Hacking Cheat dat not reading cheats

[Joojii]

Okay so I have the cheat.dat from http://gbatemp.net/index.php?download=5551
I loaded the cheat.dat on my m3 ds simply. It reads most the games listed on there execept some. Such as Yu-gi-oh 5d, and pokemon platnium.
Any reasons why it wouldn't? I also have the latest r4 firmware changed into m3 format. I also tried it with the latest m3 firmware but with still no result. Can anyone help me please?

this is why U/E cheats .dat are no longer supported by Narin
those people who upload this shoupd put a note on such issue
it is damn bloody irresponsible for them just to upload some .dat which give people problem

quick solution delete all the games you don't play

Has to do with the r4 cheat system limits. Get ysmenu or delete a bunch of cheats that you don't use from the cheat.dat file.

What's ys menu and what does it do? And could you link me?
