UPDATE : patch added to remove annoying screen, see below 

Mere hours after Final Fantasy Crystal Chronicles: Ring of Fates hit store shelves today, pirated copies of the game appeared in the shady corners of the internet, posted for all the picaroons out there to download and transfer to their flashcarts.

Twenty minutes or so into the ARPG, however, many of those pirates found themselves greeted with this “Thank you for playing!!” screen and unable to progress. Players have the option of restarting the game from the last save point and playing on, but the screen reappears at random intervals. Clever!

Why not lock pirates out before even loading up the game, you ask? Well, this way, they can try out Ring of Fates, eventually reforming their criminal ways and buying it if they find the experience enjoyable. Also, anyone dumping the game for distribution wouldn’t notice this bit of programming unless they played a significant portion of it first.

Though this method isn’t 100% effective, as some brands of carts are unaffected and hackers will likely find a workaround by day’s end, it’s certainly cute! Pirates should feel thankful that this isn’t even half as malicious as Earthbound’s anti-piracy measures.

for you who wanna play this game without any “thank you screen” problem, i’d suggest use emulator, no$gba play it well, iDeas also quit good, though not as fast as no$gba (you can get full speed with no$gba).

or use this following flastcart model :
Acekard R.P.G.
CycloDS Evolution
EDGE
M3 Real
Ninjapass X9
Supercard DS One (disable patching)

NOT WORKING WITH (”Thank you for playing” screens):
DSTT
G6 Lite (Safe Mode)
M3 Perfect MiniSD
M3 Simply
R4
Supercard SD

it seem the problem occured beause rom patching, the working fashcart above (and emulator) use cleanrom to play, it it quite safe, while the other patch teh rom either before transfer the rom image to flashcart or realtime patching as you play the game (load teh rom on o DS memory). and for teh record, while R4 didn’t convert or patch teh rom on transfer, it patch teh rom when it load to DS, so for you guys using R4, that’s why

UPDATE :

User names ‘cracker’ finally made this lovely patch to remove FFCC (hugecock dump) annoying thank you screen. use the patch to patch a clean un-trimmed rom if you use a flashcart listed as not working above.
