It's literally just a forwarder, it's not like that NSP Retroarch had that would load its own nro as opposed to loading the one in the switch directory, a forwarder saves you button presses and just loads the nro directly from the switch directory with the extra RAM so it's not like there are any self imposed downsides here like with Retroarch *almost runs out of breath*
Pretty sure mx4w knows what he's talking about considering he programmed the darn thing
