Hack Request - Enable Def Control By Default

[Mhopkinsinc]

User story

Majority of SNES players turn on Def Control during game play. Would like to Enable Def Control by default without having to turn it on in the Pause Menu.

Possible Solution

• [x] ASM injection, jump to new area of code the sets the Def. Control ON for both Home and Away teams.
• [x] Mesen Trace File [Not needed, solution is already known]

Actual Solution

• ASM injection at [9F837C] - Perform JSR to new code @ [9F83DE] in bank 9F
• Call existing JSL we hijacked and then run code to set 1C94 & 1C96 = 1
• These are the Def. Control variables for home and away teams.

Acceptance criteria

• [x] Pause Menu - Def. Control is On when before starting the game
• [x] Pause Menu - Can still turn off Def. Control via the menu option
• [x] Game Play - L & R trigger on joypad controls left and right defense as expected
• [x] Updated SNES NHL94 ROM-RAM Mapping Project with any new values.

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.

[2] New code to turn on Defense Control for Home and Away teams.

[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.
