Vexed most likely uses the APD (Automatic Power-Down) buffer. Since, Game
Wizard uses this buffer for its interrupt routine (best place in the calc
for it), any other program using it will cause the calc to crash. Game
Wizard requires 257 bytes of memory at specific locations in memory.
Since, ASH v3.0 came out, everything moves about in memory. This means
that the APD buffer is the only "safe" place for the interrupt routine. I
could put it elsewhere, but if any part moves, the calc will instantly crash.
For programmers: I will be releasing a way to detect Game Wizard v2.0 and
the places in the APD buffer that you may use safely without crashing the
calc.
