Ha, Victory 
"Speedy" emulation added in r45684 - builds will be available in half an hour or so at https://github.com/VICE-Team/svn-mirror/releases/tag/r45684
while debugging this, i also found a little bug in the ROM - it tries to detect 16/32/64k RAM, but when there are 16, it will detect 32 instead. It can be fixed with this small patch:
* = $92e2
LDY #0
JSR $0800
CMP #5
BNE $92FB
DEC $D0
without this, "freezing" will crash when there are only 16k RAM
using the above build, you can try it like this:
xplus4 -cartspeedy speedy.bin
use alt-z to freeze - note that it takes a second or two before the freeze menu shows up. I have also not tested yet if saving snapshots to tape or disk actually works
