no u can`t get it chipped to play cdrs i have asked today while in town sorry
make sure there nothing in the tray
here is the hack which works on my jmb 3000
power off player then power on hold down open/close , stp ,forward skip buttons on player (not remote)
keep held down while its reading it says no disc then a menu comes up
u can now change regions 1,2,3,4,5,6 ,or region free
thats it if u get a rce disc eg world map disc change it to region 1
