Any Programs to Download to make Oppo 83SE and 105D Region Free


I have an Oppo 83SE and Oppo 105D.  Inquiry on any programs to download that I could use to make these two models Region Free.  I only have two dvds (non blu ray) that are English.  It would not pay to get kits that would involve taking these apart.

unsupported by OPPO. USE AT YOUR OWN RISK.

This will make the player region-free for DVDs, but not for Blu-ray.

It is a tiny bit of software that has worked on every OPPO Blu-ray player so far. Some use it (I have not) and find it to be trouble free.

Follow the directions closely. It must be copied to a CD-R, not a burnable DVD. Save the disc because you may need to install it again after a firmware update, although I can't remember the last time I had to do that.

You load the disc, it waits a second then ejects the tray again. That's all: it's done.
Why not just call Oppo and ask for a solution? They are very customer friendly and don't care where you you bought the unit. Sometimes, these quick-fix solutions can do more harm than good. 
superdisk is good for dvd multi-zone

if you want to make bluray multi too, this is good
