Again another donation another feature. Thanks for donating!

-updated to version 2.5-

*Fixed a bug in DM that could cause a fatal read error when using devices with under 8GB size
*Added a PADHOOK pattern for Batman:Vengeance
*Added a screenshot feature
 This feature can be enabled/disabled via the DM(L) config
 Press R+Z on the fourth controller to take a screenshot any time!
 Screenshots will be saved to device:/screenshots in the YPbPr format, you can use my tool to convert them.
