SMCoder 3.8 will launch uLE and by this means you may be able to launch ESR. other than this, no, swap magic will not recognize an ESR patched disc. cogswap works almost the same way that swap magic does, no!
cdloader?? won't comment on this one.
ESR compatibility is very widespread dude and i doubt that you will have any issues related to incompatibility. if you do run into any issues then they will be related to faulty rips, burning issues, or forgetting to patch your disc image.
most of this info is very basic and common. it won't hurt to use search feature here on the site.
