  return (
    <>
      <select value={selectedBoard} onChange={(e) => setSelectedBoard(e.target.value)}>
        {boards.map((b) => <option key={b.id} value={b.id}>{b.name}</option>)}
      </select>
      <button onClick={async () => {
        const bytes = new Uint8Array(await (await fetch("/demo.elf")).arrayBuffer());
        loadProgram(bytes, "elf");
      }}>Run</button>
      <VemuCanvas hasVideo={hasVideo} setDraw={setDraw} />
      <VemuTerminal setUartSink={setUartSink} sendUart={sendUart} />
