Shark released it but haven't seen a tool with it yet.
Credit for this goes to Shark.
C#
int Param1 = PS3.ReadInt(0x832524);
Cbuf_AddText(0, "cmd mr " + Param1 + " -1 endround;");
C++
char buffer[0x100];
Sprintf(buffer, "cmd mr %i %i %s", *(int*)(0x832524), -1, "endround");
Cbuf_AddText(0, buffer);
