About desperation moves...

Thanks,

After spending a lot of time studying(or trying ) the code of desperation and target in general, i made up a try...

C2/295A 20 69 64 (jump to 026669, headered)
EA EA EA EA (nothing x 4, for replace 7 bytes)


C2/6669 F0 07 (branch if equal, skip 7 bytes) (related to the original code above the first line, so nothing strange)

A5 B6 (LDA selected spell, the desperate)

C9 F0 (CMP F0, > 0 if B6 >= F0)
B0 01 (BCS 01, if CMP above is >= 0, skip 1 byte)

60 (RTS, all checks failed, so nothing happens)

AD A0 11 (LDA spell aiming byte)
85 BB (STA to targeting byte)
60 (RTS, the first check that work triggers LDA, STA)

I was quite confident on the result... nothing changes
Still better than a crash or crappy stuff, i guess...

What do you think about the code?
Could it had a chance of working, or i'm on completely the wrong track?
