Can't play downloaded HB's
I'm new to the PSP world but I've done a fair amount of reading; hopefully so you don't get too pissed at me for being a noob. I understand the difference between 1.5 & 2.0 but little is mentioned about 1.51 & 1.52. I have tried several HB's including the old Legion pack and the latest XPloit (KXSploit_Homebrew_Pack_V 3_0_PSP_V1_5.rar) but have had no luck!
I create the folders on the memory stick as described and everything shows up as I expect on the PSP. However, it errors out on every emulator or HB that I try. Is my fix to upgrade to 2.0 and downgrade to 1.5?
Thanks for any advice you can offer!
