things to try:

• skip add on the top-byte multiply in sqr8/mul8

  • should save a few cycles, suggestion by jamey

• patch the entire expanded-ram imul8xe on top of imul8 to avoid the 3-cycle thunk penalty :D

• y-axis mirror optimization

• extract viewport for display & re-input via keyboard

• fujinet screenshot/viewport uploader
