Q. Why aren't the keyboard controls the same as the original game?
|
||||
|
||||
A. The Apple II has simplistic keyboard support.
|
||||
In general it's not possible to read more than one key at a time.
|
||||
Additionally, on older models there's no auto-repeat unless you
|
||||
hold down the REPT key, which makes running difficult.
|
||||
The original game really depends on being able to detect having
|
||||
multiple keys down at once.

Q. Does this have joystick support?
|

|

A. It should not be hard to add, and in fact would give better controls

than the keyboard. I don't currently have a joystick though so

it's hard to test properly.

Q. Why are you targeting such an old machine, an original Apple II or II+?

from 1977, whose graphics hardware is a glorified shift register,

@ -74,13 +101,10 @@ A. The Apple II/II+ only supported uppercase letters by default.

Also no "|" character, which explains why some of the ASCII art

looks a bit odd.
|

I suppose I could auto-uppercase on older machines on the fly like

my Still Alive demo does. The memory budget is a bit tight though.
