My game crashes.

[+atari2600land]

I have a problem. In "Oh Well" in my :Going Bananas" game, version 7, when I get around 60 or so fruits falling down (they don't have to be in the same round), the sfx quit working correctly, and then I get a message in Stella saying "Invalid ROM instruction" or something like that and the game crashes. I don't know why. I cleaned up the code a lot, and I know it's probably not going to happen anyway but I just thought I should ask, but I need someone to look through the Oh Well part of the code (lines 664-1738) and find out why? Because I can't figure out why it's doing this. This never happened to me before, having Stella tell me my game crashed.

I just played until 150 points and experienced no crash.

I get this:

I think I fixed it.

 

I think the problem was I had put too many rts in there. I'm guessing the result was it had jumped to code that wasn't ready to be executed yet and so it acted crazy up until it didn't work any more.

I was just about to post.  I looked at it, and your stack was getting bigger and bigger and bigger with $f418 as the return address, and it eventually was overwriting all the RAM.

Hm, what I played looked nothing like this.

It's got two menu options at the start. Gives two different games, by the look of it.

I'm having another small problem: I don't understand the "and" function. I'm needing a number between 1-16. Wouldn't this:

	jsr Random
	and #15
	sta FlyMoveTimerLimit

get FlyMoveTimerLimit a number between 0-15? And yet the fly doesn't seem to want to change its direction very much if at all.

Never mind. I figured it out.
