hi mate
thanks for the reply
but i cant find the manfacturer for this item
can these cards be read with a chip programmer
just a thought as i have a couple of dsd bad cards and thought i could erase them with a progger then read a good 1 and write that to the card
would this work or not
cheers

the processor in a ROM10 card is actually a derivative of the ST7 family m8, {the eeprom is anyones guess}--"the r11 will be diffrent again

assumeing you knew the actual chips on the card m8, "what makes you think you could read/erase them with a chip programer"------ if your card programer wont do the job then a chip programer wont either.

hi mate
i thought trying to open a program with a program would be harder than erase and rewrite (like a reformat i thought )
would this not be possible
thanks for your reply benny

rom cards need to be fully functional and open to erase/rewrite then m8, {you cannot reformat a rom with a chip programer }-------wipe a romcard and it will be useless m8

dont confuse a funcard with a romcard m8, {you can easily erase a locked fun but you wont do it on a rom the way your thinking}----------its a completely diffrent type of card-------get yourself an unlooper m8

r10 addresses
$0000 - $003F Processor registers
$0040 - $03FF RAM area
$2000 - $202F MAP Co-processor area
$4000 - $9FFF Card Firmware ROM area
$C000 - $CFFF Card Firmware EEprom area (for firmware updates etc)
$D000 - $DFFF Provider record EEprom area (for provider keys, PPV etc)

there's no public software that can fix the atr on a r10/11 m8, the other cards you might open useing diffrent scripts, {you definetly wont open them with a chip programer}
