N64 CIC, looking for 710x series info

I've thrown the file jesgdev sent me up on Dropbox for the time being: https://www.dropbox.com/s/vn72jkqezi30792/fpjhhh.zip?dl=0

 

With a functional CIC clone, we really only need a versatile maskrom to create a proper flashable repro cart, which would be awesome for homebrew and romhack distros. Really the only other thing we need are moulds for making new cart shells.

 

what is the pic you used

 

ATtiny25, like the header of the source and fuse map picture says

 

Hi,
Is the code available for download?
Thanks.

 

All the links for this are dead it seems.

EDIT: This is the closest thing I found.
https://github.com/mikeryan/UltraCIC

 

I would love to do this mod

 

does anyone have the fpjhhh.zip file
i've been searching the google like crazy every link is broken..
the ultracic doesn't have seeds or checksums and is also PIC micro based

the seed looks like its only a byte so.. 6105 seed is 0x91 and checksum is 0xDF26F436?

still looking for that zip file

 

It was all archived when pomf.se went offline, just need to change the https to http. I updated the link in first post.

 

This is my switch patch, that i orignally have posted on another forum. ^^
plus some pictures and info, about compiling and flashing the UltraCIC on linux.
(or on windows with open source tools instead of Atmel Studio)

The source has been modified to work with avra



The Maskrom is directed to the back of the console.
The switch is in NTSC mode, if PIN3 connected to VDD and in PAL mode on GND.


N64 CIC Pinout


UltraCIC Pinout (ATtiny25)
PIN3 connects to the switch



patching
UltracCIC.asm has to be in the same directory

Code:

patch < UltraCIC_avra_switch.patch

http://gnuwin32.sourceforge.net/packages/patch.htm

compiling

Code:

avra UltraCIC.asm

http://avra.sourceforge.net/downloads.html

flashing
low fuse 0xc0 high fuse 0xdf

Code:

avrdude -p t25 -P /dev/ttyS0 -c ponyser -U lfuse:w:0xc0:m -U hfuse:w:0xdf:m -U flash:w:UltraCIC.hex

There is a vendor (SuperUFO Company) on aliexpress.com selling UltraCICs in a compact design - switchable between NTSC 6102 and PAL 7101.

http://www.aliexpress.com/item/Ultr...E-64-ED64Plus-N64-Flash-Cart/32431977887.html

 

this costs $5.99 and the switch is pretty much unreachable, if you don't want to make a hole in the back of your shell.
an attiny25 costs about $0.90
even a usb programmer only costs about $1.69 from china.

i would only recommend this, if programming an attiny25 seems like witchcraft for you.

programmer:

btw. if you want to use this programmer you have to set avrdude to usbasp
flashing

Code:

avrdude -p t25  -c usbasp -U lfuse:w:0xc0:m -U hfuse:w:0xdf:m -U flash:w:UltraCIC.hex

 

thanks for the help everyone i know how to read avr code the pic is kinda cryptic to me lol .. wish i didnt waste so much time on the google now
i'm interested in looking at the original code. are the dumps or disassembly available?..

 

Anyway you can post a compiled hex?

 

i don't think i'm allowed to publicaly share a binary with the keys inside.
thats why i'm only posting a patch. :>

there is a win32 port of avra too, if you don't want to install atmel studio.
http://sourceforge.net/projects/avra/files/1.2.3/avra-1.2.3-win32.zip/download

and here is a windows version of patch
