im cloning supaplex for calc, and as you can see in this screenshot, im quite far:
(this is fast mode, the actual game is slower due to 4 added HALT's)
[attachment=2609:supaplex7.gif][attachment=2610:supaplex6.gif]
(ignote teh crappy title screen, im too lazy to update it)

however, oncalc, it looks shit
the lcd is all blurry, and you can hardly see whats going on Mad

annybody knows solutions for this problem? lower contrast? 8 pixel scrolling...?

Did you used any gray library? And what exactly?

Also halt's don't seem good idea to me. Grayscale is made during interrupts in the libs I have seen and halting seem a problem to me.

Replace halt's to nop's, inc then dec, other wastes of time... You can make a loop of nop's.

the screen shots look grey on my screen. But that is because the image is small and a chess grid looks gray... :S

well, thats what i did, it runs at 25-30 fps now (which is faster than the original floppy version Rolling Eyes )

something i should have done before... every 8 frames i check the 60*22 (why the hell did they chose that size?) array for falling blocks... wich takes a HELL lot of time

in fact, whiteout those halts (which do not trigger on the "psychics" frame) the scrolling isn't exactly "smooth"... :sick:

Well if in a 84+ it slows down a bit in more calculations intense parts, then in a 83 will be much worse. You really want to test in a 83+...
EDIT: or deaccelerate your 84+ (temporarily)

There is a b_call or you can check ports. There is a port that has kind of flags to each model of calculator you are in. Try WikiTI.

Is your choice but if all the stuff to maintain compatible with both models makes the games substantially bigger, I would make 2 versions...
