Work around a stupid PC-8201 bug that couldn't be found. For some reason,
in the Windows Release build, the ROM gets stuck looking for RS232 data and
waiting for SHIFT-BREAK to be pressed in the boot routine. If I try to trace
the ROM, the problem goes away, so it has to be timing related somewhere. I
found that simply adding delay by "debug tracing" each PC location fixes the
issue. The code below adds a 1-time debug hook during boot do add delay that
is later removed. This allows delay to be added at boot without adding any
additional delay (if statements) during the main portion of the code. This is a
horrible kludge, but it fixes the problem.
