How much space required to flash a WM6 ROM?

[isihie]

I have an XDA Mini S with no additional space (didn't buy a mini-sd card for it). In System->Memory->Storage it says I have 47.46 MB total. Is that OK for flashing WM6 on it. Btw, it should have 64MB, I'm not sure why it says 47.46 MB (probably because it doesn't add the space occupied by the ROM?).

Thanky you

You don't need additional space, as the ROM is flashed to your Flash ROM directly.

The missing space is due to Extension ROM (10MB), some files and database copied during first cold start, and the applications installed from Extension ROM on first cold start.

and you´ll loose everything stored on your wizard during flashing process! so backup your contacts ...
