what mods are in the hax rom?

[rick-maria]

I came here because I wanted a screen saver feature for my ancient VT100.
The one you hacked in is just perfect!!

But I appears there are more changes in the haxrom than just the screensaver, hence the question:
what other differences are there? I am unable to read 8080 asm, sorry!

Also, if I were to burn this code into an actual ROM - what ROM should it replace on the vt100 hw?

Thanks,
Rick
