how to edit power play and home-ice advantages, GENS and SNES


Recommended Posts

If you open an NHL94 rom in NOSE, at the bottom-lefthand corner of the screen you will notice six hex bytes. They are assigned by team.

The example is San Jose from the new 2009 Update Rom.

The first byte ("45") is still unknown. GDL and Capitalism (now) has it set at "44" for all teams.

The second and third bytes ("11" and "11") are PP/PK advantages and home/away advantages, respectively. GDL has is set at "11 10," Capitalism has it set at "00 00."

Byte 1's actual digits usually add up to less than 10, IIRC.

Byte 2 and 3 does not have digits higher than 3, and in most cases no higher than 2.

The fourth byte ("F9") is the number of forwards, followed by the number of defensemen on the team.

The fifth and sixth bytes ("C6 00") are the bytes assigned to the team's goalies.

These bytes sit somewhere in the range of 66-72 bytes BEFORE the first player on that given team.

You must find them in a hex editor to change the first three values. However, by some minor checking, you will be able to identify the bytes very quickly based on their proximity to the first player and their actual values.

This is the basically the same in SNES as it is in GENS.

The first 6 numbers:

Offense - Good 7 ... 0 Bad
Defense - Good 0 ... 7 Bad
PP	  - Good 2 ... 0 Bad
PK	  - Good 0 ... 2 Bad
Home	- Good 2 ... 0 Bad
Away	- Good 0 ... 2 Bad (3 Really bad (OTT, FLA, ANH))

Just a note...

I have verified that the game actually does use the home/away values.

It appears that it uses the values as parameters in the AI code for each player (this is just a guess based on the fact that it reads the value 10 times.. twice for each player on your team)

Home Ice Advantage can be from 0-5.

If you want no Home Ice Advantage You can get it by setting all teams Home Setting to zero/weak and Away Setting to zero/strong.

0+0=0 no home ice advantage.

Detroit does not really play better on the road this is fake news or misinformation.
when Detroit plays at Montreal, the Canadiens have a +2 Home Ice Advantage.
MTL Home two/strong and DET Away zero/strong

2+0=2 Home Ice Advantage

Philly at LA looks like this.
LA Home one/average and PHI Away two/weak

1+2=3 Home Ice Advantage

Anaheim at Pittsburgh looks like this
PIT Home two/strong and ANA three/brutal

2+3=5 Home Ice Advantage

To resurrect this, does anyone know where I can find this stuff in the actual hex code? Can't run NOSE or EARE on my mac.

The home/away/pp/pk advantages will be in the team data for each team.  It's right before the player data starts...1 byte is Off/Def, 1 byte is PP/PK, and 1 byte is H/A.
