Skateboard Peripheral

The Tony Hawk: RIDE \ SHRED skateboard is a peripheral that launched in 2009 for ps3,xbox 360 and wii

i have collected some info that i would like to preserve. this info was mainly used in this PR to RPCS3: https://github.com/RPCS3/rpcs3/pull/14619

The game looks for data in cellPadGetData and cellPadGetInfo2.

For the game to detect a controller as a skate board the data in cellPadGetInfo2. needs to be:

now_connect = 1 (is the controller connected)

system_info = 0 (??? never seen it not be 0)

port_status = 1

port_setting = 6 (set by the game by calling (cellPadSetPortSetting(port_num, 6) )

device_capabillity = 7 (describes that it has motion etc)

device_type = 0 (no idea)

cellPadGetData is a function that is called when a game wants to get input from a controller. it ruturnes an pointer to a padData structure.

typedef struct CellPadData {

    int32_t len;

    uint16_t button[CELL_PAD_MAX_CODES (=64)];

}

inside the button array we have 64 bytes. ill explain them all in the context of the skateboard

in summary. for the game to recognize a controller as a skateboard it has to have this:

bytes 4 and 6 have to be 128

bytes 16 and 17 have to be more than 5 and less than 55

that will pass the is skateboard connected check

now you (sadly) have info on this plastic piece of shit

it was fun to understand it and now rpcs3 picks it up :)

heres a bonus image of a prototype board:
