Thanks for the answer, I understand .. so it's not that simple, it's a real shame because for me only a small part of homebrews work properly.
In this regard I would like to point out that this thing is a little annoying, I understand that Atari is an American brand and that therefore it is there that most of the fans are, but it would be right that when someone makes a game make sure to also release the pal 60 and pal 50 versions, if I were able to program a game I would do it to make sure anyone from anywhere in the world can enjoy it.
As it stands now it gives an impression of the type ''who cares about the rest of the world'' So if any of the homebrew developers read this message please also make these versions for your new or old software.
This is not meant to be a negative criticism, indeed I thank all those who still do their utmost to keep this fantastic console alive, in many cases these software are even superior to most of the original titles.
Some examples that I have been able to play and that still amuse me so much: Amoeba jump, Blinky, Chetiry, Climber 5, Fall down, Crazy balloon, Go fish !, Ixion, Jsumo, LEM, Pac-man 4k, Pitkat (I have the original for Gameboy and seeing such a faithful conversion running on the Atari 2600 is incredible), they are all little masterpieces.
Unfortunately many others that I would love to play do not work properly: Bird and beans (mythical pyoro from Warioware games), Eggventure, Gingerbread man, Jammed, Palomino, Juno1, Lead 8k, Monkey king, Peril, Ninjish guy, Princess rescue, Seaweed assault, Slideboy , Thrust, Snow flakes, Shower scene, Rc sumobots.
I've seen gameplay of these on youtube and they all look really fun, unfortunately I've tried all the various releases and versions that I have found but none work for me, I would love to be able to play them so if anyone has the pal 50 versions or can convert them for me (and for everyone else who has the same problem as me) , I would be infinitely grateful.
