Chrono trigger patch ds lazy

Hello, I'm a bit of a novice and I'm having a bit of trouble patching chrono trigger with this max patcher kit, after I upload chrono trigger with ds lazy it opens a folder, Inside there is an arm7 bat file, It says to copy the arm 7 file and replace the one that is there, how do I do this and where do I get the file from to replace it with ? Does anyone think they could tell me in simple language how to do this ? Thank you very much - Daniel :-[

You get the other arm7 bin file from another game. What exactly are you hoping to achieve with this?

I'm trying to get chrono trigger to work on the r4 as I said I am not computer literate, so I should replace the arm7 file in the folder with the arm7 file from chrono trigger then repack it ? I will look for this arm 7 file then, If I copy and paste it then delete the one I don't want will that replace it ?

i will to finish game with my brain. do like that!
if i can, i must can.

where do i look for this other arm 7 file then what steps do i take to replace it ?

Would be easier to update your cheat database from http://cheats.gbatemp.net/.
