How about trying something like this?

  F0FE LDX #$3f
      0   load ldx opcode and prepare for write of $fe
      1   load $3f (maybe this prepares a write of $ff?)
  F100 NOP
      2   load nop
      3   ???
  F101 LDA #$F800
      4   load lda opcode
      5   load low byte from $f102  (poke?)
      6   load high byte from $f103 (poke?)
      7   load from $f800 (poke?)

Now, inspect f102, f103 and f800 and see if one of them contains
$fe (or maybe $ff).
