Hello, I found some Files on my SD-Card in the "SD:\emuMMC\BK00\eMMC" directory are these untouched Backups?
What are these files?

 

[ut2k4master]

a backup, yes

 

[masagrator]

This is file based emummc i think

Backup is usually stored in Backup folder

Backup is usually stored in Backup folder

The crazy thing is, that there is also a seperat partition on the SD-card, i tink this is the EmuMMC source.

Can I may check if this is a real working backup up and if this is for SysMMC or EmuMMC?

Thank you
