it’s not a “nothing special” device, it literally has a psp encoded into the soc package…

It’s nothing special anymore today because current arm processors are fast enough to fully emulate PSP, unlike the time when vita was still in development.

this is just flat out incorrect, a huge amount of games just don’t work on the vita tv because of the lack of touch interactions

Only a few dozen out of hundreds of vita titles, and mostly due to the lack of touchscreen, not the lack of the rear touchpad. Most vita titles that use the rear touchpad only use it as a workaround for the lack of R2/L2 buttons (and many of them already patched to recognize R2/L2 on vita tv), which the portal has. If the portal has vita support, it’ll support more titles than vita tv simply because it has a touchscreen.
