Unicorn-Engine error of type 19 (EIP: 0x00424358)

adolfintel commented 6 years ago

I tried building OpenSWE1R using the build instructions on the wiki but I'm getting an error when running.

The steps I followed:

Installed MSYS2
Opened MSYS2 - MinGW64
pacman -Syu
Installed git, cmake, gcc, make, python2, etc. (I had to do this "interactively" since the wiki doesn't have a clear list of the packages needed to build it)
Built Unicorn engine and installed the package
Cloned openswe1r repository (commit ef8ca30b831a4cc967b3fd927a1aaf559c490c38)
Built openswe1r
Copied openswe1r.exe and the required DLLs to the game's folder
Ran openswe1r.exe, a white window briefly popped up before the error appeared (compatibility flags and permissions had no effect)

System configuration:

Windows 10 x64 1803
i7 8700k (virtualization enabled)
GTX 1080 (no issues with OpenGL driver)

Game version:

GOG (hotfix2)
Also tested the original game with the official patch (same result)

Files

Log

I tried looking up the error but I can't find anything.

I can reproduce the issue on Linux (USE_VM enabled) running PR #150 (Although EIP: 0x0042437F, maybe #102 ). Without USE_VM I also get Unicorn-Engine error of type 19 at 0x0, size = 0x4 (EIP: 0x00424358)

I'll run the "hotfix" and "hotfix2" through a diff and document what I see. Keep an eye on #142

Is this specific of hotfix2? Because I have the original game files too and I'm getting the same error there (unless the install is somehow corrupt)

JayFoxRox commented 6 years ago

I've tried (each with #150 ):

gog.com 1.0: working
gog.com 1.0 hotfix: working
gog.com 1.0 hotfix2: broken, same error as described in issue title

Are you sure it's the same error when using another version of the game? In addition to this current issue, version ef8ca30 of OpenSWE1R you are using is not compatible with gog.com yet. Please check out #150 which addresses other issues which will arise even after fixing this one.

I guess the crack I'm using has something in common with the hotfix 2 then. It was downloaded a good 18 years ago 😂

adolfintel commented 6 years ago

Shit, confirmed, I tried using the original exe and the game starts

Please check if #153 (in review at this point) resolves this issue for you.
