ok so i have a TTDS and i got chinatown wars and it didn't work on my card. I got the rom from a random download site because i needed it fast, and it came with all of these external files and un needed stuff, so i deleted everything but the rom itself. i tried the rom and it had the same problem everyone else's has had where it freezes after you start a new game. so I heard of ways to fix and and tried them, i got the new firmware update for TTDS (1.17) i put it on my ds, and chinatown wars still didn't work (i replaced the old menu files,ect, with the new ones) I also read about putting the cheat database (.DAT file) with the menu files as i was told too, and put the cheat database for chinatown wars (.ARP file) with the chinatown wars rom. after i did this Grand theft auto: chinatown wars worked! the next time i played it i realised my TTDS froze upon startup, but after a couple tries it would work again, then a few days later it wouldn't start at all becaue it kept freezing. so i took all of the files I put on, off of my ds card, except for the firmware update because i deleted the old files and my card doesn't work without them. and my TTDS card still won't work... soo.... what i'm asking is; "Is this a common problem? how can i fix it? and what's wrong?" Thankyou in advance and i apologize if this question has already been answered and I'm asking about something easy to fix.
