just science: smarphone app that simulate datarecorder.

Hi guys.

Data recorders are getting scarce, some are unreliable, and some data casettes are worn out.

Is there a app or would it be nice to have a smarphone hooked to an old device and functions like a datarecorder. an app where you can add casette images on your phone, insert into the virtual datarecorder.

it is just for science. can this be done? do we need to use phonejack to component cables and this into the MSX or C64. would this work.

if someone manage to do this, i would realy like to see a vid. Fyi there are casette player/recorder apps for IOS.

many thanks
