With all talks of Custom Firmwares rounding the PSP scene, jas0nuk has thought of making apps that will make the contribute to the hype. First, he came up with the Custom Firmware Recovery.ELF Tester that allowed custom firmware users to test a recovery.elf file in the memory stick before doing it in the flash memory. Today, he presents us with a "module adds 'extensions' to your 1.50 VSH/XMB that can be accessed via keypresses".

VSHExtender v0.1 is partially based on Booster's code but was rewritten for firmware 1.5. The developer suggests that this application be used with Dark_AleX's custom firmware or any custom firmware which allows users to add external modules (Harleyg's counted).

jas0nuk admits that the features of the VSHExtender may not seem impressive for now, but with this base he says that it will be easier for him to add new features later on. With that, here are the features:

- Press HOME + SELECT in the XMB to change the CPU and GPU speeds, steps are 133/66, 222/111, 266/133, and 333/166
- Press HOME + CIRCLE in the XMB to change the CPU speed to 30MHz and the GPU to 50MHz. This makes the XMB become a little laggy but is fine for playing AT3 music or AVC video as this is hardware decoded
- Press HOME + L TRIGGER to execute ms0:/PSP/SYSTEM/DEVBOOT.PBP - this is yet ANOTHER way of booting DevHook instantly into 2.71 firmware, but now you can do it after startup
- Press HOME + R TRIGGER to get battery percentage, voltage and temperature information.
