Lik-sang is out of stock.
but yes, the messiah chip is available.. and by now, quite easily. sony only stopped it in UK and USA. doesn't keep people from getting them at all, tho.
I ordered 2 of them in UK recently, got both within 5 days. of course, they ARE expensive.. but well worth it, it really boots any game, be it import or cdr/dvd-r on the first try without any probs.
just be aware it's a bitch to install on some models, and only works on a single US model (a certain V4 series). works on all PAL models, tho.
