UMD Emulator (previously known as Fast Loader) does not trick. UMD Emulator bypasses the firmware updates. In other words, it wont ask you to update inorder to play. SXT Version Changer is the one that tricks the PSP into thinking its the latest firmware. Unfortunately, with new games coming out such as GTA, SOCOM, etc. (it varies), it requires 2.0 files inorder to play. WIthout a 2.0 or higher, you're out of luck if you want to use your 1.5 firmware.
So even with UMD Emulator, I'm SOL.
