 | PS2 detects the disc as "PlayStation 2 disc" instead of "DVD Video" in the browser | Your PS2 has a modchip which is incorrectly preventing the DVD player from launching. You do not need this exploit for a console with a modchip, but if you really want to try it some modchips offer the ability to temporarily disable themselves (by holding start when booting for example). |
 | PS2 displays "unable to read disc"                                                 | Please try playing a real DVD movie disc to verify that your console's DVD laser works; doing this can also recalibrate the laser which might solve the issue, as [commented here](https://github.com/CTurt/FreeDVDBoot/issues/27). Also try the following PS2 setting `Version -> Console -> Diagnosis -> On` which can assist with laser problems.                                                                                                               |
 | PS2 freezes at black/red/green screen                                              | If your PS2 DVD laser is really worn out, or you are using something difficult to read like a dusty DVD+RW burned on high speed, it might take some time before uLaunchELF actually starts. Please try waiting 3 minutes or so, per [this comment](https://github.com/CTurt/FreeDVDBoot/issues/3#issuecomment-651337741)                                            |
+| PS2 "Reading disc" for long time                                                   | This reason could be having modchip. You can disable the modchip by having the console powered off, and then powering it on by holding down (instead of quickly pressing) the power button, until you hear the laser moving sound, them immediately let it go. This worked on an SCPH-9xxxx model. |
