Need Help FAST!

I have been trying to make a competition cartridge for Invader X. All I need to do is keep the game from awarding extra lives. Maybe change the starting lives from 3 to 2. Problem is I can't seem to get it to work.

 

Can someone please help with this? It is for the Video Game Summit show so it has to be finished today or tomorrow at the very latest.

 

 

Invader X BIN:

Invader_X_cart_NEW_a2.bin

 

Assembly:

Invader_X.zip

To change the starting (extra lives) from 3 to 2.

 

Look for label L144A: - change the 03 to 02 - Lives are stored in the $F2 and $F3 locations (each player)

 

L144A:
   STX	$F6					;3
   STY	$F5					;3
   STY	$ED					;3
   LDA	#$02				   ;2  lives each player
   STA	$F2					;3
   STA	$F3					;3

 

For the not awarding extra lives.

 

Look for label L1609: - change the compare with max lives from 6 to 0

 

L1609:
   LDA	$BA					;3
   BNE	L1619				  ;2
   LDA	$F2,X				  ;4
   CMP	#$00				   ;2   max lives
   BCS	L1619				 ;2

Thanks for the info. I have made the changes but I can't get it to convert to a BIN file. Can someone convert it to a BIN and post it?
