Ok Im back --- 

Playing around with a bunch of games.

Most games just needed one button, like Donkey Kong and DKJR etc ...

How about the second button for Astroids? where do i program that?


Screen shot would be greatly appreciated

The Atari of the time only used a joystick with one button.   Asteroids only used one.  https://www.atarimania.com/8bit/files/Asteroids_manual.pdf

As noted above, OPTION = F4

Just wanted to thank you for all your responses and help you have been great! 

but hitting F4 doesn't seem to do anything for options on difficulty - but I am in a good spot here - and again wanted to say thank you for getting me up and running.

I am going to stop here, and just play harder haha -

Thanks pal -

When i hit F4 what should happen?

Does a menu show up?

When playing DK and hitting F4 - the game just starts.

Is there some kind of menu that should be showing up? 

Or does the game itself do anything? 

Sorry i know i said i was good here - but just curious

I will leave you alone if you dont know

For this particular game there is no menu. It simply toggles the difficulty each time you hit F4 to one of the 5 difficulty settings.  The icon in middle changes each time you change settings.   Manuals are located here https://www.atarimania.com/game-atari-400-800-xl-xe-donkey-kong_1673.html  As to what each of the difficulty settings changes/does as far as game play, have no idea.

I'm Back!!! haha 

Hey pal thank you very much everything is working great and cant thank you enough!

Another question, not sure if you can help me or direct me somewhere.

When i play Donkey Kong i never run out of lives. Which is kind of cool and has helped me get to the cement factory! The DK Dream!

From my research this is called a "cheat". 

However no other games in the Atari 8 inventory does that happen to.

Is the cheat part of the ROM? 

Any idea ?

I would like to apply that cheat to other games like DK JR and others. 

Any help would be greatly appreciated. 

I also heard there are cheats where you are invincible and cant be hurt but thats not what i want- that would totally get rid of why play the game.

Just looking for unlimited lives 

Any of this make sense?

Altirra has a cheat system.  It is listed in main menu under "cheat".  You can either enter in the hex codes manually or load them from files others have made.  Altirra can use Atari800 emulator cheat files or ones specific to Altirra. You can google around to find them. I don't use them but as example here is cheat file for Donkey Kong Jr. that gives infinite lives  DonkeyKongJunior.a8t 

Select the Cheat menu, select Load and go to file. Then hit the double arrow button to move into Cheats window.  If checked then active.  Sometimes warm reset needed. You have to have the exact same disk/cart file that was made for the cheat file or likely won't work (or crashes game/causes other odd things).  The cheat is altering the code of the game.  Remember to uncheck the cheat (or delete) when going to another game or will cause issues.  You also won't always get a cheat that is like you want as depends on how the code can be altered.  Also not all games have cheats unless you are into hex editing and understand the game code to know where to alter.

So I know this discussion is a bit old, but if anyone is still following this...
 

I'm trying to use the Atari800 emulator on my Anbernic RG503.
 

It loads the game ok, but it won't make save states through Retroarch. I'm trying to make a save state in the emulator itself.
 

I can select a directory for a save state, but I can't figure out how to get it to actually save.
 

I'm also trying to figure out the disk system. I see where I can add disks. I need to swap in a blank disk to save my game, but I can seem to figure out how to do it.

Any tips would be most appreciated.
