Two days ago I mentioned that Half Byte Loader was a good way to still run homebrews on official firmware 6.60, if you’re one of the poor souls who updated. It turns out I was wrong, as HBL, for now, doesn’t run on Firmware 6.60, due to some tricky changes in the PSP firmware. JJS found a workaround however and published a Debug version of HBL, that runs on 6.60. Since the download also contains a patch file, it is fairly easy to compile a “release” build for those who want to, but JJS announced he still wants to add a few tweaks before we feel confident to publish a release build.
This is of course, until a downgrader or a Hen appear for 6.60, which should happen sooner than later
