The MultiPlay allows to add two controllers on the expansion port.
It is easy to use them from BASIC, with the [[Locomotive_BASIC#INP_.28.E2.80.B9port_number.E2.80.BA.29|INP()]] command.

Each controller port can be set with two inputs modes:
== I/O ports ==
Port &F990 = Port A Actions bits
Port &F991 = Port B Actions bits
Port &F992 = Port A Mouse POS-X value
Port &F993 = Port A Mouse POS-Y value
Port &F994 = Port B Mouse POS-X value
Port &F995 = Port B Mouse POS-Y value
Ports &F996 and &F997 are unused
From a software point of view, just read the port and add its value to your position variable.
