My son's Dsi XL just started to not recognize when a game cartridge is inserted, it will appear if I push and hold the cartridge down, but not stay on as supposed to.

That sounds like the speed of the game console's processor is not up to the games needed speed that is playing, battling takes allot of computing power.

DS, DSi and DSiXL have the same game (cartridge)

Make sure that you have a Nintendo DS cartridge connected to the Action Replay.

It might be that the pins that read the cartridge have been pushed too far down.

You could attempt to fix it yourself by opening the console up and lifting/bending the pins slightly.
However this isnt recommended unless you have done anthing similair before.

Ideally you should contact either the store it was bought from and use any warranty that the console is under or contact nintendo directly.

Make sure it is inserted proparly thn switch on and when you double tap it on the home it should say datel and after that it finishes going through the codes you double tap on codes and it should bring up the codes with that game in the cartridge and you are using Action Replay DSi Right.

my dsi won't play any games HELP

1. Action Replay Not Staying Inserted:
   • The issue with the Action Replay not staying inserted into the DSi may be due to a loose or damaged cartridge slot on the DSi or an issue with the Action Replay cartridge itself.
   • Check the Action Replay cartridge for any visible damage, including bent pins or connectors. If you find any, it may need to be repaired or replaced.
   • Try inserting other game cartridges into your DSi to see if they fit securely. If other cartridges also don't stay in place, it could indicate a problem with the DSi's cartridge slot.
2. DSi Not Recognizing Game Cartridge:
   • If your DSi doesn't recognize that there's a game in the slot, this could be related to the Action Replay cartridge, or it could be a more general issue with the DSi.
   • Test this issue with regular game cartridges that are known to work. If the DSi still doesn't recognize them, there may be a problem with the cartridge slot.
   • If other game cartridges work fine, the issue may be specific to the Action Replay. In this case, you should contact the manufacturer or distributor for support or a replacement.

In either case, if the problem persists, you may want to consider having your DSi and Action Replay inspected or repaired by a professional technician, or contact Nintendo's customer support for further assistance. Make sure to follow their guidance and ensure that your DSi and accessories are in good working condition.

sounds like the clip is broken that holds it down. you could try to put it in there and move the game back and forth inside (not much tho) till it stays. if it dosent work take it back as not not void the warenty ( asuming u have one) if u dont have a warenty then i say get the rite screw socets (flat head electronic screws wil work for now) and try to put it back on

Everyone i just found out how to fix a black or white dsi that is frozen and wont turn off!!
Step one:unplug dsi (if it is charging)
step two:close the dsi
step three:once it is closed turn volume down all the way witout opening
step four:set the dsi in front of a fan vent or someplace it will get a breeze
step five:open the dsi and hold power switch for like 6 to 10 seconds
(even when it turns off keep holding it for a couple more seconds)
now you an plug it back in and turn it on and VAWALä
hope this helped:)
