Humma Kavula has released his first update today, namely PSP Fastloader v0.5d. Changes include increased .iSO compatability, the HOME button fixed, the DEBUG button removed, and finally support for both v1.00 and v1.50 PSP firmware. Please post all related feedback in our on-going official PSP Fastloader Compatability List and enjoy!
NOTE: It appears the v1.00 support may not be complete yet as we've received reports already that with v0.5d the .iSO won't load, and if you remove the UMD from the drive it still says initializing... more to come.
