Dreamcast and PS2 Cherrytrail/Apollo Lake setup

[dov_EL]

On youtube I see videos where they turn Dreamcast and PS2 on Cpu Atom X5 X7.
However, I can not find any way to have an ideal setting to run these machines this way.
Do you have any suggestions?

The atom cherry trail SOC have very weak graphics and very weak CPUs for emulation. In PCSX2 you are probably going to be forced to use something other than the software render, which is fine for a lot of games, but don't expect perfect emulation for a fair few of them. Intel graphics drivers in windows, in my experience, sometimes have problems, and a lot of those issues are not always well documented in the emulator wikis. You will likely have to do a lot of fiddling and configuration to get some games running really well. 

Demul is the dreamcast emulator I prefer. I believe it is a fork of the nullDC, so performance requirements should be the same. There isn't much in the way of settings of this emulator... you should set it to native resolution to start, as I doubt a higher scaling will run well on the hardware. You can get more ideas about how to improve performance here:

PCSX2 is a lot more flexible in this regard. Again you would want to try native resolution. I would enable  8bit encoding to save some CPU cycles, as it PCSX2 is generally more CPU bound. You can also fiddle with the more aggressive CRC hacks and VU cycle stealing on the more demanding games. You will likely have the best luck with 2d games, and you may have deviate substantially from recommended settings in the PCSX2 wiki. You might be able to find some global settings that work well enough for your games, but I would recommend instead to use the cfgpath argument to load different settings for each game. See the PCSX2 command line wiki for some examples:

You might also ask the youtube author to post some of their settings for the games they show in the video. That might give you some ideas as well.

Thank You !!

NullDC system requirements are much lower than Demuls

I didn't know that, thank you for the correction.

It's also no where as good as Demul which is sad because Demul isn't perfect either.

the problem is a setting , plugin  etc.
