Research: [Pokemon Gold] Day Timer Not Loading on Pokemon Stadium 2

[Airikita]

If anyone is familiar with asm, I checked into the code that loads the time for the game in BGB, and I found the command RST 08 is what is loading data from save data to load the time at address D1DC as stated here: https://datacrystal.romhacking.net/wiki/Pokémon_Gold:RAM_map#Game_Settings

However, it does not seem to work in Pokemon Stadium 2, it always loads the game at Saturday 8:00 AM no matter what...

Considering I made special Pokemon catch-able at night in the game, this is especially frustrating.

I am wondering if this is a result of ASM hacking, if Pokemon Stadium 2 is just known to mess this up, or, perhaps, it is a result of the flash cart I am using for my hacked ROM that I customized (GB USB smart card 64M)?

Command RST 08 actually calls an asm routine from address 00:0008 (= at the beginning of the rom at offset $8).
There we have a jump command to address 00:2E27 where we have a routine that actually calls another asm routine at address defined by a (rom bank) and hl (pointer).

Anyway, where is this routine you were looking at? And what are the values of a and hl when rst 08 is executed? Because in this case, I believe the routine you should be looking at starts at a:hl.
