Some ScummVM games won't work, why?

[KYPerry]

I can't get some ScummVM games to work (on Android), and I'm not sure exactly why. The games that won't work are:

Arthur's Computer Adventure
Freddi Fish 5
Spy Fox 3

I'd like to know why these don't work, as all the others do. Thanks in advance.

In what way do they not work?

Can you not add them, do they add but not play as in when you hit load/run they load a black screen, do they run but freeze up or glitch in some other way?

Arthur's Computer Adventure brings up a functionless debug screen. The other two show a "colour" problem message.

Port incompatibility

I will test those ASAP though on my Tablet
