I stepped through the code....it is doing something really strange.  
When it gets to the last instruction (out   TCNT0, r31 which is at 
address 0x16) it jumps to 0x17 (which is one byte past the last 
instruction in the code, per the mapper) issues an "unsupported 
instruction:  muls", then jumps to 0x18 and issues "unsupported 
instruction:  mulsu" then jumps to 0x01f7 and issue an "invalid opcode: 
0xffff" error, then just kleeps repeaing that...the trace using F11 
doesn't show anything happening at all.
