The problem being that I suck ass. Ok finally got round to putting DK on my M3 CF and I used the Arm7 Fix thing, followed the instructions but it won't work! Then I tried DSlazy and did all that, I got the title screen and then black screens. Did the same with Juiced 2 as that game crashes a just before you start a race. I must be doing something wrong right? Usually I get my roms pre-patched so I've only started using the arm7 fix today.
