Well, that we today play this game both with and without drops is only out of ignorance. At the time this game was invented the rules were of course known, and nothing would have been optional about them. So it would either have been one or the other always. Based on the power of the pieces I am now convinced that the original rules would have included piece drops. And with piece drops there is no such thing as (meta-)color binding; any piece can get captured, and re-appear on any color it wants. Also note that the Heavenly Horse is a promoted piece. Because of the promotion zone being 3 ranks deep and the way the Liberated Horse moves you can promote on 3 of the 4 possible meta-colors.

The power of the pieces doesn't mean much. Look at the larger variants or even Sho Shogi which is just regular Shogi with a drunk elephant and no drops. Weak pieces doesn't and didn't necessarily imply that drops were used. 

When I try to promote a Flying Falcon, it promotes to a Tokin instead of a Tenacious Falcon. However, this can be easily fixed by making the King the last piece and changing the parameters accordingly.

Ughh, this was a case of a >= that should have been a > in the Diagram script. The algorithm is that the promoOffset is added to promotable pieces (all types from 1 up to and including maxPromote) to get the promoted type. When this gets larger than the number of defined pieces, it is replaced by the promoted type of the first piece. The latter was introduced to not explicitly have to define all the Golds that result from promotion of a host of different Maka Dai Dai Shogi or Thai Shogi pieces; if the first piece is a Pawn, and promotes to Tokin, all pieces that also promote to Tokin can then be put last amongst the set of promotable pieces. After that can follow the unpromotable pieces, and then all the promoted types that are explicitly defined. So if (say) maxPromote=10, and promoOffset=15, piece 1 will promote to piece 16, pieces 11-15 will be unpromotable. Piece 16 and higher are the promoted types. But if only six are defined (16-21), these will be the promoted versions of 1-6, and 7-10 will all promote the same as 1, to 16.

I fixed it now, thanks for reporting.

They all appear to be from the same directory.

I now created the tiles piece set for Wa Shogi, as 99x99 PNG images of two-kanji tiles. (The Interactive Diagram displays those at 33x33, but they can be zoomed in on to improve the resolution, rather than blur them.) Although Wa Shogi has many pieces that also occur in other Shogi variants, the names are all different, so there is no overlap with the tile sets for other Shogi variants.

From what I gather, several sources exist, with different movesets. As I don't read japanese, is there anyone who knows what the other movesets are, and how credible they are as sources for Wa?

I am not aware of any such sources.

Shogi Zushiki, sho Shogi Zushiki & Kokon Shogi Zui are given by Cazaux as sources.

I do not have access to These, nor anything relating their differences on wa/yamato.
