SodR has released a new version of his UMD Tool for the PSP.
Heres whats new/info:
I was playing around with MPHGL and successfully managed to patch it to run at 333MHz. You can just simply replace the old mphloader.prx with my new one to play at full speed yourself. You don't beleve me? Try to first launch gta with mph's orginal prx and then replace it with mine. You WILL directly feel a difference.
New functions:
- Launch MPHGL at 333MHz (use patched mphloader.prx)
- Test that the UMD and UMD drive works properly
