Do you perhaps mean Bochs[1]? I've seen it booting Windows 95 on an early PSP and similar stunts, so running Windows inside Bochs on a smartphone would IMO not be that much out of the ordinary.
Or is there really a PC emulator from BOSCH[2] available somewhere?
I just found the idea quite funny that I could have a "BOSCH emulator" in my tool box, right next to my BOSCH electric drill. Especially since OP even used the capitalized spelling from the brand logo.
I'm not trying to be mean here, I genuinely found it funny and tried to point that out the way people usually do in social interactions, rather than rudely responding along the lines of "OMG you made a typo there". I guess that got a little "lost in translation" due to the textual medium and culture difference?
