Can any #retrocomputing nerd suggest a tool to dump every register on a #vga from #dos into a text file? Ideally also the state of the int10 interface.

Ideally I want to be able to sample the state of the VGA at different states of brokenness.

I have read the osdev wiki on the vga and I'm pretty confident I can write something myself, but I'd rather use something that is known to work so I'm not compounding the uncertainty in my debugging efforts.

Thanks! ♥️

Thoughts on making a game in CGA (usually 4 colours at 320x200 pixels):

* The magenta and cyan palette was ugly by 1990 but feels fresh in 2025. Colour combinations really do go in and out of fashion.

* It's a lot of fun making games for low resolution. A pleasant chunky feel and forces really considered UI choices.

* Good CGA art is hard. I think I did OK but lots of solid blocks of colour. A lot of the beauty of CGA is in dithering.

* I cheated on framerates

Here's the original, unaltered U.S. floppy disk version of SimCity Classic for DOS. With file dates from August of 1993, this is the very first revision. Sorry for the delay, but I imported these from the USA. For the retro collectors!
