Comment (by csnover):

 OK, so I guess what is probably happening here is that the GPU doesn’t
 support RGB555, which is the mode used by FM Towns. I’m unfamiliar with
 GPU programming so I’m not sure what options exist here yet to allow this
 to work (other than to convert in software, which is what SDL already does
 when you use the normal renderer). I’ll do some research when I have time,
 if someone else with the prerequisite knowledge doesn’t pipe in first with
 an answer.
