I then saved this .exe to a disk image, and then saved that disk image back to my modern mac that I'm doing this on via downloading that in the browser.
I then took that .exe and the only dependency - vbrun100.dll - and put it on a floppy (a real one) and then took that floppy over to a vintage computer I have that has Windows 3.1 on it still (an old 25 MHz Intel486 DX industrial computer I have sitting in a closet with no real use for). Popped in the floppy, copied the .exe and .dll.
And ran the program, no problem! A real GUI windows program, made in VB running in Windows 3.1, inside an entire emulated machine in Javascript in a browser window running on an Apple Silicon macbook in 2026....
Exported and saved to disk and then ran without issue on a piece of hardware made in *1992*!
Now I need to do the reverse... make some software with a copy of VB installed on this old machine of mine and run it on my mac inside the browser.
