Well, I've tested the games that I had reported before with rev89 in PS3 PAL 60GB model. There is nothing changed but only MGS3 is a little bit different, I'll explain end of this post. Here is the result with rev 89 in ps3 pal:
SLUS_213.70 - Megaman X Collection(X1-X6) - NTSC - working - Rev. 89 - No issues, not patched.
SLUS_209.60 - Megaman X 8 - NTSC - working - Rev. 89 - No issues, not patched.
SLES_528.32 - Megaman XCM - PAL - working - Rev. 89 - No issues, not patched.
SLES_514.34 - Slient Hill 3 - PAL - not working - Rev. 89 - crash at first "Slient Hill 3" title (with or without patching).
SCES_520.04 - Kill Zone (Multi) - PAL - working - Rev. 89 - with dnas patch by usb util 2.0. Intro cinematic is choppy, but it is not problem, the video is watchable anyway
SLES_553.80 - Sonic Unleashed - PAL - not working - Rev. 89 - only black/blank screen (with ot without patching)
SLPM_656.21 - Street Fighter 3 - NTSC J - working - Rev. 89 - No issues, not patched.
SCUS_973.28 - Gran Turismo 4 - NTSC - working - Rev. 89 - with hd patch. But it freezes on some racing tracks, and I can't load those maps never. Those tracks are GranTurismoMode=>License=>B License=>Tracks 3, 5 and 7.
SCUS_971.24 - Jak and Dexter, The Precursor Legacy - NTSC - not working - Rev. 89 - not patched, the "naughty dog" intro was shown up, after that my usb hdd's power led turned off
SLPS_253.47 - King of Fighters 2002 - NTSC J - working - Rev. 89 - no issues, not patched
SLES_820.42 - Meta Gear Solid 3 Disc 1 - PAL - not working - Rev. 89 - only menu and videos are working, the gameplay is not loading.
There is a little difference between rev 89 and older revisions for metal gear solid 3. Before rev 89, ps3 is crashing when the first gameplay is starting to load after the first video, so I had to do hard reset by holding shut down button a few sec.. With rev 89, the gameplay is not loading but, ps3 is not crashing, there is only blank screen.
