wolf4sdl: game data (Spear of Destiny)

[s1eve-mcdichae1]

In the Wolfenstein 3D docs we are instructed to rename three files from the Spear of Destiny expansion from extension .sod to .sd1. (Presumably because the source files are available in both forms and so no one way is going to work in the scripts without some renaming.)

(Edit):

It seems that Steam provides the games with .sd1 files, while original installation media ("Spear of Destiny: Super CD Pack") uses .sod.

Although we can make it work with both names.

(Renaming to .sd1 broke compatibility with RetroPie-Extra's ecwolf package, but the same file runs fine when named .sod.)

wolf4sdl can run it with either name but the command is different either way. With .sd1 it needs to have the --mission 1 option, and with .sod it needs to NOT have that option.

This change checks for all three versions (sod, sd1, and the shareware sdm) before downloading shareware data, and uses the correct command for each one.

(Original):

But then the install script still checks for the old .sod file when determining whether to download the shareware version. So even if we have the registered version files, if we rename them as instructed then the shareware will still be downloaded, because the filenames don't match what is being checked for.

It still works (I'll change this from "bug" to "QOL"), it just always downloads the shareware, whether it is needed or not.

This should fix it so it will search for the correct file. I also added a function that should automatically rename the .sod files so we don't have to do it manually.

Alternatively, make it work with either name.

Renaming to .sd1 broke compatibility with RetroPie-Extra's ecwolf package.

wolf4sdl can run it with either name but the command is different (vswap.sd1 needs to have the --mission 1 option, and vswap.sod needs to NOT have that option.)

This change:

• uses the correct command for each filename,
• checks for all three versions (sod, sd1, sdm) before downloading shareware data, and
• creates the proper launch script for each version that exists.

(I can squash this if it is to be accepted.)
