Re: [stella] Rally-X as my first game

[Darrell Spice <dspice@xxxxxxxxxxxxxx>]

I started working on it 9 months ago, but picked up a side job soon 
after and haven't pursued it since.  The side job should wrap up in 
another few months, but if you'd like to do Rally X, go ahead as I 
haven't written any Atari code yet.  All I got done was found the map 
for the arcade level 1, wrote a short QBASIC map tool and made some 
notes.

In case you find it useful, I've included a GIF of the map of level 1 
from the arcade, as well as my map conversion tool and it's output.  
The map from the tool is output twice, once in the normal view and once 
rotated.  I was going to experiment with the rotated map to see if it 
would help make the map scroll routine faster(at the expense of 
memory).

Notes:
Player 0 - car
Missile 0 - flags & rocks.  To eliminate flicker, don't allow 
flags/rocks to exist on the same row

Player 1 - enemy car
Missile 1 - enemy car - there can be up to 8 enemy cars so I planned to 
dividing them up between player and missile to reduce flicker.  The odd 
number cars would be Player 1, even number cars would be missile 1.

Ball - smoke screen

radar screen - flicker between 2 colors, 1st screen update showing the 
flags in one color, 2nd screen update showing the enemy cars in another 
color.  Show the player's car position on *both* updates - this way the 
player's car will appear to be a 3rd color.

For the enemy car I was going to do a "hover craft" so that I wouldn't 
have to draw wheels(hard to do when using missiles).

8 game variations

Rally X
1) Normal - start on wave 1
2) Medium - start on wave 4
3) Expert - start on wave 7
4) Child's - start on wave 1, but with just 1 enemy car.  Still 
increase car count by 1 each round(wave 2 would have 2 enemy cars)

New Rally X- adds lucky flag which does not show on radar and gives a 
bonus based on fuel remaining when found
5) Normal - start on wave 1
6) Medium - start on wave 4
7) Expert - start on wave 7
8) Child's - start on wave 1, w/1 enemy car
