Does Raspberry Pi output games at correct refresh rates to CRT?
« on: October 12, 2017, 01:27:03 pm »
For instance, if I want to play MAME games that run at say, 54.7 Hz, 55Hz, or 58 Hz, will Pi play them correctly? Does Pi output SNES games at 60.08 Hz?

In other words, does the Pi output games at their exact refresh rates, or do you get frame skipping/tearing/etc. because it runs a game too fast or too slow? Also, if you have experience with retrotink, does it output refresh rates correctly?

Currently, I use groovymame and output to either my arcade monitor or PVM - would the Pi give me a similar/same experience? Thanks.

Since you already have setups with Groovy and a PC, and you want that type of precision, you'll likely not be happy with Pi in general.
It doesn't have the emulation power that a PC does and due to its architecture you will have an inherent lag in everything...most people don't notice it depending on the speed of the game but it is still there.

Pi isn't for every gaming application, but it sure is good for lots of general gaming applications

SMB and Punchout on NES are two great examples where you can feel the limitations of Pi through the controls.

SMB runs fine on my Pi.
I did have to tweak some settings  to get it to run without noticeable lag though.

The guy who maintains the AdvanceMAME project recently wrote a version customised for the Raspberry Pi that provides the facility to play games at their native resolution and refresh rate, just like the original PC version of AdvanceMAME did.
