I belive it may have to do with what Kernel you are using for your CFW, I get that error code when I try to use WifiSniffer, and WiFiController as well as other games or homebrews which were made for 1.50 - I am using cfw 5.00 and kernel 5.xx on a slim and get error 80020148
If you can use the 1.50 kernel try running the game under that (u have to have a fat psp to emulate earlier FW 1.50)
