Nintendo DSi has some potential problems.

Said By GBAtemp

Reports are flying in this morning that the new DSi handheld is incapable of booting existing flash carts. Our friend ahtin at Hacken.cc who has got his hands on a brand new DSi, has tested both the popular R4 DS and EZ Flash V.

ahtin has reported that the R4 DS (an auto-booting slot-1 cart), when inserted into the DSi, in fact does NOT automatically boot up, and fails to appear at all in the new revamped DSi main menu (which is normal behaviour for an auto-booting cart). The EZ Flash V on the other hand (a non auto-booting slot-1 cart), does in fact show in the DSi's main menu, but when launched generates an error which prevents it from loading any further.

Whether or not the new flash cart "prevention" on the DSi can be disabled or worked around is yet to be determined. Once more people get their hands on the new Nintendo handheld revision, we'll undoubtedly learn more about why this is happening. Perhaps it could be something as simple as an update in the carts loader/firmware (at least in the case of the EZ-V), or perhaps something a modified firmware (ala. FlashMe) could fix. But of course, only time will tell.

Hacken.cc have not reported results on any other flash kits. Stay tuned to GBAtemp for any further news, as we'll keep you posted on any developments.

UPDATE!: ahtin has informed me personally of his latest tests. Unfortunately it's not good news! Just take a look at the long list of flash carts that have ALSO FAILED on the DSi...

CycloDS - Failed
G6 DS Real - Failed
M3 DS Real - Failed
Supercard DS One - Failed
iTouch DS - Failed
FCard - Failed
NCard - Failed
M3 DS Simply - Failed
U2DS - Failed

Also, importers please note that there is no English language option in the firmware - only Japanese, so be careful!

Speaking to Pocket Gamer, an obviously-doesn't-want-to-be-named "developer" has said there may be a problem or two regarding DS/DSi compatibility. This developer, you see, is currently developing a game for the DS. Their game obviously runs just fine on DS, but on the DSi, it keeps freezing up, and as a result is stuck in development limbo, Nintendo refusing to certify it. Nintendo, predictably, are saying "All DS titles are compatible with DSi", but if a game in development will run on DS but not DSi, might there be some finished games that run into problems as well?

It still costs 40 bucks more than the DS Lite and offers nothing more as a games machine.
