resistors in series and it will be ok

@Shiru -> So grey one is better to buy??? (I am interesting only in soundchip...)

Wow nice news!!!

I am hardware newbie but I think homebrew LPT "linker" + re-flashed original cartriges will be best choice for start homebrew on this /demos,home coded games,vgm player.../.

Maybe later when will be architecture understanded then will be possible to add some micro-sd ,usb - and make some opensource PCB etc etc...

But first step will be build simple "linker"+re-flashcartrige (original) cartrige...

Wow maybe when homebrew will be possible at this handheld ,will be ideal for YM2612 FM-Music producing/player like on gameboys with some kind of sequencer/tracker/player...(In far far far future )




I like chipmusic not games...

MPCP is right here : http://www.hot.ee/tmeeco/DWNLOADS/MPCPSHIT.RAR

I haven't updated it though... I have utils to writes flashes now... but I need to figure out some "scripting" system to support all flashes with a single program. I use it to dump my MD carts and reflash my Flashcart and write to my SRAM cart... and manage my code locks and be just a nice piece of equipment on my desk

My design is full CMOS and when I put resistors on the data lines, device to cart way would work, but the other way might not (the 3.3V level signals from the cart get lower and CMOS chip might not see "1" anymore)

Oh, and LPT port is TTL, so it won't fry the MPCP when I power it with 3.3V... my LPT ports high output level was only near 4V or so...
