Debugger problems
It seems that the debugger was corrupted. The start new pc option was false and it won't run because it can't find the bios.
You need to set the disk image(s) and boot device, either via the command line or using the menus, then select "create new PC" in the actions menu. You can then control execution via the "run" menu.
the issue is failed to load Bios java.lang.nullpointer exception. will try again
I finally got it to work with the Parameters of the makefile. Is there anything special about the Images ? I've tried using the Images from copy.sh/v86 but they didn't boot. Does it require more than the signature 55AA at 0x1FE? Do i need a whole boot record ? Anyway best i've seen so far !
