Other solution of the "patch doesn't match" (good rhyme xD) problem could have been to upload the original Pokemon Red Version (or earlier expanded rom) so everyone will have fast access to the nice game (maybe some will try another game when they don't find the right original^^) maybe you could upload the original version in your main entree for us ^^ (i got a link to an expanded file, so i also have to look where the unexpanded version is^^, or instead of upload just a link to the correct rom^^)
To the game:
1. found out how to play it in mobile^^ i patched the rom on laptop then transfered it via google drive to my mobile phone, downloaded John GBA Lite Emulator and now i can enjoy the game during work xD
2. i thought about the starter issue (some don't want to face them in the very beginning) - also pokemon like riolu or larvitar or pikachu^^ ->
my ideas:
A: Pikachu and the other better pokemon could be found rarely in the routes after vertania, same for the starter pokemon where you have grass water and fire in different areas, f.e. grass in vertania forest, fire in rock cave, and water by fishing or near by a sea.
B: First generation like normal in story, second generation could include an event, maybe a new small arena where you're tested against the second generation (an old man who just have the three pokemon and want to give you one of them, when you defeat him after catching around 20 different pokemon of kanto dex, third generation could be an emergency of an assistent, who is attacked by a zigzagoon like in emerald, and he wants you to help him with one of his three pokemon, which you'll get then after winning. (when holding 6 pkmn, sending.to pc) The 4th generation could be wild pokemon (rarely in different regions in late game) or also events in past regions after defeating champ. The other pokemon of the three generatioms could be claimed after a special goal (maybe first generation after top 4, 2nd and 3rd generation after a later goal during past story. But you have to battle them or help them out with something to get the pokemon (maybe showing the old man a trained Gyarados for fulfilling his dream, etc)
