PsX Twisted Metal 3/4 - 4 players not working

ChaosEffect

@shavecat @kounabi22 and to everyone else, the Twisted Metal games and Rakugaki Showtime work with 4 players in lr-duckstation when the multitap is set to "Port 1 only."

NFL GameDay 2000 also correctly enables its 8-player mode with the dual-multitap setting in lr-duckstation.

I think the recent RetroArch updates made that "maximum users" setting more important, so make sure that is set to 8 if you want to use dual multitaps (default seems to be 5).

@chaoseffect
Hey thanks
But i dont have lr-duckstaion (or even to install it on the retropie pi4)..

ChaosEffect

@shavecat From the EmulationStation menu, go to

RetroPie -> RetroPie Setup -> Update RetroPie-Setup Script

Let it update (shouldn't take long).

Then go to

Manage packages -> Manage experimental packages -> lr-duckstation

You should be able to install it from there. You can then switch which emulator a particular ROM uses by opening that ROM and pressing a button during the loading sequence to bring up the Runcommand window.

@chaoseffect

but the lr-duckstion just exit back to the retropie menu...

@shavecat I had some issues too. That happened to me when I didn't have a PS1 BIOS file in the /home/pi/RetroPie/BIOS folder. Do you have one? Duckstation seems pretty flexible with the BIOS you can use. You can use the same file for PCSX-ReARMed. I used scph1001.bin. You're on your own with obtaining that file, though.

@chaoseffect
Thanks
i do have the SCPH101.BIN file on the bios ofucrse PCSX-ReARmed works prefect ....
just did a rest maybe it will fix it ? :O

ChaosEffect

@shavecat Hmm, that one is listed in Duckstation's docs, so I assume it should work. Maybe you do need to restart after installing. I usually just do that on habit. If that doesn't work, maybe try the 1001 version?

@chaoseffect
i do have it also ;)
if it wont work i will open a new ticket .
thanks :)

lr_duckstiaon
so the games still runing on multitap like twisted metal 4
but no 4players
only 2 :
tried to play with the multitap
enable 1/2 or both..
but still always 2 players

@shavecat When you enable the port 1 multitap, you have to restart the emulator to have it take effect. Probably the best thing to do is to save a game options file with multitap mode set to "port 1 only" so that that particular game always loads with the multitap on.

This is in Quick Menu -> Options -> Manage Core Options

Try deleting the game options file if there's already one there.

So, to summarize:

Start your game
Go into the RetroArch menu's Quick Menu -> Options -> Manage Core Options
Delete the game options file, if there is already one
Go back to Quick Menu -> Options
Set Multitap mode to "Enable on Port 1 Only"
I also Disabled "Force Analog Mode on Restart" for both player 1 and player 2 (not sure if this matters; I just wanted to avoid the pop-up message when the game loaded)
Go to Manage Core Options again and save the game options file
Exit the emulator as you usually would (Select + Start?)
Re-enter the game

Note that the Twisted Metal games only allow more than 2 players in deathmatch mode. Tournament mode is limited to 2 players max. Let me know if you have any issues.
