switchable UltraCIC II for legacy ED64

EDIT:
you can modify your ed64 with this ultracic patch, so it doesn't need cracks for 6105 games.
that's why i renamed it to UltraCIC II, so there will be less confusion. ^^


This is my switch patch for jesgdevs UltraCIC.
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 between vcc and gnd

greetings,
saturnu

Here is an archive, that helps you to patch and create the flash binary. ^^
i've included avrdude, but you can use whatever you want
maybe there are some ponyprog fanboys here?
http://www.lancos.com/prog.html


Download:
https://a.pomf.cat/bxtstz.zip



1. put the UltraCIC.asm from the assemblergames thread in here
2. click on step1_create.bat

Flashing with avrdude and usbasp:



3. install the libusb0 driver http://sourceforge.net/p/libusb-win32/wiki/Home/
4. click on step2_flash_usb.bat if you are using an usbasp programmer


if you flash a new attiny, the internal osciallator is active and after the first ultracic flash it's fused to external clock.
depending on your programmer you need to clock the attiny on pin2 for reflashing.

UPDATE:
USBasp wiring

avr isp6pin header


USBasp isp10pin header

if you don't have a banjo tooie or jet force gemini rom, you can now use this testrom, to test your ultracic installation.

By the way.. it's a good thing you were talking about Ultracic saturnu !

It seem the Chinese struck again :

[saturnu]

I know that they are buyable since quite some time, but it was an open source project by jesgdevs and you guys should at least have the option to build one by yourself. ^^
...and patching assembler code isn't everyones darling.

[GreatFunky]

I was surprised when i discovered these chips last week ... The Chinese don't waste their time!

[saturnu]

very cheap usbasp programmer:

keep in mind, that if you want to reflash an existing ultracic, it needs to be clocked.
so you have to add an external clock or flash it in circuit while the n64 is running.

[GreatFunky]

Hmmm saturnu , with your new update .....  I feel suddenly people more attracted by attiny 's programming  than buying the Chinese one... lol 

[saturnu]

btw. there is a pic based ultracic, too ^^
https://github.com/mikeryan/UltraCIC

if someone needs to get this puppy runnig, there is some dau protection in the code ^^
feel free to ask here, if you have problems with that

[rafaelalvesals]

Could you make a step by step with pic or a vid pls? I'm trying hard to understand all this, but its sounds like greek to me  (i dont know if this expression makes sense in other countries than not brazil, sorry if dont)

[saturnu]

sure ^^

[skaman]

I get "Hunk #1 FAILED at 1." when trying to patch UltraCIC.asm.

[saturnu]

hm i have to boot into windows to check it myself, maybe i patched against another Ultracic.asm ^^

if you are trying to overwrite an existing ultracic, you should definitely take a look closer to check if it's really an attiny25 ^^
e.g. if it's an attiny45 you have to alter the stack offset.

and i don't know if the switch is labeled in reverse afterwards :>

[phoenixdownita]

I will really rock if Krikzz would offer this ultracic with adapter for sale separately so we can all use them and be done with patching and all the nonsense.

[saturnu]

hm, the ultracic everdrives have smd packages, so it's easier to reflash them instead of swapping the chip.

the older ones need to be resoldered and i think everyone who can swap a chip on a pcb can flash a micro, too. ^^

but sure, it would be a nice service to be able to buy prepared and tested chips.

[saturnu]

EDIT:
i moved this post to bottom of the first post, to keep the thread tidy. ^^

[saturnu]

here is my ultracic adapter, i was using while testing
it's not really necessary to desolder the old cic, you can just disable it, too
(if you are unable to desolder for some reasons or missing tools)
