iR Shell v5.2 is released. iR Shell is an application created by "AhMan". When properly installed on a PSP, it can completely replace the PSP's usual XMB. iR Shell can run applications while using it and switch back to the iR Shell menu instantly. This means one can combine application's functionality with iR Shell's functionality.
