64-bit game: How to jump near allocated memory when there is long jump?
Posted: Sat Aug 21, 2021 6:22 am
in this 64 bit game, Final Fantasy XV, i'm trying to make infinite health and one hit kills, but when i activate the script it does a long jump (use larger allocated memory) which means my game could likely crash while enabling/disabling the script. I'll show what I mean with an image:
I thought it looked weird. Look at the bytes where I inject, isn't that too big?
Is there a way to tell the script to jump 'near' or jump 'short' in allocated memory? How can I do it? I will post my script, if you have suggestion to add to my code to fix this large jump issue, please specify where I need to put the code you're telling me to edit. Thanks. Also if you have a better/more efficient method to fix this issue, please elaborate, i'm trying to learn after all.
Here's a snapshot of the instructions nearby:
ended up getting some help from DB. told me to put a far jump at newmem. however it's still crashing, don't know the issue. any help?
edit: found the issue. the jumps near my injection point were interfering with injection. had to pick a different injection point. and also learned out how to do the long jumps properly thanks to dark byte and some other good folks from cheat the game discord.
