Title: Runahead-enabled emulators for XP
Post by: ncflagg on January 30, 2021, 06:05:49 pm

I want try running some arcade games on my Windows XP cab with the runahead frames feature (Street Fighter II as well as older games). Do you know of any 32-bit runahead-enabled emulators?

Retroarch has cores which can do this (Mame2003-plus), and in a 32-bit package but it just says "The system cannot execute the specified program" when I try to run it and also oddly is not logging anything in event viewer.

I got Retroarch 1.9.0 working with runahead. The piece I was missing was the x86 windows-msvc2010 build. I was trying to get the "RetroArch-x86-setup.exe" working in XP. It appears that build works in Windows 7 32-bit, but not XP since it links to libraries XP does not have.

From all the other threads I looked through yesterday, no one mentioned msvc2010 was the proper build for XP. That may mean the msvc2003 is the build some were saying is for Win98, etc.

Retroarch Windows XP build: http://buildbot.libretro.com/stable/1.9.0/windows-msvc2010/x86/RetroArch-msvc2010-x86-setup.exe (http://buildbot.libretro.com/stable/1.9.0/windows-msvc2010/x86/RetroArch-msvc2010-x86-setup.exe)
Visual C++ 2010 Redistributable is required: https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0 (https://support.microsoft.com/en-us/topic/the-latest-supported-visual-c-downloads-2647da03-1eea-4433-9aff-95f26a218cc0)
..as is a manifest file inside the folder with retroarch.exe: https://gist.github.com/cetinajero/98f22d646698cd1ef74e896d8f7f7a9c (https://gist.github.com/cetinajero/98f22d646698cd1ef74e896d8f7f7a9c)
You may also need to change video_driver inside the retroarch.cfg if it still won't load.
