Crash with Forza Horizon 4 (the original Mr. Goldberg work)

[tealaforgia]

Describe the bug
Using GBE Fork (experimental or regular) with Forza Horizon 4 (applied on my clean steam files), the game only works as long as you stay in the menus or in the garage, but when you go into the game and it renders the city, after a few seconds the game crashes. With the Goldberg_Lan_Steam_Emu_master--475342f0 this does not happen and you can play and the overlay works, but with this fork the overlay doesn't open (even with many other games the overlay only works with the original emulator, but that's not why I'm here, I've already read that you can't take care of it for now and I understand that). The same problem seems to have been reported in this post on cs.rin.ru.

Emulator version
I tried 2025_07_20_Exp, 2025_07_20_Reg, 2024_08_Exp, 2024_08_Reg, with or without Goldberg XLive offline emulator, with or without overlay enabled in configs.overlay.ini

Debug log
Some personal information has been redacted.

steam_settings file
This is one of the configurations that i used.

Requirement

• I am uploaded debug log.
• I am uploaded steam_setting file.
• I am sure the game not using 3rd party server (Photon, Playfab, GC, etc).
• I am sure can run the game offline.

To Reproduce
Steps to reproduce the behavior:

1. Obtain CSF of Forza Horizon 4
2. Use generate_interfaces_x64.exe with original steam_api64.dll
3. Copy DLL's from Experimental folder
4. Generate steam_settings with generate_emu_config.exe
5. Copy steam_settings in the game folder
6. You can add XLive emulator, change some settings in steam_settings, nothing will change things.

Expected behavior
The game works properly, even online if you don't use the XLive emulator, like with Mr. Goldberg's old emulator.

once I'm home I'll check with my build. I fixed lots of overlay issues and game crashes. Will download Forza Horizon 4 and let you know my results. Thx for sharing.

seems something wrong with your broadcast list

it should be
10.0.0.255
172.0.0.255
// WHY there si 255.255.255.255??

Please DONT use overlay oif possible! I know might seems neccessary but ensure the game runs first THEN test for overlay!

Also is there a crash.log or crash.txt?

SideNote:
I swear i will make a global easy pre-made settings with all values still intact fucking hate when everyone stripping out the .ini files!

Also zero clue why not works

maybe because it expect thit ot return false:
Steam_Remote_Storage::IsCloudEnabledForApp ? (OG Golberg does the same as current with this stuff)

I also tried to disable overlay, if you need it i can run the game with debug release and send log.

What could be causing this? If it helps, this is the ipconfig output (translated from italian):

Realtek 2.5GbE Ethernet adapter:

   Connection-specific DNS suffix: lan
   Link-local IPv6 address . : fe80::b5c8:539e:c749:ebac%15
   IPv4 address . . . . . . . . . . . . : 10.1.3.1
   Subnet mask . . . . . . . . . . . . . : 255.0.0.0
   Default gateway . . . . . . . . . : 10.1.1.1

Also is there a crash.log or crash.txt?

Where can I find them? There are no other logs in the game folder, in %localappdata%\ForzaHorizon4 and in %appdata%\GSE Saves\1293830

The other .ini files are in the %appdata%\GSE Saves\settings folder:

configs.main.ini:

[main::general]
enable_account_avatar=1

[main::connectivity]
listen_port=47584
disable_lan_only=1
disable_networking=0
offline=0

configs.overlay.ini:

[overlay::general]
enable_experimental_overlay=1

[overlay::appearance]
Font_Override=Roboto-Medium.ttf
Font_Size=48.0
Icon_Size=128.0
Achievement_Unlock_Datetime_Format=%d/%m/%Y - %H:%M:%S

With this global configuration, I haven't had any problems in other games. If you want logs with a specific configuration, or with original Goldberg, let me know.

The crash is probably caused by a different behavior than the original emulator, because it works with that. Also, I think it's somewhat relevant that as long as you're in the menus, the game works, and you can even go online and buy cars at auction from other players. The crash occurs 1-2 seconds after the city is rendered.

Test with working GB and latest and send both logs. Without overlay please

Where can I find the debug version of the original emulator? The debug folder is empty in the version downloaded from the official website and GitLab.

Difference between Mr. Goldberg and gbe-fork is that on 2024/4/30 this was added/fixed:

fixed a bug where sanitizing paths in the settings parser would remove the colon ':' character,
preventing the usage of absolute paths on Windows, like: C:\aa\bb

The game tries to open a NerdConfig.ini which the original Mr. Goldberg seem to ignore and the gbe-fork results in a crash. Just my theory. I don't have a fork prior 2024/04/30 release unfortunately. So I need some time to fix/revert that, compile and test it.

[16820] GameConfigRuntime :  onAppStaerted, p1 =  1258 , p2 =  20916
[20916] [S_API] SteamAPI_Init(): Loaded 'C:\Games\Forza Horizon 4 (1293830)\steamclient64.dll' OK.
[20916] [CScriptScopeINI]
[20916] NerdConfig
[20916] : unable to open INI file:

But yeah game is crashing with current build and I guess that's the issue. But take it with a grain of salt ¯\_(ツ)_/¯

Additionally, I noticed that the game work without crash using steamclient loader, and the overlay work too.
