Just updates your DSi to the latest firmware.
At this moment you can't jailbreak the dsi. Refer to dsibrew.org for updates on it though.
i also have a dsi XL i also formatted the memory it will only erase photos music and songs it does not erase updates or downloads
All system updates for the Nintendo DSi are provided free of charge.
No, Nintendo's updates block Flash carts ther not going to let you use an old firmware.
there is no netflix app for ds or dsi, only nintendo 3ds
If it can update, you've got 1.3 but it updates to 1.4 anyway.
The latest firmware updates will prevent illegal copies of games from being played.
It's not possible, I did a system update - formatting the system doesn't remove the updates just all userdata.
That is correct. Updates usually include anti-piracy measures, and disable various flashcards.
You could get a R4 Chip (If you have Nintendo Ds or Nintendo DSI) It costs £35 (about) It is illegal but you can put up to 40 games on it! (Google R4) If you have a DSi or DSi XL its a bit harder. You have to get a R4i - But the thing is Nintendo Dsi and Nintendo DSi XL get updates which patch your R4i and stop it working. The only way to get it to work on a DSi is to NEVER update your handheald, updating is a manual process so it wont automaticly patch your R4i This is the DS option. If you want to get any game on the wii for free you need to solder chips in your wii, so its more difficult.
you cannot get a dsi with dsi points
