/**********************************************************************
- Sega Master System "Paddle Control" emulation
+ Sega Mark III "Paddle Control" emulation
+
+
+Release data from the Sega Retro project:
+
+ Year: 1987 Country/region: JP Model code: HPD-200
+
+Notes:
+
+ The main chip contained in the device is labeled 315-5243.
+
+ The Paddle Control was only released in Japan. To work with the device,
+ paddle games need to detect the system region as Japanese, else they switch
+ to a different mode that uses the TH line as output to select which nibble
+ of the X axis will be read. This other mode is similar to how the US Sports
+ Pad works, so on an Export system, paddle games are somewhat playable with
+ that device, though it needs to be used inverted and the trackball needs to
+ be moved slowly, else the software for the paddle think it's moving backward.
