There is a problem dumping 'right cartridge' carts with the version of Maxflash Studio that is on the current CDs.
You can download a new version here:

There is a pointer mistake in the code for dumping the 8k right cartridge in the user application portion of the program. On all systems except W7-64 this just causes a popup application error and the application will close. For some reason Windows 7-64 thinks this is such a hazardous condition it forces a BSOD with the code "SYSTEM_SERVICE_EXCEPTION"
Updating the application package will solve the issue. A firmware or driver update is not required.
