Wander for DOS and/or web

[ahope1]

Not sure if this is the right place to say this -- if not, then please delete/ignore -- but I wanted to mention that I very crudely and ignorantly hacked the code to make it compile with DJGPP for DOS: https://drive.google.com/file/d/0B3AP_xKS4XgAbEg3V000eklOZ00/view?usp=sharing

But in doing so, and because I didn't really know what I was doing (I was just commenting stuff out, mainly!), I broke SAVE and RESTORE. Anyone know the proper way to do a DOS port?

I then packaged the broken DOS port using em-dosbox tools to create a version of Wander that was playable online: https://s3.amazonaws.com/wander1974/wander.html

I wanted to bypass em-dosbox and instead do a pure-emscripten version, but I know very little about emscripten, and couldn't figure out how to create a proper text-input field, as opposed to the default modal page-obscuring Javascript popup dialog box! Can anyone help?
