d670c605a1 As it turns out, not putting 244µs between packets makes things unreliable sometimes; Nintendo was really saying that the interval between the start of two packets should be >=270µs, not that there should be a period of silence that long 2016-06-05 00:33:10 -05:00

fa4b6ae020 Ensure clock pulses occur at ~8192Hz 
Other changes:

    * Rip out checksum routine; it's a lot better to rely on the Game Boy
      Printer returning the device identifier and status bitfield to
      resend packets when checksum error bit is set

    * Ensure incoming value is read just ahead of rising edge (but I was
      already doing that so like yeah)

    * Ensure 270µs interval after packet transmission
