Booster 쪽에서 DevHook v0.46을 내놓았군요.
The one and only Booster has now released a new version of DevHook for the PSP. The release name states ‘half install to internal Flash’, of course this sounds super risky so approach it with caution as of right now Devhook v0.45 does the job just fine with v2.71 firmware. You can download and discuss the release in this forum thread.
Remember to be very careful as we do not accept responsibility for anything that may result as of using this release.

새 펌웨어(v2.80)가 나오자마자 Booster 쪽에서 움직이는군요.
역시 소니에서 움직여야 재미가 있습니다. 
맥스콘솔에서 확인하세요.
