Developer homemister visited the QJ.NET Forums earlier to announce the release of LuaPlayerHM7. Unlike the previous release from last May, however, this latest build is readily available for use among the PSP community.

Aside from routine bug fixes, this release also enjoys the addition of several new functions. We've posted part of LuaPlayerHM7's changelog here for your viewing - the rest is available in homemister's original post:

* Added System.loadPrxKernel(file name) Will load a PRX into the kernel memory. Allows kernel functions to be used.
