JJS returns to his roots with a new version of PSPdisp — PSPdisp v0.5.1 — that is now compatible with Half Byte Loader! Mind you PSPdisp is a little slower under HBL than a custom firmware. But hey, them’s the breaks.

PSPdisp allows your PSP to act as an additional display monitor for Windows. You can send remote keyboard/mouse commands to the PC and even stream audio too.



New features on the PSP:

•support for Half Byte Loader, but with these limitations
◦only WLAN mode usable, no USB mode
◦image streaming is about 30-50% slower than on Custom Firmware
◦audio sample rates other than 44 kHz not available on all firmwares
◦screen brightness cannot be changed through the menu
◦HOME button must be pressed twice for the menu to appear
New features on the PC:

•libusb driver updated to the latest version, it now works on 64 bit systems with active driver signature enforcement
