I recommend that you use the latest SVN builds for PCSX2, they fix a lot of things that PCSX2 officially has problems with, and there have been a few fixes for Ico during the time between the official release and the SVN release as well.
I've put down the money on the Odin 2 Mini since I just love that Vita form factor. Loved the power of the Odin 2 but the size always put me off, this one seems exactly what I've been wanting.
On the go tho I meant, I use my 10" tablet and a Bluetooth controller for retro gaming while sitting on my porch or on long car rides sometimes. Easier on my eyes than the Switch screen.
Ken unless the games are made for that screen size most suck on a screen that size... Having a square screen and being brighter and higher res helps but it's not a cure all, text is tiny bullets are tiny, your.... Well lol
