No longer a proof of concept. The game checks if the value isn't correct, so it would be overwritten. This just freezes the value using some code cave code nearby the fence skip thing.

# How to find the memory address where the weather is stored (if it needs to be updated):
|
|
# 1. Make 1 breakpoint on one of the following instructions using Cemu's PPC debugger:
|
|
# .text:03668FE8 stb r0, 0x19(r30)
|
|
# .text:03668FEC stb r26, 0x18(r30)
|
|
# 2. Fast travel into an area where the weather isn't constant
|
|
# 3. After it hits the breakpoint, look at the register view and find the value after R30.
|
|
# 4. Use a hex calculator to add 0x18 to that address and you'll have the address. |
