Hey man, if you're looking for the fonts I had them on a similar thing I done a while ago. Only normal size unfortunately https://github.com/padraigfl/packard-belle/tree/master/src/_... Cant remember where I sourced them from but it's probably in the code somewhere, the MSSansSerif ones are pixel perfect as far as I'm aware. It outputted CSS to be used independently but it was very much a secondary concern, pretty sure I'd be the only person who knows how to use it without backtracking from the react bits https://github.com/padraigfl/packard-belle/blob/master/css/w... the data-uris might be useful, will have a look through your issues to see if I can help with anything!
Here's the attempt at a Windows 98 recreation I done with it feel free to take whatever from it:

Tried doing a design system thing too but got lazy:
