Seems like the problem is our cartridge ... when GEMDOS HD (or VDI
resultion) is enabled, Hatari simulates a ROM cartridge for simulating
the additional features. That cartridge likely does something that is
not supported by TOS 0.00 yet -> crash -> reboot.

So the fix was easy: Simply do not use the cartridge when TOS 0.00 has
been selected (does not make sense anyway since this TOS does neither
have a GEMDOS nor a VDI).
