RJ Tech RJ-1000KII

Hello everyone,

I recently bought an RJ-1000KII karaoke player; however, there are so many songs in languages that I couldn't read. I was thinking about of keeping the same menu but try to replace the songs with the different MIDI songs in the language that I want. Is there a tool or any idea on how to make this work?

Please give me some advices. Thanks so much!!!!!
