+# PS2 Joypad Server
+
+Use PlayStation 2 input accessories that cheap "PS2 to USB" dongles don't recognize by dumping gamepad input into UDP packets.
+
+## Building from source
+
+(Tested only on Linux)
+
+0. Set up [PS2SDK](https://github.com/ps2dev/ps2dev)
+1. Run `make`
+
+## Configuration
+
+- Set up OPL networking within OPL and save;
+- Copy the ELF to somewhere accessible (e.g.: MC1:/APPS/JOYSRV.ELF);
+- Configure FMCB shortcuts.
+
+## The client
+
+There must be a UDP listener at:
+- Same IP as configured in OPL;
+- The port for SMB in OPL plus 1024:
+    - If you used the default port 445, it'll direct UDP towards port 1469.
+- Capable of parsing and creating input in the system.
+
+
+### Known ready-to-use implementations
+
+ - [ps2joycln](https://github.com/adlerosn/ps2joycln)
+
+### Data format
+
+Expect 71 bytes per datagram. The last byte will always be a '`\n`'. Therefore looking like:
+
+`1006200079FFFF8080808000000000000000000000000000000000000000000000005A` - DualShock 2
+
+`2002200041FFFF0000000000000000000000000000000000000000000000000000005A` - 2011 generic Dance Mat
+
+After converting the trimmed hex string into a ByteArray:
+
+- 1st byte: where is the controller connected
+    - 1st nibble: Controller connected to port 1 or 2
+    - 2nd nibble: [unused] The slot of the multitap that the gamepad is connected to
+- 2nd byte: Pad state. Usable if either 2 or 6; unusable otherwise ([documentation on PAD_STATE_*](https://ps2dev.github.io/ps2sdk/libpad_8h.html))
+- 3rd byte: Pad read status. Usable if non-zero; unusable otherwise ([documentation on padRead()](https://ps2dev.github.io/ps2sdk/libpad_8h.html#a3ce97ac47e0c081994494f37280c0bcb))
+- 4th to 35th byte: [struct pad_button_status](https://ps2dev.github.io/ps2sdk/libpad_8h.html#structpad_button_status)
+    -  4th byte: `u8 ok` - zero is good 
+    -  5th byte: `u8 mode` - ???
+    -  6th and 7th bytes: `u16le btns` - bit array for digital input for buttons; 1 = released, 0 = pressed.
+        - The field itself stores little endian, but here I show big endian for clarity:
