Bug with no solution?! Backpatch error. - Talkashie - 01-01-2016
I recently put some of my gamecube games onto my computer so I could play with higher graphics details, but it doesn't seem to be working right. At random points in SA2B, I will get the following error message and Dolphin will crash:
![[Image: backpatch.png]](http://s28.postimg.org/b64g71oct/backpatch.png)
As many details as I can give:
Game Name: Sonic Adventure 2 Battle
Game ID: GSNE8P
Steps to Reproduce: Seemingly random, I haven't found a reliable way to reproduce it
Dolphin Version: 4.0-8506, 64bit
PC Specs: i5 4690k @ 5GHz / GTX 980 4GB SC / 32GB DDR3 / Windows 7 Ultimate x64
EDIT: I am also getting other error messages, something about StackHash_2895 or something. The errors seem to be different every time
This makes me feel as if my problem will never be solved.Another example of an error that popped up:
Invalid read from 0xfffff8f6, PC = 0x8011d2c0
EDIT2: I set the CPU Emulator Engine to JITIL Recompiler and it has not crashed yet. Crossing my fingers, hoping that this fixes the issue, but I have my doubts...
EDIT3: Of course, this didn't fix the issue like I had hoped. I guess I will just go back to playing my games on the GameCube
ANOTHER ERROR MESSAGE! Geez...
IntCPU: Unknown instruction 01000000 at PC = 00000008 last_pc = 81200c9c LR = 00000000

What is the MD5-Hash of your dump? Rightclick on the game -> Properties -> Info -> Compute
It seems it should be "9ef5fadf4b8756af820df997468a5a16" for your version. If it is not, then it is a bad dump and you should redump it.

I just clicked compute on mine, and it came up as '9ef5fadf4b8756af820df997468a5a16'
EDIT: I think disabling Dual Core Mode fixed the issue. For anyone else having this problem in the future, try this.

I was just playing this game yesterday with a friend and the game kept crashing (I had panic handlers turned off so I didn't see the errors).
When I get some time I'll try and find which build caused these issues to arise.

Turning off Dual Core Mode seemed to fix my crashing. Try that and let me know if it works for you as well!
