Final Requests for Help

I figured it out. All of her notes were written for a header, but the IPS patch was for a no header rom. 


The other complication is that half of her beta patch was for the purpose of making Steal always hit... obviously not something we want. I was able to remove those portions, and was left with this:

Code:

C2/39E0: EA        NOP
C2/69E1: 20 F0 66    JSR $66F0
C2/69E4: EA
...
C2/39FA: 7A        PLY
C2/39FB: EA EA        NOP

FREESPACE C2
C2/66F0: B9 08 33    LDA $3308,Y
C2/66F3: C9 FF        CMP #$FF
C2/66F5: D0 04        BNE $66FB
C2/66F7: C8        INY
C2/66F8: B9 08 33    LDA $3308,Y
C2/66FB: 60        RTS

What it appears to be doing is this: the first time you steal from an enemy, you will always get their rare steal (seems odd). Then, when you steal again and get a hit, it will increase Y so you're targeting the common steal slot. Only after you have stolen both items will you get the "nothing to steal" message. I'm going to have to chew on this. I feel like the code is 70% of the way there, but not quite finished.

EDIT: Okay, I need help with this. This is the subroutine that decides what to steal. I'm trying to add the following points of logic. As I have it written below, it is working. However, the problem is that if you've already stolen the common item, then the rare item gets a major boost in probability. Here is the logic I want to add in:
1. 1/8th of the time, branch to the rare steal on the first hit (done and working)
2. If you have already stolen the common item, then miss 7/8 of the time. 

In the original C2 routine, there are several branches to C2/3A01, which displays the "can't steal" message. I tried switching this subroutine from a JSR to a JMP so that I could jump out of it to 3A01, but it's crashing the game. Any ideas on what I could add here so that even if you've already stolen the common item, you'll still miss on the rare item 87.5% of the time?

Code:

20 5A 4B    JSR $4B5A    Choose a random number
C9 20        CMP #$20
90 ??        BCC +?? bytes    1 in 8 times, branch to the rare steal (the DEY line)
B9 09 33    LDA $3309,Y     load the common steal
C9 FF        CMP #$FF    Was it already empty?
D0 04        BNE $66FB       If not, branch to the end
[NEED TO ADD SOMETHING HERE]
88        DEY        
B9 09 33    LDA $3309,Y    target the rare steal
60        RTS
