I wrote an HC11 Microcontroller emulator for a project at uni.
In VB of all things and it was also pretty much one big switch statement.

I also wrote an assembler for it!

bugger me!

I wrote an in-line assembler plugin for VB6 (using the Win32 API 'copymemory' a LOT!). I wouldn't know where to start now.

It's funny you should mention microcontroller emus - I've recently been thinking of writing an Arduino emu for Linux to save me uploading code to it every time I want to check something out.

Ahhh yes.. assembler creation
in my previous job, years ago, we wrote software for an embedded board running on an HD64180 (a kind of super Z80).

We were using an old commercial DOS Z80 macro assembler from the early 80s, that kind of sort of worked OK under Windows XP, as long as you didn't sneeze.

It had really stupid problems, like cryptic error messages, and the number of imported symbols you could use depended on how many environment variables were defined in windows (!!).

Since it used its own wacky syntax, we couldn't easily port our code base to a different Z80 assembler, so I wrote my own syntax compatible Z80 macro assembler and linker from scratch in my spare time.

Happy days.

Ahhh
I long for the days when I was a *proper* programmer instead of the dot net crap I do now (although in fairness - Visual Studio is one slick IDE and C# is quite nice as it goes, it's just about the only thing I can stomach using Windows for these days).

I'm still in embedded software engineering
doing low level stuff for digibox (satellite, freeview, IPTV etc.) chipsets.

I much prefer embedded stuff.
