I anyone is brave enough to try them out I now have both JAvrProg and c0ntr0l up and running in OSX. NOTE: Only tested in 10.5.
Please let me know of any bugs with flashing the x0xb0x or saving/loading patterns from c0ntr0l. This is _not_ a fix for all of the problems with c0ntr0l, they will most likely never be fixed! Use it for flashing the x0xb0x and saving patterns to your computer, everything else is just not working.
First you need to install the USB->serial driver from FTDI:http://www.ftdichip.com/Drivers/VCP.htm
Then download the c0ntr0l package I made from here: http://x0xb0x.co.uk/Sokkan/files/c0ntr0l.app.dmg.zip
(the source is here: http://x0xb0x.co.uk/Sokkan/files/bkup2.zip
Unzip, doubleclick the disk image and drag the application to a convenient location and doubleclick it.
For JAvrProg you also need to install the 64-bit RXTX 2.2 prerelease binary package from here: http://rxtx.qbang.org/pub/rxtx/rxtx-2.2pre1-bins.zip
There is some install instructions in there for 10.5.
Then download the hacked JAvrProg I made here:http://x0xb0x.co.uk/Sokkan/files/JAvrProg.zip
Unzip it and type "java -jar JAvrProg.jar" on the command line in that directory.
IMPORTANT NOTE: They do work for me on my machine, but there is always a risk you end up with a x0xb0x that you need to flash with new firmware from a known working system.
