Carnevil lags

[Lucatort]

Hello I need your help.
How I can get carnevil works on rpi4 without lags?
Which kind of setup core I've to use with mame 2003 plus?
Same question for virtua cop
Thanks

@lucatort I don't have an Rpi4 and I don't have enough information to answer you perfectly.
But, have you tested it with MAME 2010 and/or MAME 2015 (and the corresponding romsets, of course)?
I can't say if this is the case, but MAME evolves its romset and some games work better in different romsets...

BUT, it's a pretty heavy game, maybe not even the RPi4's GPU is strong enough to run at 100%, regardless of the adjustments you make.

@zing thanks for your reply. I've tested in both version with some results. But I've read that someone play it without lag so I thought it's possible to have a good result with rpi4 too.
