It is an interesting piece of software, but what is the purpose? For someone that wants to emulate a Pentium computer there are many better ways, for having fun there are many better ways, so what is left for this particular one?
I like reading through disassemblies of DOS games and figuring out how things work. It's fun recognizing C programming patterns in the assembly. There's something a little charming about looking up what writing to some VGA control register is supposed to do...and I haven't found anyone else who actually thought any of that sounded like fun.
Someday, I'll put together a series of blog posts about it, and maybe I'll have some code that I actually want to show off, but right now I'm just having fun.
There's no accounting for taste. Building something like this sounds a lot more fun to me than most programming projects that I hear other people talk about as "fun". What would you have chosen to do instead?
