I know this thread is for pokemon gold but i think this is useful:

Actually there is a clockreset method in the titlescreen of pokemon crystal ... but it is much harder to get there as it was in gold/silver, here is a short tutorial:

1. Boot up the game to the titlescreen
2. Push and hold Down+B+Select
3. Release Down+B but keep Select hold down
4. Press Left+Up (still holding Select down)
5. Release the Select button

Now the password reset dialog should pop up ...

But I think this is far too complicated for daily use.
So here is a patch that allows you to reset the clock everytime you load a savegame of pokemon crystal for any version (language/region does not matter) :)
Pokemon Crystal RTC Patch

This patch does not seem to work correctly on VBA, but who cares if it's working well on the everdrive? ^^
I'm here just to say THANK YOU!!!
Was looking for this file and you saved me.
Now i can play Pokemon Crystal Restored(A hack that restores Crystal Japanese version exclusive content) on my real Game Boy Advance 101.

Can someone rehost the IPS file? The link no longer works.

Done, here ya go.

Reading the subroutine for the "clock reset" menu, all it did was write 0x80 to a byte of the save RAM. It's a "clock reset byte", I guess. So I put a read breakpoint there, and I find a function which reads the byte as a return value. So I hard-code the return value of that function to be 0x80 instead of whatever the value actually is. It seems to do the trick.
 
Hello,

sorry for the necro.
A few years back I used @cosmo-freak 's patch in order to play the game while using the first EDGB & clones.
I learnt that GB roms had a second checksum (not the header one) which is more in line with most other consoles do (i.e. checksum of entire rom content).
Obviously applying a patch breaks verification - not an issue on a console since the BIOS never does a comparison... but if you have such a ROM flashed to a cart + Transfer Pak - Pokemon Stadium 2's GB tower will throw an error.
Here's a zip file containing XDELTA ver 3 patches for EUR/USA GSC games. It's a simple combination of the original IPS patches + corrected checksum.
Tested every variation with EDGB + saturnu's ED64/TP stuff and they all load fine.
