Hi!

Yeah, JPCSP supports it, and on the other hand, last time I used it(months ago, so it's probably changed), it has no onscreen keyboard at all; it just brings up a dialog box asking for your input.

Here's a summary:

PPSSPP:
+Onscreen keyboard
-Can't enter input with a physical keyboard

JPCSP(keep in mind my current knowledge of it is like 4 months old or more):
+Can enter input with a physical keyboard via a messagebox/dialog box
-No onscreen keyboard

Pretty much opposites of each other.
