I was following this Guide:
https://pokemon-speedrunning.github.io/speedrun-routes/#/gen-1/red-blue/main-any/
I got the timing for the save corrupt right and followed the instructions of swapping the pokemon, the items and the pokemon again. But after I close the Menu, the Screen freezes and a random Check pattern is shown (see screenshot below).
For the setup, I followed this Guide (and it seems to work):

What I did not do is the Manip TID 64C2 (25794) because I did overread it first:
Do I have to perform the Manip TID 64C2 (25794) before the save corrupt? And if so, do I need to do it before every run? Or is the problem something else?
I am very thankfull for any help and I am looking forward to hear from u :)
You must perform the TID manip before every run. The ACE you perform as part of the run depends on your TID being a specific value. If it is not that value, the ACE will not execute properly and will most likely crash the game.
