I have fixed the playoffs bug in NHL95. You can get a fixed version of the game here.
If you don't know what this is about: There was a game-breaking bug in NHL95 that made it so you missed the playoffs if you got 128 or more points in the regular season. (See some discussion about that in this other thread)
I made a short video covering the fix
The short story of the bug is that the programmer accidentally used some CPU instructions that only work for numbers up to 127. I switched them to use the instructions that work for numbers up to 255.
If you have a season you've already started (but haven't started the playoffs yet), the fix will work for it (you don't need to start a new season)
There are 3 different ways to get the fix here. You just need 1. I recommend getting the fixed ROM.
Option 1 - Download Fixed ROM
Here is the fixed ROM (complete game file). You can play this file in any emulator software, or on original hardware with an EverDrive cartridge:
NHL95-PlayoffsFix.bin
Option 2 - IPS Patch
Here is an IPS patch for if you want to update the ROM yourself:
NHL95-PlayoffsFix.ips
Option 3 - Game Genie Codes
And if you want to use the fix on an original cartridge on an original Sega Genesis, here are the Game Genie codes to use:
MUST DO before beginning playoffs:
ATDA-AA6T - Disable Checksum (if you don't do this one, other codes will cause game to refuse to load)
ADLT-WE7L - Playoffs Fix 1/2
ADLT-WL7R - Playoffs Fix 2/2
OPTIONAL:
AANA-WE4E - Standings Fix 1/2
AANA-WL4J - Standings Fix 2/2
I verified these in an emulator, so I am just assuming they work on real hardware. You only really need to enter the first 3 codes once you finish the regular season, but before selecting the "Move on to playoffs" option. The last 2 codes just fix the standings display, so you would use those ones during the regular season to see yourself at the top of the standings -- but they aren't needed for the playoff seeding.
If I made a mistake in the game genie codes and it doesn't work, I'm sorry. I will test it out when I can. Game Genie is in the mail.
