If the old hardware does blitting and drawing shapes with hardware (especially with windows 3.1 driver
installed) , does it mean it is not possible to emulate it and make it look the same on a modern platform pc?
Thanks

In theory it's possible (you can emulate anything). But I don't see the point?
Windows 3.1 is designed to look exactly the same on all devices, regardless of how much acceleration they use.
Whether you do blitting and drawing shapes in hardware or software, it looks the same. So I don't really see the point in emulating hardware acceleration, since technically that is what Windows already does with the default VGA driver.
On the bios level, for example, the avance logic chip does polygon flood filling a different way.
I don't know why. Perhaps just an illusion, I am a perfectionist on emulators 😀
I guess that means you'd have to write your own patch and compile the sources with your emulated hardware accelerator included (like it has been done for S3/Paradise/ET3000/ET4000 chipsets)
