from ...

Thank you, marshallh! :)

Indeed, I find in the datasheet of AT49BV642D this table and the method to program this flash memory.
Can i use an atmega to program this flash memory as has done this man for his SRAM ( http://dev.frozeneskimo.com/embedded_projects:parallel_sram )?

Ive seen today a project called USBPROG that permits us to program nor flash memory like AT49BV642D.
I think i will use this flash memory to insert a n64 game (the maximum size of the game will be 64mbit).

Thank you for your information, marshallh ! :wink:

I would just try to find a method for people (and me) to replace N64 cartridges in the goal to continue playing on N64.

For instance, i find a method to replace ...

Hi everybody !

Otherwise, in the N64 cartridges, who is the microcontrollor that contains the ROM?
Because i think that it would be possible to replace this microcontrollor. Do you agree?

Hi everybody :D !

I'm currently creating my N64 portable.
For this project, I would like to replace my N64 cartridges by a system where i can use SD cards, CF cards or another removable device.

I've seen Marshallh's project called Flash64 that uses CF card but i can't obtain schematic and uC ...
