Sinclair ZX80 / ZX81 / Z88 Forums

I think I can make a 1K PACMAN with the original screen.

So far coded:
- compressed screen to load in 1K.
- defining own keycontrols
- decompress screen to full size
- start of game
- reset score
- control of pacman

Still 245 bytes free for
- restart
- ghost move
- score (eating)
- hiscore
- levelup
- bonusitems

K-MAN will be part of the new game tape.

Blimey!

Still playing 1k frogger and painter so looking forward to this!
dr beep is the Yoda of 1024 bytes.

To do:

move ghost, status ghost and dead.
114 bytes left for full sixe Pacman.

71 bytes left

to do:
status ghost
timer ghost chaseable
capture test
hiscore

I think I need to cut a few pixels from the full screen.

Yes, I need to take a bit of the screen for the final steps.

At this moment 2 lines deleted.

Only to do:
point for eating ghost and hiscore

No bonusitems

32 bytes left.

Only just restarting my zx81 programming journey after a 40 year break. Doing all this in 1k blows my mind

You can use the $403c to $407a memory block ?

yes, printerbuffer is free to use as is most of the systemvariables. I only avoid
dfile, lastk, frames, margin and cdflag
