The Atariage user mariuszw has posted his work developing Pentagram, the final game in Sabreman saga, and it is a sequel to well known Knight Lore.
He mentions that the game is being ported from the ZX Spectrum (as the images make that clear), and the most impressive thing about that is that he has developed a recompiler that takes the Z80 Assembly code and translate to the equivalent 6502! After the translation, his job is to optimize the code and fix things that the recompiler doesn’t do quite right. The recompiler even tells you where there is the need for manual intervention. Very impressive!
For those who want to try the game, he warns that “Game is slower at this moment as Spectrum version, but it is almost not optimized, so this is expected at this point. Hopefully, it can be brought to better speeds later. Game is also not much tested, so there may be some gameplay issues.”
