OK I've just downloaded Moonshell 2 Beta 10 (english) from GBAtemp download section & after running the language select to choose english (& done nothing else)
I copied over 'moonshl2' folder & 'moonshl2.nds' to the
root diectory of my 8Gb MicroSD
Using YSMenu as my 'firmware' I started up Moonshl2.nds & it started up OK with no problem
I then tried starting up Moonshl2 AGAIN but this time using DSTT 'Fake-Killer Disabled' firmware & THAT started up OK
I then tried AGAIN but this time using DSision2, & THAT started up OK
I'm afraid all I can think of is that either you've done something wrong OR you havn't copied over all the files correctly OR perhaps you DON'T have a genuine DSTT card
I can't see it being because you're got FAT or FAT32 formatting on the card - because it runs fine on my 8Gb and my 2Gb cards
Have you tried saving all files & formatting the MicroSD card (NOT with Windows Formatter though - Use Panasonics formatter @
http://panasonic.jp/support/global/cs/sd/d..._formatter.html
)
The 'Extention memory not found' message is apparently normal
Sorry I couldn't be any more help
p.s. I'm using a DSTTi on a DSi - although I doubt THAT has anything to do with it
