I wonder if it's possible to fix/flash the cart, and fix the C5...

I would really like to test the altered values to see if I'm correct but I don't have a chip programmer and the chip is a SMT.

My soldering skills rule out me being able to remove, program and replace a SMT chip. I don't believe it can be reprogrammed in place.

Where's all the late 2013's excitement around this project gone ? :'(

I think once people got the carts and discovered it was pretty lame that the excitement vanished.

I think there is an arduino inside and that it can be flashed normally

I could do it if I had a cart. PLCC's are fairly easy.
If someone wants to send me their cart with the corrected rom, I would do it for free.

In fact I contacted Jarek, and he told me that:
* the Chip Maestro is powered by an Atmega168 chip, supported by a low-power CPLD
* all the source code is available
* to flash the C M, we need these tools:
  1. Small screwdriver to open the Chip Maestro
  2. USBTiny ISP (i prefer the one from adafruit because it works in windows 8)
  3. 6 Pin Tag Connect Cable ( http://www.tag-connect.com/TC2030-IDC ), you can also solder wires to the programming pads if you're handy with an iron and want to save 40 bucks.

I opened mine up and took a look, I can see the ISP and JTAG headers.

Unless I am missing something this might do the job for me

Those pads look a bit of a pain to solder to but if I took my time I could add wires to them.

Please keep us updated if/then you are able to reflash it

So in which component is the hex data for c5 stored?

It is listed in the Channel.h file from http://www.soniktech.com/chipmaestro/as … troAVR.zip

Oh thanks. In that case, anyone should be able to flash a new value for c5.
