Fridge does not start gives error ds

I think you mean a dh error code which is a defrost problem either your sensor or heater is bad

Er/ds=Failure of defrost sensor or there is a cut of short in circuit wire. You would have to use a multimeter to perform continuity tests on the sensor to assure it is working with the sensor and the machine unpluged. If you have any further questions message me back I await your reply.
Thanks again,
Rick
p.s if you have any further questions please also include the full model number of the unit so that I may supply a schematic for you as well showingg the location of the sensor in your unit.

either your card reader is damaged or you downloaded the new system update wich prevents use of the r4 card. please rate my solution, good or bad.

Check you Dsi system date and time,this need to be accurate for R4 card to work properly,put that date and time since it was giving that error,wont work with todays date.Also update your system with new and original software.

Are you download real programs for R4? Go to www.r4ds.com to download it,it will better because i download it at there too and it can play

I use to have similar problems with my DS Card :(. In the end, I end up buying a new one - I personally use http://www.NDS-Gear.com

Apparently, the Sd/tf message occurs when there is a problem with the connection between the micro SD and the DS Card or between the DS card and the DS. You can try giving your micro SD a good clean ( give it a good blow) and see if that makes any difference. Also, I heard that sticking some papers at the back of the DS Card works for some people. If nne of this work, you would robably want to buy a new one or try and get a repalcement from your seller.

remove game card and place ds in warm place overnight ...damp is causing this problem

nope thats a coding error youll have to return and swap for a new one
