Could someone do an unlimited lives hack for the game Go Fish? Thanks.

I tried to make you one (NTSC), but it didn't turn out perfect.

In bank 0, I changed part of the end routine for a 1 player game as follows.

F722: LDX #$04
F724: JSR $FFF2
F727: JMP $F03A

Doing this makes it so when you hit a bigger fish, you return to the bottom like in a 2 player game. It looks good in Stella, but not when I played it on an Atari using my Harmony cartridge. My changes messed up the timing and the screen jumps whenever you die. I don't know enough about Atari programming to fix it.

In bank 1, I changed the part that adds a point to your opponents score when you hit a big fish.

F34A: ADC #$00   ; This was ADC #$10 and added 1 point for player 1.

F368: NOP        ; This was INC $84 and added 1 point for player 2.
F369: NOP        ; This change reduced the cycle count from 5 to 4.

Maybe this will work for you until someone with more knowledge can make a hack with correct timing.

NOTE: I uploaded the wrong file.... Working on changing it.

I can't figure out how to delete the old file, but here is the corrected one.

Why would you want unlimited lives on Go Fish? It is one of the best homebrews. How many fun video games are relaxing? One life is more than enough.

Thanks dwane413. Works good on my Harmony cart. Only problem is at high volumes there is a background tone but its barely noticeable at a normal volume. I don't see the timing issue. Great for practice at the higher levels.

Glad you like my hack. I made a video where you can see that the screen rolls whenever you die. At least it does for me.
