WHAT'S HAPPENING??
 

When i try to boot Gallop Racer 2001 (usa) using ar2 (neo2.2) at the action replay swap point the screen never gets past the 'loading' point. This also seems to happen on another usa backup ive got !! Any ideas peeps?? Ta.

PS. Normally I just press 'x' to load on action replay , have heard of pressing r1 and circle together, any ideas what this is meant to acheive diff. to other method?
