Ok, I got magic 3.1 installed by local gameshop Like so many others I do have problems with it, but intrestingly they seemed to accumulate until nothing worked and some problems do point at laser problems, but then they kinda half fixed which does not sound like mechanical laser problem and others point clearly to mod chip or its installation: First everything seemed ok'ish, - PS1 backups OK - PS2 originals OK - CD-R's sometimes booted only after 10 tries and do freeze very often during loading or loading takes ages. Then one day CD-R's that did earlier boot, started to result more and more: - red 'insert ps2 disk' messages - green DVD 'can not read disk' messages - browser screen Originals did still boot Then PS2 originals stopped booting also and everyting I tried to boot resulted browser or green DVD message. I turned the chip off from switch (read below) and tried to boot (worked ok with PS2 originals in off-mode earlier) It did not boot at all, nada... only black screen... Turned chip back on and tried to boot few games, on one boot I got this: 1. Old playstation logo, but smaller than in ps1 boot without any text 2. PS2 logo like it is in the side of the machine (made of blue lines) 3. 'Select language' in several different languages. 4. timezone etc settings. After this it again started to work somewhat, PS2 originals loading sometimes not, CD-R's needing multiple boots, sometimes red screen. Same CD-R would boot at first time, then half hour later not at all no matter how many tries etc. The weird thing about my magic 3.1 is that the shop had only 3.0's I wanted 3.1 and they said they'd get one for me. When I got my machine back they'd installed a switch, like the main power switch, to front of the machine to turn chip on-off, which is weird due the 3.1 should have this feature already? I opened the machine and checked the dust situation on laser lens and around, found absolutely none on the lens but cleaned it with dry q-tip anyway, didn't affect the loading/booting for good or bad. My PS2 is PAL and I suppose V4 (8 screws in bottom with stamped electrical warning and 4 small screws on DVD cover lid) Any help or suggestions are welcome as I live in Italy and do not speak the language good enough to have a debate with the gameshop dudes. Thanks.
