Backup imports...?

I thought import games could be played useing the swap method, but when I play backups of imports (like Sailor Moon VE from Lockcole's FTP) it doesn't work out. I converted the image with satconv, and that helps it load the sega liscencing screen, then everything goes black and the cd stops accessing. Anyone know what's going on? Oh yah, and I thought the AR4M+ was supposed to enable swapless backup playing (so says where my friend bought his), but it doesn't seem to do so. If anyone can help, it'd be much appreciated. Thanx.
no cart allows you to play backups, period.

ONLY the modboard will let you play them without swap.

Well I know in Chinese stores you can get a "Super Magic Strong card" or "Speed SW" swap card which Aids in swapping and timing by pretty much doing alot of it for you, but nothing that does it automaticly.
the AR4M+ should allow playing of imports anyway, so you shouldnt need to mess with pathcing the iso

it possible the cart isnt 100% working, do you get the bios screen of the cart (the one with action replay at the top)
