Tales of VS. 5.55 workaround

I got Tales of VS .cso (Play-asia doesn't ship to where I live) and it won't run. So I traced the problem back to the fact that I need to spoof my firmware version which I'm not bothered to do, is there any other workaround availible. I want to play it so badly! Any ideas?

Try this.... Dont know if it will work but you may get lucky....http://www.psp-hacks.com/2009/10/07/eboot-bin-patcher-v1-0-released-play-5-55-6-00-games-on-5-00-m33-6-and-other-cfws/
