I have the same problem with a new DSi console I just bought
I got a R4i SDHC Upgrade Revolution V1.4 card
Extracted and Copy all files version R4i v1.25b from http://www.r4i-sdhc.com/downloade.asp
to my SD card
Insert the card into the DSi and I tap on the Star Wars
Alliance I get a black screen saying 'An error has occurred. Press and hold the
POWER button to turn the system off.
Please refer to teh Nintendo DSi Operations Manual for Details'.
I have tried this different times formatting the card and
still no joy
Will it be a faulty cartridge or Nintendo has upgraded their
firmware so that latest firmware R4i v1.25b doesn't work?
Thanks a million
