Although Amstrad is the current propietary of the copyright of the original
|
|
ZX Spectrum ROMs, they have kindly given their permission for its
|
|
redistribution with Spectrum emulators.
|
|
|
|
These are the conditions put by Amstrad to use and distribute the ROM files,
|
|
extracted from
|
|
http://groups.google.com/group/comp.sys.amstrad.8bit/msg/c092cc4d4943131e

1) What exactly do you have to do to use Sinclair ROMs in an emulator, such
|
|
as acknowledgements etc?"
|
|
|
|
Amstrad are happy for emulator writers to include images of our copyrighted
|
|
code as long as the (c)opyright messages are not altered and we appreciate
|
|
it if the program/manual includes a note to the effect that "Amstrad have
|
|
kindly given their permission for the redistribution of their copyrighted
|
|
material but retain that copyright".
|
|
|
|
"2) Can you charge a shareware fee for an emulator that uses the Sinclair
|
|
ROMs?"
|
|
|
|
No. No one should be charging for the ROM code because (as a result of the
|
|
point above) there are loads of freely available images anyway. If I ever
|
|
thought someone was charging for the ROM images then I'd make them available
|
|
as a free download on the www.amstrad.com web site. Naturally I imagine that
|
|
some emulator writers want to charge a shareware fee for the code they have
|
|
written and we have absolutely no problem with that as long as they aren't,
|
|
in any sense, charging for the parts of the code that are (c)Amstrad and (c)
|
|
Sinclair.
|
|
|
|
"3) Can you modify the ROMs, for instance to enable tape loading and saving,
|
|
and if so what are the requirements?"
|
|
|
|
The ROM code is simply a tool to let the emulator writers make a program
|
|
that works as close to the original machine as possible. If they choose to
|
|
modify the behaviour in any way then that's entirely up to them (I guess you
|
|
could say that that is exactly what an emulator IS doing (ie modifying the
|
|
screen output and keyboard input to go via the PC bits)!!)
|
|
|
|
"4) Can you distribute modified ROMs?"
|
|
|
|
If you like (with that (c) proviso).
