What could have happened?

Hi guys, still here asking for help, and this time it's a huge problem. :o
My kid has a Nds and a R4 which I think could be a clone. Anyway, in the last few days there were troubles with games suddenly freezing and apparently troubles with the screen. I cleaned it, changed the protective film, then took it off, and so on. Yesterday, I tried a new game I had (Imagine Gymnastic) and it froze. I switch it off, then I discovered that the card was kind of formatted: it looked empty even if it was still full (no games list, but 3,8 Gb full).
I thought that the flashcard had gone, insert a new one, but it still shows a white screen with "Menu?" written on.
Could it be that the R4 is gone? do you know anything to bring it back to life or do I have to buy a new one? and, most important, could the troubles with the screen mean that also the Nds console is about leaving us apart?
Please, help me, my kid is desperate and I'm not exactly looking forward buying another one so soon.By the way: troubles with the screen and freezing games also come with original NDS card :(

An R4 original can hold upto a 2GB microSD card , A Clone R4 is a SDHC type and would say on the box and can hold upto a 16GB SDHC microSDMabe it would be best to do a full format of your microSD, Hope you have a backup of your gamesPanasonic SD Formatter, Will format your microSD chip cleanhttp://www.mediafire.com/download.php?nniuwomaetmRe-download your firmware and place the files back onto your microSD as well as gamesEDIT: If you say an original card dose it also , Mabe try to clean the pins somehow cotton swab mabe , are unsert and reinsert a card a few times with methylated spirits on the pins of the card

thank you so much! I'll try and let you know :)

Ok, For now just see how it gose!

trouble with the screen..? Has your kid been pulling the game card out while the game/ flash cart is running?

Well, I tried but nothing changed: R4 (definetely a clone) is still unreadable, even with a new flashcard, and original games keep on freezing.
What can I try now?
I don't know if my kid ever pulled off the card while it was still on; as far as me, I took it off after switching off the console while a game was frozen.
Any idea? please, help :(

If an original game is freezing, it sounds like your ds is not reading of the game card very wellIf you flaten a end of a cotton swab and use a dab of methylated spirits, see if you can clean the pins down the back of the DSIt could just be carbon issueIf not then it sounds like it's gowing out , Sorry if that's the case

the original games don't really freeze, but it looks like as if the screen doesn't work properly; it was a game I had on the flashcard that froze while it was creating the SAV. it stopped there, no way of doing anyhthing, so I switched the console off, then I realized that the card was kind of formatted (no list of games or software, but 3.8 giga full :o ).
I guess the console has gone... :'(

Did you do a full format with Panasonic SD Formatter ?The only time a microsd card is full with nothink on it is when they is coruption on the there somewhere, there for Panasonic SD Formatter will format it compleatlyIt could be the game that's causeing the problem , has the game bean Patched ?, Are is it a clean rom, game i mean...

I still haven't tried to format: I used a new flashcard I had, and it doesn' work. I know this next question will probably make you laugh, but what does Patched mean? it was a downloaded game, if I'm not wrong it was Imagine - journalist.

It mean's a game that has bean fixed, But sometimes not fixed well and can cause corruptionLike arm7 patched is a bugger for thatI have notest it also says DSI on the box, could be a problem alsoEDIT: I mean it could just be that one gameI mean also a format of your microSD chip, Click right on letter drive and see format

today I'll try to format the card and upload the software for clones, then I'll try to clean the inside pins of the console. I'll let you know.
Thank you so much for your help, you're just precious guys! :)

I don't see where cleaning the pins in an issue for now , sine its more clear to what the problem might be
