Use the Spectrum 128 style menu below to navigate to the various sections concerning the ROM disassemblies.
Amstrad released three different language versions of the Spectrum +2 - English, Spanish and French. These differed only in the text displayed in the menus and error messages.
However, no attempt to maintain ROM routine entry points was made and so programs that directly access the ROM, e.g. Hisoft 128 BASIC Compiler, will fail on
the non-English language versions.
The Spectrum +2 ROM is very similar to the
Spectrum 128 ROM, introducing no new functionality or bug fixes. It differs in the following ways:
- The copyright message was changed from ©1986 Sinclair Research Ltd to ©1986, ©1982 Amstrad Consumer Electronics plc.
- The Tape Tester menu option and routine were removed.
- The Tape Loader message was supplemented with the message Insert tape and press PLAY.
- ROM routine entry addresses were shifted due to the above changes.
The following table shows a comparison of the different language versions of the Spectrum +2 ROM and the Spectrum 128.
| Spectrum 128 | Spectrum +2 | Spanish
Spectrum +2 | French

The three language versions of the Spectrum +2 ROM 0 disassembly were automatically derived from the Spectrum 128 ROM 0 disassembly using
a Windows conversion utility I produced.
As updates to the Spectrum 128 ROM 0 disassembly are made, this utilty should always be used to create the equivalent Spectrum +2 listings
and hence to guarantee that all versions remain in synchonisation.
