Hardware > Anyone have the EZ-Flash III SDK?

#106223 - showka - Mon Oct 16, 2006 11:53 pm

Does anyone know how to read the flash drive portion of the EZ-FLash III card programatically from within a GBA program? This is the large portion of the drive, the 1024 megabyte portion of the cartridge.

Thanks, great link.

Unfortunately it appears you can't access the beefy part (the NAND) in "Game mode." The EZ-Flash III's OS has a game that's a mine sweeper clone - the way they did it, you'd think they'd have opened the door for other people to have made applications for the OS mode ala Pogoshell. Guess not... :(

Nothing's stopping you from having code in RAM switch back to OS mode, then read and write data, then switch back to game mode.
I have the impression that the EZ3 may use the FAT file system, so if you can read and write sectors, you could add the EZ3 to Chishm's code.

I think trying to read the FAT 16 file system would be too daunting of a task for me. However, I found this tidbit at the following wiki:

Quote:

The EZTeam released a software developers kit (SDK) that alows those who should so desire to make use of the PSRAM section and other non-standard features of the EZ3 see the article GBA for links to the SDK and development guides.


This seems about right. Anyone know where this mythical SDK is? EZFlash.cn is eternally down and seems to never work. I've also read forum posts throughout the Google waste lands that indicate that it was real and did exist.

EDIT: Changed thread title.

Found it. Never mind!

Hopefully it'll be workable.
