Real Time Clock [SNES] Note: Full credit to @Brodeur30 & @kingraph for the original GENS hack. Problem: Request for the Real Time Clock feature to be implemented on the SNES. This enables period and penalty durations to correspond with actual real-world time, meaning a 5-minute period is equivalent to 5 real minutes. Modify The Time Clock To Be Real Time: Want to make the time clock use real time instead of 2.5x speed? ROM Offset: (hex)F85B6-F85B7 Change: AA 0A to 44 04 The above change will slow the clock down to real time. Modify The Penalty Clock To Be Real Time: Want to make the penalty clock real time? ROM Offset: (hex)F3F66-F3F67 Change: 18 00 to 3C 00 ROM Offset: (hex)F8668-F8669 Change: 18 00 to 3C 00 The above 2 changes will make the penalty clock real time. BONUS INFO: This is all setup already on the SNES GitHub repo along with other Hacks. Check it out!

Pull CPU Goalie earlier when losing [SNES] Problem: Would like the CPU to pull its goalie earlier in the 3rd period when losing by 1 or more goals. Pull CPU Goalie earlier in the 3rd: Want to change how early the CPU pulls its goalie when losing? ROM Offset: (hex)00F5150-00F5151 Change: 3D 00 to 96 00 The above change will pull the goalie with 2:30 remaining in the 3rd period. Pull CPU Goalie when losing by more than 2 goals: You can also modify how many goals the CPU is losing by when the goalie gets pulled. ROM Offset: (hex)000F5148 Change: 03 to 04 The above change will pull the goalie when losing by 1, 2 or 3 goals. BONUS INFO: This is all setup already on the SNES GitHub repo along with other Hacks. Check it out!

Pull CPU Goalie earlier when losing Note: Thanks to @chaos & @smozoma for assisting with some 68K assembly knowledge sharing. Pull CPU Goalie earlier in the 3rd: Want to change how early the CPU pulls its goalie when losing? ROM Offset: (hex)0000F766-0000F767 Change: 00 3C to 00 96 The above change will pull the goalie with 2:30 remaining in the 3rd period. Pull CPU Goalie when losing by 1 goal instead of 2: You can also modify how many goals the CPU is losing by when the goalie gets pulled. **There is currently a bug in GENS where it will only pull the goalie if its equal to this value. See below patch by @smozoma to fix this. ROM Offset: (hex)0000F75F Change: 02 to 01 The above change will pull the goalie when losing by 1 goal instead of 2 goals.

Turn On Defense Control By Default Note: Full credit to @smozoma for the original hack. This post details the process of incorporating it into the disassembled ROM, allowing it to be recompiled into the game with configurable options. Tutorials to follow in the future on how you can recompile the rom yourself. Problem: Defense Control is turned off as a default setting in the game, but the majority of SNES players favor having it enabled from the start. Solution: The same as the original hack, we have to swap out some of the existing code and insert a jump to new code we create. This new code will be placed in the free space at the end of the 9F bank. [1] Hijack old code and have it jump to the new code we add at the bottom of the bank. Line 322 [2] New code to turn on Defense Control for Home and Away teams. Line 11391 [3] I've introduced a variable named !Defense_Control, which you have the option to enable or disable during the compilation of your ROM. The intention is to add more configurable variables for ROM building in the future. Currently, there are two additional variables available: one to adjust penalty duration and another to activate the hidden 30-second periods. BONUS INFO: The code we initially diverted from was actually responsible for determining the starting goalie in the game. This opens up potential for further modifications, such as automatically starting the 2nd goalie, or even enabling on-the-fly pulling of the goalie without needing to pause the game. nhl94.sfc

Enable 1 Minute Penalties Problem: The SNES rom crashes when you try to modify penalties to be 1 minute, as the game developers never expected there to be 1 minute penalties. Solution: Modify the penalty length in the ROM and skip the problematic check for 0 or 1 if the penalty length is one minute. Technical Details: Similar to the "Defense Ctrl" code injection method, we have to swap out some of the existing code and insert a jump to new code that we create. This new code will be placed in the free space at the end of the 9E bank. Problem Code: Hijack Instruction before the problem code and run new code (One_Min_Pen) Run new code to skip the compare if we know its a one minute penalty and continue like normal as if it was a 2 min penalty. I have included the 1 min penalty rom to play around with or compare for differences if interested. Or you can download the tool and create your own ROM. https://github.com/Mhopkinsinc/NHL94SNESVault/releases nhl94.sfc Hex Version: 1) Change all the penalties from 02 minutes to 01 minutes. Headerless ROM (.SFC) ROM Offsets: (hex) 54C7,54E9,550B,552B,554B,556B,558C,55B1,55C9 Change:02 to 01 Headered ROM (.SMC) ROM Offsets: (hex) 56C7,56E9,570B,572B,574B,576B,578C,57B1,57C9 Change:02 to 01 2) Hijack old code and point to the new code Headerless ROM (.SFC) ROM Offsets: (hex) F3417-F3419 Change:29 FF 00 to 4C 5B FB Headered ROM (.SMC) ROM Offsets: (hex) F3617-F3619 Change:29 FF 00 to 4C 5B FB 3) Insert new code that fixes the bug Headerless ROM (.SFC) ROM Offsets: (hex) F7B5B-F7B6D Change: FF's to C9 01 04 F0 05 C9 01 0A D0 03 4C 21 B4 29 FF 00 4C 1A B4 Headered ROM (.SMC) ROM Offsets: (hex) F7D5B-F7D6D Change: FF's to C9 01 04 F0 05 C9 01 0A D0 03 4C 21 B4 29 FF 00 4C 1A B4

Enable Hidden "30 Second" Periods I think this hack was originally found in the GENS version but may not have been fully documented. Here is the link to my GENS post, its slightly different. Guess what? Buried deep in the ROM, like a pirate's treasure, there's a sneaky '30 Second' period option playing hide-and-seek! If you're up for a bit of digital treasure hunting and want to unlock this secret in your ROM, just tweak these Hex values Headerless Rom ROM Offset: (hex) 000EACD7 Change: 03 to 04 It's like whispering a secret code to open a hidden chamber! But beware, once you activate it, your game time could disappear faster than a fart in the wind – one minute you're playing, the next, poof! It's all over! nhl94.sfc

NHL 94 SNES This post contains information about the SNES version of NHL 94'. Similar to the thread created on the GENS side, I thought I would try and get this going on the SNES side as well.

This looks phenomenal, can't wait to try it.

In, Que please.

I'm in.

Hey UltraMagnus, You found the locations for the Snes rom or Gens rom?

~

I'm in.

@McMarkis - Can you add me to the wait list. Would love to try this out.

I can confirm, I had the same problem. You need to use the ROM that is NOT headerless. https://nhl94.com/multimedia/apps/nhl94_snes_smc.rar

@McMarkis

In, A league please.

In, B league.

I'm In.

Sounds good

Sorry for the tardiness, I can play tonight if your available?

I believe a few of us have let you know that bigfoots internet connection is not really suitable for play. His ping is over 100ms and he has to change the screen refresh setting in kaillera client to +7

C4, I can play tonight.
