Hacking Help with Grand Slam Tennis

[ghuk]

Hi all

Need some help, cant get Grand Slam Tennis to run via my USB loader GX. Keep on getting an error message when I load it up saying to eject the disc turn off the machine and consult the manual

After reading some of the other posts on here I have tried forcing NTSC but that just causes the screen to go completely black and nothing happens at all. The USB loader is compltely up to date so I know its not that and I have never had any other issues with my other games either

Any advice would be much appreciated

Cheers
