  We give an update on the ongoing effort of the RC$^\star$ collaboration to
generate fully dynamical QCD+QED configurations with C$^\star$ boundary
conditions using the openQ$^\star$D code. The simulations are tuned to the
U-symmetric point ($m_d=m_s$) with pions at $m_{\pi^\pm}\approx 400$ MeV. The
splitting of the light mesons is used as one of three tuning observables and
fixed to $m_{K^0} - m_{K^\pm} \approx 5$ MeV and $m_{K^0} - m_{K^\pm} \approx
25$ MeV on ensembles with renormalized electromagnetic coupling
$\alpha_\mathrm{R} \approx \alpha_\mathrm{phys.}$ and $\alpha_\mathrm{R}\approx
5.5 \alpha_\mathrm{phys.}$ respectively. We will discuss some details
concerning our tuning strategy and present the calculation of the meson and
baryon masses. Finally, we will also present a cost analysis for our
simulations. More technical details on finite-volume effects and the tuning can
be found in A. Cotellucci's proceedings.
