Try blowing into the game a bit. thats what I have to do. and it works fine 'sometimes' its not 100% thing though.
YOu know I was very supicious about blowing, thinking like seriously how can the contacts be dirty enough that blowing would help, or like if blowing helps how does it work in my system. but after blowing in both the power save adapter and cart mildly, it just like started working (not 100% of the time, but a few time at least), no freaking idea if its just coincidence or what but hey I ain't complaining, thanks salor moon.
P.S. MOre cheats are now available since they were previously listed
added poke miles 9999999
added 999 master balls in slot 1
ton of recovery item changes like 999 rare candies in slot 1
and max berries in all slots
and as I write this I can't get my x to work any more, it shows my backup save, but the spiner icon keeps spinning for power saves and cheats, and then eventually switches to no hardware found, if any one figures out a more reliable way to make this work, pleas let us know.
[EDIT] cleaning with q-tip soaked a but in 91% alch (im sure 60 is fine) and then dryed with other end and air blown with compressed air seems to have helped be more consistant I took it out and tried multiple times its working better,
