In order of importance this is how I'd like to do things
1. Remove all of the assembler - it blocks anyone not using a 32 bit machine from the yummy goodness euphoric provides
2. Fix the configure file and the make system. It's borked badly
3. Port the code over to use SDL for the GUI - it gives a uniformity across platforms
4. Use the SDL audio system over libarts for noise generation
5. Add a desktop icon. I don't know if the Win32 version has this, but if it does, we can use that.
Knowing me, I'll do it in the order 2-[1<->5]-3-4
The SDL aspect is the more interesting. xeuphoric (Linux) when run produces this tiny little window which doesn't really make for an enjoyable experience. I have no experience of euphoric for Windows, but can't see them standing for a titchy window. By shifting the lot over to SDL, we have a uniform version for all platforms.
Where can you lovely people help? Well, the assembler is going to be the toughest and hardest part IMO. If anyone has a copy of asm2c, could they run the files through it? Failing that, I'll have to dig out my books

If there isn't a desktop icon, there needs to be one - I was thinking of the O with the slash through it as a 32x32 png. I'm not an artist by any stretch of any imagination.
Euphoric is not dead
