Q1. Are you implementing the game just like the original (i.e. vector
drawing)?
A. No, this is just a quick hack using sprites.
A1. No, this is just a quick hack using sprites.
While it would be pretty amazing, I haven't written
a 6502 optimized vector drawing library.

Q3. Why aren't the keyboard controls the same as the original game?
A. The Apple II has simplistic keyboard support.
A3. The Apple II has simplistic keyboard support.
In general it's not possible to read more than one key at a time.
Also on pre-IIe machines it's not really possible to get key-release events.

A4. It should not be hard to add, and in fact would give controls much
closer to the original.
I probably won't have time to implement it any time soon though.

Q5. Is there anything impressive going on here, like with your other demos?
A. No, it's pretty much straight up "sprite" drawing.
A5. No, it's pretty much straight up "sprite" drawing.
One unusual thing is I am using grey2 (color 10) as the transparent
color rather than black, as there is black in the sprites.

Q6. Why are some cutscenes tiny and some large?
Q. How are you making the graphics?
A6. I started making the cutscenes before I had a good feel for
how large they'd be or how quickly they could run. Some of the
earlier ones are smaller for that reason, before I decided I
could afford full-screen ones.

is roughly 320x200 which scales well).

A8. Yes, but I like it anyway. So many colors!
I spent a lot of time as an ANSI artist so I am used to blocky
16-color graphics, and to be honest with you my art skills sort
of peak at that resolution.

A9. No, there's an official version for the Apple IIgs if you want something
like that. Apple II hires graphics with sprites are a huge pain
to program, would probably be slower, and would take up a lot more
RAM.

A13. Yes, in theory. You would have needed a 48k model which would
have been expensive at the time ($2638). Also the disk image
will fail to auto-boot and HELLO won't run as it's in Applesoft
BASIC (not the Integer BASIC that came with the original II).
