Are these games will run on the Pyra ?
I doubt. Pyra will use an ARM processor while GOG games are made to run on the usual PC platform (i686/x86-64) and the binaries use different instructions to operate.
Of course I'm not familiar with GOG at all, so please use my "answer" as a starting point to investigate yourself (does GOG offer ARM binaries?).
starwars tie fighter WILL work, the games are just packed up in a package so you don't need to overlook stuff.
The majority of my DOS games are from GOG and they're packaged in a DBP file already (not distributable of course)
Two pics with it were already added after we requested it, but thanks for watching out for us.
Send them to GOG and let them offer a Pyra version for sale
Thought about it!
A lot of my stuff has an iso which only contains the files needed to run the game from the CD and all CDDA stuff is converted to ogg! Dunno if GOG would like that.
