Christoph will not include the ROM code with his emulator. It is copyrighted material, and has not been released to the public domain by HP. If you dig around Erik's web site, you will find that he has made some contacts at HP in an effort to secure its release. Given the size of HP, the odds of anyone within the company taking the time to consider this, run it by legal, etc., just to help out people who might otherwise buy a 33S or 48gii/49g+ (in their mind, it is just a calculator, after all) would seem to be slim (in my opinion.)
So Christoph’s product will require you to provide your own Rom. How you come by the Rom is your business. I think he (and Hrastprogrammer, for his 42X emulator) works under the assumption that if you have a 42S, you can extract and use the Rom. From a legal perspective, I think there is some question regarding whether you are actually allowed to use the Rom any other way than how you bought it, i.e. inside a 42S. I am certainly no lawyer, so this may not be true. Either way, from Christoph's perspective, that is your problem, not his.
Regarding inclusion of all of the calculators, I believe the emulator will “become” any of the supported calculators for which you have the required Rom. So for each of the emulated calculators, you will need a separate Rom image. I’m not sure of the details, but I believe to get a particular calculator, you need to place its Rom image in the proper folder, then start the emulator. It then uses the image it finds in the place it automatically looks. So if you can get Rom images for all of the calculators, the emulator will emulate them all.
The above information represents my interpretation of the information I have gathered on this issue. I have no special connection or association with Christoph or Erik, and apologize to both if I misstated anything. I may have one or more major or minor details wrong, and invite Erik to correct as needed.
