User Aims to Hack $800 Karaoke Machine

The author owns a TJ Karaoke B80 karaoke machine that hasn't been updated in over 4 years and wants to access the files to replace certain songs. They have extracted the hard drive from the machine, cloned the disk, and identified the partition structure. The author discovered that the machine uses an ARM STiH310 processor and attempted to emulate the system with QEMU without success.
