I think I've worked out where the problem is. It was another part of
code, relating to the workspace, and I must have worked the pointers
out wrong, and I can't work out how to fix it, so I'm going to need
some help here. Below I'm going to paste in all the relevant bits of
code (structs and functions).

/*---------------------Code starts here--------------------------*/
typedef struct
{
 int RUNNING, SCREEN;
 int scrnW, scrnH;
 GsOT ot[2];
 GsOT_TAG *otTag;
 long otLength;
 int ab;
 PACKET *gpuPacket[2];
 int tvMode;
 int red, green, blue;
} rpGAMEINFO;

void rpInitGameStruct(rpGAMEINFO *game, int RUNNING, int scrnW,
      int scrnH, long otLength, long maxPackets, int tvMode, int red,
      int green, int blue)
{
 game->RUNNING = RUNNING;
 game->scrnW = scrnW;
 game->scrnH = scrnH;
 game->otLength = otLength;
 game->otTag = (GsOT_TAG
*)malloc(sizeof(GsOT_TAG)*2*(1<<(game->otLength)));
 game->gpuPacket[0] = (PACKET *)malloc(sizeof(PACKET)*maxPackets);
 game->gpuPacket[1] = (PACKET *)malloc(sizeof(PACKET)*maxPackets);
 game->tvMode = tvMode;
 game->red = red;
 game->green = green;
 game->blue = blue;
}

void rpGraphicsLoopStart(int *ab, PACKET *gpuPacket, GsOT *ot)
{
 *ab = GsGetActiveBuff();
 GsSetWorkBase((PACKET *)gpuPacket[*ab]);
 GsClearOt(0, 0, &ot[*ab]);
}
/*---------------------Code ends here--------------------------*/

If I create:
rpGAMEINFO thisGame;

and initialise it using:
rpInitGameStruct(&thisGame, 1, 320, 256, 1, 48000, MODE_PAL, 0, 0, 0);

what do I pass to rpGraphics LoopStart for the 2nd argument?

I was passing thisGame.gpuPacket[0], but I've established that this is
where the problem is. Can anyone work out (and possibly explain) what
I need to pass to the function, please?

Thanks a lot to everyone for their past and hopefully future help :-)

Cheers,
Rikki
