Port Binds

mitu

This shows both P1 and P2 have the same gamepad. It's the mouse index that you're changing or you also chang the Device Index ? I don't see any mentions to a Dolphin Bar, but I guess that may be the DragonRise controller ?

Jezza

have not changed the device index, have not needed to
All controllers are DragonRise. [EDIT] dolphin bar and trackball do their thing whilst set like this

Jezza

DragonRise controllers are the standard controls for each player

mitu

Then what exactly did you change - and it's not saved ?

Jezza

Port 2 Binds = mouse index 3

mitu

I thought you're just switching device order - the mouse index doesn't look like it's part of the remap file.
Create a .cfg file for the game (<GAME_NAME>.cfg) alongside the ROM file and add to it

input_player1_mouse_index = 0
input_player2_mouse_index = 3

See more details about per-game configs in https://retropie.org.uk/docs/RetroArch-Configuration/#config-hierarchy.

SOLVED
once again Mitu, THANKYOU

this setup works so well because player 1 can use the standard controls or the light gun + player 2 can use the stick or the trackball with standard buttons as the shoot / grenade !!!!!!!!! much the same for all games
