The NESizer2 standalone synth from Johan Fjeldtvedt. This listing includes a cheap PSU, but if that’s not your thing, the NESizer2 can also run on a 9V battery. Audio/MIDI cables are not included. I’ll leave the custom patches and samples intact for you to use and say you made. Note: All future firmware updates (assuming there are any on the way) will have to be done by the purchaser. I’ll do what I can to help walk you through the process of installing via a Windows environment, but keep in mind you’ll likely need additional hardware until a hardware revision addresses this.
