hi all, this is ozkan from Turkey, I just try to flash megadrive game to my flash cart but it does not , I tried test flash with diognostic V1.5 it starts then it stops around %10, I test it with 2 computers and 2 cables nothing change, is my flash card is broken ? thanx for your help

[ozkano]

I think MD-pro 's flash chip is gone E28F640, where can I get one or can I install a new one with high capacity for example 128mbit or 256, Tomy how many years it has fixing guaranty

[ozkano]

I did a little search for this chip but I could not find at local electronic component sellers, the only thing I found is 28F160 that means 16 Megabit, so 1MB version, right now I dont know what to do, I will check my broken boards to find this flash

Tomy I am waiting your help

[ozkano]

does 28f128 works if I found one ?

[kyuusaku]

I don't think your flash is dead. If it were, you cannot just put in a 128 or 256Mbit flash and expect it to work.

[ozkano]

so what can be the problem,there is bad sector on flash and gives error while writing on flash cart

[ozkano]

if I found a new 28f640 it wont work either, as I read from articles there is non writable section on this chip and this one is for registiring it self to hardware, does anyone have any information about this flash how can I read my broken flash boot sector and write it to new one or you say forget and send it back to tomy

[kyuusaku]

Is this a brand new MD-PRO? If not, have you used it successfully before? I suggest you send it back to Tomy and not damage it with other Flash which I'm sure won't work. Please realize that each brand of flash may require a different programming algorithm, perhaps you aren't using the correct Dreamwriter for your particular flash. You should talk with Tomy before anything!

[ozkano]

approx, I bought it 1,5 years ago, I am using up to now, I tried 1.6 and 2.1 nothing change

You might have fried some parts of the cart with static electicity...

For exemple, puting some plastic tape on the circuit board can fry the cart.

Or just put the card pcb on any plastic/metal/synthetic (non-wood or non-grounded) surface can immediately fry the card.

[ozkano]

I used it with the plastic cover which I remove from an ordinary megadrive game

[ozkano]

today I did something and write error disappear but games dont work, I flash games or game to flash card and verify it and no errors, but when I insert my multimega games dont work,
