PSR-S975 and PSR-S970 - Icon-Codes as part of files

[Runner4Fun]

Hello everyone
I own a PSR-S970 and have questions about the icon codes in the PSR-S970 and PSR-S975:

1) Are the icon codes in both keyboards identical or are there differences (number and type of icons)?
2) I am playing in a registration with a user-related style that contains an icon code (ie "Songtitle.S058.sty") in the STY file name. If the icon code is not included in the PSR-S975, does the registration of a PSR-S970 (played on a PSR-S975) find the style ?
3) Is there a list of icon codes of the PSR-S970 and the PSR-S975 available and where could I download the list ?

Thank you for clarifying answers!

In addition to the S975 these icons are available onboard.

Thank you very much, Mega Voice, for your answer.
However regarding my questions I asked the heaven is not really clearer.
I would be grateful to compare the icons between the S975 and S970 to recognize the differences between those Keyboards and if an icon on the S975 is not available (if mentioned in the names of the sty-, txt- and mid-files) what happened once used: would a RGT-file find a i.e. sty-file ?
