Good morning all,

I would like to warmly thank Hap, Fhub and all the contributors to this incredible and magnificent project as this “Mess Chess Emulator”!

It is simply amazing to be able to play with machines that I dreamed of at the time and that I could not have ...


A special mention also to the SchachComputer.info site which allows us to follow this exciting adventure among so many others!

For years, I have only been a passive reader of this encyclopedic site dedicated to our passion for these electronic chess computers, I have no time to contribute, Alas ...

However, I have two questions regarding 2 emulated machines:

- 1 / I have two original Fidelity Sensory Champion (a German version and an English version), and their opening libraries are strictly identical but the version emulated in CB-Emu has many disparities in the openings, for example:

1/ e4-e6
2/ d4/d5
3/ Nc3-Bb4
4/ e5-b6 (CB emu does not know b6 but knows c5)
5/ a3-Bxc3+
6/ bxc3 (end of the book of my two original Sensory Champion)
ou encore:
1/ e4-e5
2/ Nf3-Nc6
3/ d4-exd4
4/ c3-dxc3 (CB emu does not know c3 but knows Cxd4)
5/ Bc4-Nf6
6/ Nc3-Bb4 (end of the book of my two original Sensory Champion)

There are many more examples.
While researching, I discovered that the book of the Sensory Champion of CB emu seems to correspond to the book of the Sensory Voice.
My question: Have there been two successive different versions of the Fidelity Sensory Champion's book?

- 2 / I don't have a Fidelity Sensory Elite (Alas ...) but by testing the emulated version, I realized that the opening library does not correspond to the original commercial model.

By pushing my research a bit, I realize that his library seems to correspond to the Travenmude model. For example, on the Sicilian opening, after 1: e4-c5, the Travenmude model with his special book "World Championship 81" only played 2: c3. The emulated version also only plays 2: c3 also unlike the commercial version which could play 2: Nf3. So this emulated version would be the version of Travenmude? But it worked at 5 Mhz and not 4 Mhz…

Thank you very much to the specialists for enlightening me on these two points.

All the best to all!
