Well you can and I just realized that interpolation doesn't affect anything having the emulator in DS or DR mode at 32 bit. If I change the resolution any higher than 512 DR or DS at 32bit, the screen becomes black. This is what it looks like at 512 DR 32 bit. Of course, everything works normal at any resolution at 16bit. Documentation didn't help at all as I wasn't sure what to look for. In summary, forget about 32bit and use 16bit.
