Dreamcast Emulation

OMG! someone help me quick cos this thing is driving me nuts. I've downloaded Chankast 0.25, nullDC and demul 0.5.5 and 0.5.6. After mounting my rom (Grandia II disc 1) which i downloaded from romulation, chankast at first told me it needs a 32-bit system to run and then it just stopped seeing the cd as a game and instead as a music cd, and it wont even play any music!!! demul 0.5.5 gives an error unable to find 'i_01d_01.bin' in romset 'dc', and i have no idea what that means. After i downloaded the MSVCP100.dll and MSVCR100.dll for nullDC, it gives the error procedure entry not found.I really just need an emulator that'll run on my system (seeing as i already went to the trouble of downloading roms) so you can go ahead and ignore all the crap before. My system runs Windows 7 and is perfectly capable of supporting a high powered emulator, witness dolphin and psx2. Thanks...

Try messing with the configuration a bit more. That may help. And I've never actually seen a DC emu working, so if it's like the real system menu, then just try loading the game through the game icon in the main menu.I don't know if it matters, but what format is the disc image in? CDi is what it usually is.

use the new version of nulldc,its the best dreamcast emulator...downlodoad it here http://www.megaupload.com/?d=YTINVEX3 ,and remember to install this aswell http://download.microsoft.com/download/5/B/C/5BC5DBB3-652D-4DCE-B14A-475AB85EEF6E/vcredist_x86.exe
