Hello,
1) First i have one question : I've never seen a spt1500 so i don't know
where the buttons are placed.... I wonder how it is easier to play Tetris
with a device upside down. I any of you can provide me with a picture of a
spt1500...
2) As previously mentioned here, one can imagine trap the all the drawing
primitives, and call the same primitive with (160-x,160-y) in place of
(x,y). Doing that for all primitive is indeed a "tedious" - copyright A.A
:) -job, but quite a simple mechanical task . Perhaps is there a low level
primitive (like a put pixel primitive) that is used by all the other
primitives (like draw line, draw circle, etc), so it can be trapped once for
all. Then there is the text display stuff to trap also... Then there is the
pen position stuff to trap, because you don't want only reverse the display
upside down, you also want to tap on what you draw, and get the right
answer.... Whooooo, would be an interesting hack!
Oohhh, and as the screen is a square, what about playing games with buttons
on the side, with left handed and righ-handed configuration! Once you solved
the first problem, allowing this is a breeze!
What do you think?
