Well to convert PAL save to NTCS you need to use some save extraction software like SaveGame Manager GX which requires hacking your Wii too. Also some game saves cant be converted to other regions, they will become corrupt. (I dont know if SS is one of those.)
Also another thing, that could Ubisoft do is to let Jesper Kyd to compose AC soundtrack again. His music was is awesone, it is actually a thing that I have enjoyed the most in the series. Lorne Balfe's music was a big disappointment for me.
And If you like to, you can than mount that image (with dism on W7/8) and integrate updates with this really handy tool: http://windows-update-checker.com/ (guide is here: http://www.windows-update-checker.com/FAQ/How to integrate updates into a DVD image.htm.
You have to do sysprep and then make image (for example prom rescue cd).
Sysprep makes that image working on pcs with different hardware.
EDIT: Works with W7/8 and probably vista too.
I didn't know they made an MSU cart for the Genesis.... I knew about the SNES one and the library for that is rather large but the Genesis one has very few games
