Critical error: Invalid Device

[DragonNeos]

Since it is a very rare error, when I do encounter the issue, I just close and restart the emulator. After restarting the emulator, there aren't any issues when I select a game or application.

Although the option "Unpack PBP on load" now works with encrypted EBOOT.PBP files, it should probably be listed somewhere on the README.txt that the -Xmx Size should be increased to a greater capacity (depending on the size of the EBOOT) when using this option or else the following occurs:

Code:

Exception in thread "Umd Browser - Umd Info Loader" java.lang.OutOfMemoryError: Java heap space

For example, I had to raise the -Xmx Size to 2560 MB in order for the emulator to dump the contents of Final Fantasy Type-0 Trial [Zeroshiki] into the unpacked-pbp directory.

A similar error may appear when selecting an encrypted EBOOT.PBP from the UMD Browser:

The first error seems to occur when the -Xmx Size is never touched (UMD Browser displays a white screen and is frozen). The second error seems to occur after the -Xmx Size has changed to a lower value (I lowered the value from 2560 MB back to 1024 MB). Both cases require using the Task Manager to close the emulator.
