The write method is now actually called when TR/TH level and direction IO port is written to. Also redefined the write method bit width (4) and document which bit is used for what. This will allow emulation of controllers which uses the TH line as a control output. This includes the Export Paddle, the Sports Pad, and Megadrive controllers.
This adds support for the Sports Pad, a trackball controller for Master System. Input is done using a Mouse or a trackball (best). Tested with Sports Pad Soccer and a homebrew test ROM.

It should be noted that under Linux at least (the only platform I can test on) the cursor does not move predictably without this also: #693 |

I forgot to ask you this on your last PR, but is the taito paddle controller for MSX similar to the sega one you already implemented for master system? |

I just had a look, and it is quite different. The Sega Paddle sends 4 bit nibbles and is self clocked. The taito paddle controller on the other hand is clocked from outputs controlled by the MSX, and data is transmitted one bit at a time serially... But this sounds fun, I will try implementing this peripheral for for MSX. |
