(These are the known official versions of Ponymon Dawn/Dusk)
The page Version History has update information on these and other versions of Ponymon Dawn/Dusk.
I would like to release it as a patch to an original FireRed 1.1 ROM at first, but will likely make patches for other versions like LeafGreen 1.1 after filling the Ponydex #152 and on. I will include the roms.ini for PGE to see stats or tinker with the game. I will also include the modified HexEdit EBCDIC.tab to read and edit pokétext characters directly. --BlackOak42
