ED64 Mempak uploader

Hi ED64-Fans,
i created a little Mempak-uploader based on libdragon - nothing new but the old ones don't work on my ED64. ^^
yes i know to select only single notes instead of overwriting would be cool... maybe next time

Greetings, saturnu

N64 (Dexdrive) to MPK fileconverter (dosbox is needed on win7 to run this)
http://n64.icequake.net/mirror/64scener.parodius.com/tools/memconv.zip

 

I'm a newb here. This allows us to put game saves ONTO a mempack?

 

this allows you to overwrite your real Controller-Pak with filename.mpk files or Dexdrive filename.n64 savegames if you convert them first to the mpk format.

 

I need the opposite then. A way to transfer save game files to SD card or PC. I can't bother with dexdrive as i don't have a serial port.

 

hm maybe that's doable through the cart-savegame files and a converter on the pc-side, for the ED64 sd-interface there aren't much information released. ^^ so that's the main problem with that

 

I hope KRIKzz will help us on that. I don't want to lose my saves on the controller pak one day. I wish to be able to store them somewhere safe.

BTW does your program wipe all save data on controller pak and rewrites it with the content of the .mpk file or just add the content of the .mpk file to empty slots. I think the first is true though i wanted to confirm.

 

yes, it replaces all data but it's not a big deal to add support for single notes, i already experimented with that. ^^

 

It would be a good feature to be able to use downloaded game saves for controller pak games. Currently it can only be done for games saving to the cartridge.

The ultimate feature would be to be able to back-up game saves too.

Currently there are two solutions for backing up controller pak saves AFAIK

1)Dexdrive. Cons:It needs a serial port and having hard time to work with new OSes.
2)Adaptoid USB adapter. Cons:Too expensive, over 100$

 

some information about ed64 sd interface: http://krikzz.com/pub/support/ed64/ED64-IO.zip

 

cool, thank you Krikzz ^^

 

hi, i did a little bit of testing with the IO. it looks like there is nearly everything included to read from the sd.
i used the error.h and types.h from the super-everdrive and added some missing stuff and i wrote a new sleep() function that is missing too.
the sys.h doesn't seem to be very important for the IO.
dma_read_s(); is now the last function that is really missing in the ED64-IO.zip.

but the the main problem is that if i try to read from regs_ptr[0]; it hangs/freezes instantly.

i tried to get the firmware version with 'firm = evd_readReg(REG_VER);'
and the initial function evd_init(); hangs at val = regs_ptr[0];, too

and btw. did i have to initialize the everdrive again or is the fpga still in sd mode after the homebrew is loaded. ^^
or are the registers locked with evd_lockRegs()?

sorry for that many questions
i hope krikzz or someone else can help me to get bit further

greetings, saturnu

 

Regs is locked when you start your code, but should be enought to write unlock value to KEY reg. regs_ptr[REG_KEY] = 0x1234;
I included sys.c/h, types.h and reload archive on server. Probably your code hangs cuz your types.h contains wrong definations

 

perfect! big thanks again ^^

EDIT: ok i wrote my first Controller-Pak backup onto the sd card i think the mempak backup/restore program is getting closer

 

Would be possible for a mempak emulator to avoid using the hardware part at all?

Save and load direct from the SD card?

 

i think if you write a prepatcher that replaces the save functions of each game with an altered one that saves to a file it could be possible...
sounds like a nice project for someone with a lot of n64 dev-experience^^
