Hi there,
I'm not the developer, so some of this is guess work.
It looks like the Galaxy Go is a "Windows on ARM" laptop, so it's processor is more like a beefed up version of what you'd find in a smartphone or Android tablet, than what you'd expect from a regular Window machine.
Window on ARM runs regular Windows software through an emulation layer, but the emulation isn't perfect Windows 10 only support 32bit software, and while Windows 11 has added support for 64bit software, games support is overall is pretty rough.
I think (and this is the guess work) that Bloodborne PSX is a 64bit program, because a lot of the program files say "win64" in their names.
Hope this is helpful.
