Dreamcast (reicast) multiplayer split screen and rendering options

[korrok]

Hi guys,

I've tried several games with retropioe and reicast, it is trully great to play it again so smoothly with my rapsberry Pi3.
But in some games, as toyCommander or StarWarsRacer we need to split the screen to use the multiplayer mode. Unfortunatelly the screen goes black or blink with alternative parts of the games, thus the game becomes unplayable.

I've searched a little on the internet, and it appears that some features are disabled like clipping or some other rendering options. According to the githlub website those features have been disabled in order to prevent the game from beeing to slowed down by these rendering.

My question is, knowing how fast is the rapsberry Pi3 now, don't you think those features might be able to work now ?

If so, anyone knows how to activate it or remove the # lines in order to get it back after compilation or anyhow ?

I'm sure, i'm not the only one interested.
Regards,

I know this is an older thread, but I wanted to basically document what I've learned so far with respect to reicast and multi-player split-screen games.

Outtrigger on split screen works flawlessly, while Re-volt and Toy Commander have issues with player 1 (top half).. very jittery, and it can go completely black in some cases.

If I go to the reicast settings screen (after clicking +START REICAST in the ES Dreamcast screen) and change the 'frame skipping' option from 0 to 2, Re-volt and Toy Commander run fine in split-screen mode. There's a slight decrease in smoothness obviously, but there's no major jittering or blanking of the top-half of the screen. Also, I should note that both of these games run flawlessly when it's just one player (and that's without any frame skipping).

This is a recent version of reicast, updated 3 days ago with retropie_setup.sh.
