What is the goal here with this library, and how does it work to mount drives or disc images?

 

[proconsule54]

Just like libusbhsfs for the usb mass storage

To play DVD-Video games on a Switch, like these: https://www.mobygames.com/platform/dvd-player/

For this there is the great libusbhsfs that is used on 90% of the homebrew

This is fascinating, thank you for the work!

 

[proconsule54]

I will update and release also as nro the example, so anyone can test out if the dvd drive is compatible

 

[proconsule54]

Working on UDF, is a bit more complex then iso9660 but i got directory listing. Good
I will release an update soon

 

[linuxares]

Tell me if you need Blu-rays tested out. I got an external bluray reader!
libaacs is available from VLC and the keydb.cfg should be googled to find.

• Added UDF Support
• Added an example nro for testing drive/support

This is if NO Drive is detected

This is if no disc or other problem (BUT DRIVE IS DETECTED)

This is all ok, Drive will work well with the lib

@linuxares send me screen of your tests when you have done it

Didn't want to open a github issue for this but can confirm this cheap external works on 0.0.4

vendor_id: MATSHITA
product_id: DVD-RAM UJ8B0AW
product_revision: 1.00
serial_number: 11070400

Eject works as expected too! Awesome work so far. This disc should be reporting 24 tracks but unsure if I tripped the amount of printing it's expecting or something else.
