Add additional stats in SRAM

Recommended Posts

This is a quick and dirty method for tracking fumbles...I could probably move it to work on a 32 team rom but for now its just good for 28 team rom league play.

 

 

 

 

 

 

 

SET( 0x286EA,0x4C00E5EA)

 

 

SET( 0x2ADEC,0x4C1EE5)

 

 

SET(0x3E510,0xA9808D01A024707006EEA07F4C12E5EEA27FA9C08D01A0A001B1AE4CDE86A9808D01A0A5702940482078B06845702940F00D24705006EEA17F4C3FE5EEA37FA9C08D01A04CDFAD)

this is an awesome idea.  i love more stats to display on a box score.  fumbles lost can reveal what happened when the stats seem to indicate a different result.  however, everytime i run a com v com game with this hack the fumble can never be picked up.  with the exception of 1 time where the qb picked the ball back up and threw it again (pretty awesome if you ask me), but then the ball went past the endzone and laid in the stands forever.  the refs never reset the play.

I just double checked using this on the tsb original rom and it worked fine.

 

 

And also tested this on the HSRL rom and it worked fine. Maybe you pasted it wrong or its on a rom with some other hack. 

 

could be either.  i'll double check and try again.  i was using the 2.0 rom which has a number of other hacks on it.

 

EDIT: yep, just a transcription error on my part.  all looks good!

Brooks, would it be a (fairly) simple fix to the phile to allow the ability to track fumbles?  Lots of discussion on the HSRL boards about fumbles and the ability to add to the phile came up recently.

This hack uses season SRAM so it won't work for season games. 

 

Stats are stored at the following locations. I forget what this gets converted to for nestopia

 

These are stored as decimal numbers and not hex numbers

 

P1 MIN = $67B0 , SAVE STATE: $1A3F

P1 SEC =$67B1, SAVE STATE: $1A40

 

P2 SEC =$67B2, SAVE STATE: $1A41

P2 SEC =$67B3, SAVE STATE: $1A42

 

  

 

TIME OF POSSESION HACK SOURCE

 

SET (0x22309, 0x4C00E0EA)
