Missing runtime stubs for sceGsSwapDBuff and sceGsSetDefDBuff for game SCUS_97213

[roby65]

Dark Cloud 2 ( SCUS_97213 ) is missing 2 functions stubs called during initialization:

• sceGsSwapDBuff
• sceGsSetDefDBuff

[roby65]

Maybe the sceGsSwapDBuff function does not need to be stubbed and shouldn't be automatically added to the stubs list, because the functions inside are already stubbed:

void sceGsSwapDBuff(int param_1,uint param_2)
{
  sceGsPutDispEnv((param_2 & 1) * 0x28 + param_1);
  if ((param_2 & 1) == 0) {
    sceGsPutDrawEnv(param_1 + 0x50);
  }
  else {
    sceGsPutDrawEnv(param_1 + 0x140);
  }
  return;
}

Maybe the sceGsSetDefDBuff does not need too

void sceGsSetDefDBuff(undefined8 param_1,undefined2 param_2,int param_3,int param_4,
                     undefined2 param_5,undefined2 param_6,short param_7)

  iVar6 = (param_3 << 0x10) >> 0x10;
  iVar7 = (param_4 << 0x10) >> 0x10;
  sceGsSetDefDispEnv(param_1,param_2,iVar6,iVar7,0,0);
  iVar5 = (int)param_1;
  sceGsSetDefDispEnv(iVar5 + 0x28,param_2,iVar6,iVar7,0,0);
  sceGsSetDefDrawEnv(iVar5 + 0x60,param_2,iVar6,iVar7,param_5,param_6);
  sceGsSetDefDrawEnv(iVar5 + 0x150,param_2,iVar6,iVar7,param_5,param_6);
  if (param_7 != 0) {
    iVar4 = 0x800 - ((param_4 << 0x10) >> 0x11);
    iVar3 = 0x800 - ((param_3 << 0x10) >> 0x11);
    sceGsSetDefClear(iVar5 + 0xe0,param_5,iVar3,iVar4,iVar6,iVar7,0,0);
    sceGsSetDefClear(iVar5 + 0x1d0,param_5,iVar3,iVar4,iVar6,iVar7,0,0);
