Developer's note:

HBL Revision 99 comes with some major improvements. First, the dreaded “sceCtrlPeekBufferPositive” (the function that basically makes emulators run at full speed) should now be available on all models of PSP. Remember, it wasn’t correctly working on PSP 1000/2000/3000 on 6.20. Although there are still a few differences in the quality of syscall estimations for these models on this specific firmware, this major function is now working on all models, and you should all be able to enjoy full speed on your favorite emulators. This makes the “”override_sceCtrlPeekBufferPositive” obsolete, and if it hasn’t been done yet, this option will be removed from HBL in a future update (since it doesn’t do anything anymore).

This version also fixes most issues with the PSP HOME button, thanks to a patch by Nymphaea. It finally allows to run HBL from the memstick on a pspgo, and should fix the issue with controls introduced in R97.

I haven’t fully tested this release, but it’s been tested by a few people already, so I believe it’s good to go. For those who ask, R98 was released a few hours ago, but had a bug that prevented it to work correctly on a 6.20 PSPGo
