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.

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

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

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

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 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.

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.

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.

What are you basing that off of? Is that just a wild guess?

Also I've seen that http://chipmaestro.com/ is online. I wonder if they updated the code in the version that they sell.

I was just looking at the code that the developer posted. It has the value for C5 being 00D2 in Hex this converts to decimal as 210.

Using the equation to get the decimal for the notes it is (CPU speed in Hz/(Note Frequency * 16)) - 1
1790000/(523.2511306*16) - 1 = 212.8074692198286 this should be a 00D4 not 00D2 as it is showing under NTSC static int noteTable[128]

The PAL looks like it is out as well for C5 1660000/(523.2511306*16) - 1 = 197.279552461 which would be 00C5 but is showing as 00C6 in the code.
