Problem with r4 and ds lite

it is probably because your sister has a different version of R4. They are the same things, but your sister might have an earlier version than you do. This is because, some versions dont work with some ds lites while others do.

have you installed the R4 system data on the memory card from the R4 website?
If all is well with the data on the card then you may have a connection problem between the sd card and R4 card or R4 card and ds. so investigate the cleanliness of the pins and the tightness of the cards in their sockets.
Some copy DS lites are fussy and don't work well with smart cards. A new motherboard would cure this but it will cost you £50-60

First you need to make sure you have the current firmware for the R4 card loaded onto the micro-sd card. I know that some R4 cards only accept up to a 2gb memory card so check and make sure you are using the correct micro card with the R4. When you have downloaded the firmware for your card you need to make some folders. Label them games...movies... music... etc.. making a folder for each one. Put the Mp3 files in the correct folder. When you use your R4 you will see three icons at the startup screen go to the one labeled multi-media... Moonshell will run the movies/music... you are ready to go ... hope this helps

Is your DS a DS Lite? If it is, open up your R4. Fold up a piece of paper and put it right behind the gold contacts (on the side facing away from the DS). Close it all up and it should work.

Email or Call Nintendo or send them your Ds, and they will give you a new one.

Hi grecko, Hope this helps, I've just bought a 4gb memory card for my daughter's ds so she can fit 58-60 games instead of 28 on a 2gb memory card and have downloaded and put a file onto the memory card before loading games onto it.

Supercard DS one have a site where you can download the files you need and it gives help. Guess it's the same if using an R4 supercard too but I bought an R4 card for partner preloaded with software.

first format your sd card
open the system file and send all the files to your sd card (4 or 5files)then send your games to card...and enjoy...there are tutorials on you tube.

the r4ds has a reset application when you press random buttons quickly and the r4 turns of sorry but i think you can turn it off by pressing the R BUTTON on the game loading screen... please pm me for any more help...

You have to put the R4 v1.18 kernel on the memory card for it to work.
R4 web site is http://r4ds.cn/
In the download section is the r4 manual follow that and you should be ok.

I don't have a solution but I have the exact same issue. On my co-workers DS my R4 works like a champ on my daughters R4 it gets stuck @ loading.
