-
- - Invaders would stop shooting on the higher levels - FIXED.
-
- - I discovered this one during a paricularily good game at school during
- class [snicker].
-
- A number is picked at random, and if it is 2, one of the invaders is
- selected to fire. The number picked is the shot frequency, which is
- decreased every level. Eventually, it reaches 2, which is the maximum
- frequency (the random number 2 shows up every time, and the invaders
- fire constantly).
-
- Unfortunately, the number gets decreased below this value to 0, selecting
- a random number between 0 and 0, thus 2 never shows up, and the invaders
- stop shooting. It was a simple fix.
-
- - Time reset to midnight during game play - FIXED.
-
- - I can't believe I didn't notice this! Dumb dumb dumb!
- Thanks to Patrick A Springman for mentioning this one to me.
-
- The game uses the real time clock for simple timing of the title
- screen delays, printing delays, etc. When the game uses this timer,
- it reset the timer to 0, then watched it until it reached a particular
- value. The problem is, resetting this timer to 0 also resets the clock
- to midnight.
-
- The time change wasn't a permanent change. Once the machine was rebooted,
- the timer is reinitialized with the CMOS clock value, and everything
- returns to normal, but it was annoying anyway.
-
- The game no longer adjusts the timer, rather it reads the current time
- into a variable, adds the delay value to that variable, then watches
- the timer until it reaches this calculated time.
-
- It's better, but does cause some time inconsistancies. Mostly with the
- amount of delay the title screens are displayed for - It doesn't seems to
- affect the game play timing (as expected).
-
- - Added high score functions, and rearranged title screens so score is always
- visible.
