Vertical scrolling games for the Apple ///

Paul Hagstrom, July 2023

A couple of work in progress games to be described at KFest 2023.

Lazy River

boat on a river

Logdrive

a lot of logs on a river

spyhunter?

parallax?

relics

old stuff that hasn't been cleaned up yet

Compilation

I use ca65 to compile this, and AppleCommander to get it onto a disk image. My steps are:

ca65 a3wheel.s
ld65 -o a3wheel.bin -C apple3big.cfg a3wheel.o
ac -d a3wheel.po SOS.INTERP
ac -p a3wheel.po SOS.INTERP bin < a3wheel.bin

ca65 lazyriver.s
ld65 -o lazyriver.bin -C ../apple3big.cfg lazyriver.o
ac -d lazyriver.po SOS.INTERP 
ac -p lazyriver.po SOS.INTERP bin < lazyriver.bin

I use Applecommander, requires java, but brew install might be sufficient

See https://github.com/lifepillar/homebrew-appleii and https://applecommander.github.io/install/

brew tap lifepillar/appleii
brew install applecommander-ac
alias ac='/opt/homebrew/Cellar/applecommander-ac/1.8.0/bin/ac'

test install with:

ac -h
