maken x 50 hertz problem
 

i can't find a patch for it is it possible to make it 60hertz without a patch

It might be.

Disassemble the 1st_read.bin, find the asm code for the frequency and change it. :)
Good luck !!!

how do i do that

It's too hard !

You have to disassemble 1st_read.bin (it means take all hexa values and then convert them to SH4 asm code). This part should take you about 2 years. Then, once you'll be able to read ASM code and you'll know DC's internal code, you might be able to find what's the screen initialization and its frequency. Then you'll have to change this code and reassemble your 1st_read.bin...
