Additional Comments
Ran 'winetricks ie7 wmp10 pdh vcrun2008' but no go, the roblox4linux.sh script doesn't work as the URLs have been changed.
The game appears to work (only briefly tested) when you log in as a guest.
You don't appear to be able to login as a user at all. Even if you register via your Linux browser, trying to login (via the Roblox browser window, or via IE6 running in that prefix) will just get you a ton of:
fixme:ole:CoCreateInstance no instance created for interface {30a5fb78-e11f-11d1-9064-00c04fd9189d} of class {adc6cb82-424c-11d2-952a-00c04fa34f05}, hres is 0x80004002
messages from Wine... and eventually a blank page.
Trying to use the native dxtrans.dll and dxtmsft.dll just lead to a long line of crashes that I don't feel like debugging atm.
