Retroarch: 32-bit RetroArch is downloading 64-bit cores (libs)

[EmilyLove26]

Description

When I updated to 1.6.0, from 1.5.0, none of my cores work anymore, even after deleting the core folder and redownloading each core.

Expected behavior

Game should launch with the presaved core.

Actual behavior

It says "Failed to open libretro core" and my debug log says

RetroArch [ERROR] :: Failed to open libretro core: "D:\OneDrive\PortableApps\RetroArchPortable\App\RetroArch\cores\gambatte_libretro.dll"
RetroArch [ERROR] :: Error(s): %1 is not a valid Win32 application.

Steps to reproduce the bug

Not sure.

Bisect Results

This started happening after updating from 1.5.0 to 1.6.0.

Are you trying to run 32-bit libs with a 64-bit RetroArch?

Also, the '%1 is not a valid Win32 application' seems weird. Are you launching from a launcher/script?

[EmilyLove26]

Sorry for the late response. I am using a Launcher, specifically one made for PortableApps.com. Even if I don't use the launcher, I still have this issue, even on a clean install.

[hizzlekizzle]

so, what about the 32-bit vs 64-bit thing? Are you sure you're using libs that match the bitness of the executable?

[EmilyLove26]

I narrowed it down a bit. @hizzlekizzle you are correct. However, even if I run a 32-bit RetroArch and have it download the latest libs, it still won't load them. I have to use 64-bit libs. What is going on here? Why am I unable to download 32-bit libs?

[EmilyLove26]

Good timing hahaha. I was just replying.

[hizzlekizzle]

If you're having to use 32-bit libs it means you're using a 32-bit RetroArch build. It will only work with libs that are compiled for the same architecture as the executable.

[EmilyLove26]

Let me clarify. I want to use 32-bit RetroArch, but 32-bit RetroArch keeps downloading 64-bit libs. What can I do to fix this?

[hizzlekizzle]

I just had someone check and they weren't able to reproduce. Can you try moving your config to another place (that is, so RetroArch creates a new one) and see if the problem persists?

[EmilyLove26]

Alright I will

[EmilyLove26]

Weird its working now. I extracted to a new directory.

[EmilyLove26]

I've figured it out. Since I was sharing the config file for both versions in my launcher, it was not able to handle the core_updater_buildbot_url properly. I have fixed this issue.
