Two resistors in parallel always equate to a total resistance of less than the smaller value of the two resistors.
If the original resistor is 5.1k and you mount a 510k resistor in parallel, then the total resistance will be about 5050.
You cannot build up resistance by going in parallel.
You need to go in series to build up the resistance, but with smt parts you can't really do that, so your only option is to replace the resistor with a suitable value.
Since there is some question, or issue, with the paddle movement not being correct with the 510k replacement resistor, then someone should temporarily solder wires to a multi-turn potentiometer and dial in the resistance until the paddle movement matches closely to the real console and then simply measure the pot
So i installed these 430k resistors. These ones sold on ebay in america are way too small. Hardest thing i ever had to solder. So now the paddles act pretty much the same as the flashback x. About 60% of the paddle to go from left to right in kaboom. In warlords its the same as the x too and doesn’t go all the way to the right. So i will be getting bigger resistors and try to get some 10 turn 500k potentiometers to really dial in the ohms

Something else i should mention. Not sure if with all this modification stuff if the stella emulator on the flashback 9 got changed or if thats still factory but i was able to sync the atari pong blast! wireless paddles to the fb9 but they didnt work on stella with and without an sd card and all the buttons on them didn’t work in mame 2000 either. So not sure if there is a way to get them to work or not on the fb9

Thanks for this. Looks like I need to work on my soldering skills! I'll watch out for any further developments here about what resistors to use.
Whatever day my 430k resistors decide to show up, i will let you know how they work and if it goes all the way to the edge. And if they do i will change the ones on fb x too since i assume they use 510k and they dont go to the edge on one side of them.

so i found an issue with the atari arcade. retroplayer.9 and retroplayer.x both save the cfg files in 2 different locations. so all the configuring i did in retroplayer.9 did nothing when i switched back to retroplayer.x. also the ability to access the mame menu with tab was stored on the old default cfg. i gave retroplaer.x the ability to access the mame menu now too. so all of these need to be added to the atari fb 9/x only pack to make the controls work properly. fixed cfg files.zip

Agree with all of this, except that removing a smc resistor and replacing it is surely harder than adding one on top. I'm happy to experiment, but needed to know what the resistor in place was; guess I'll just have to crack the thing open and look.
In this case we cant put a resistor on top of a resistor. If it was a 510k ohm resistor and we needed to drop to 5.1k ohm we could add a resistor on top in parallel. But with a 5.1k ohm resistor already there, there isnt enough resistance. We need to add more. So the 2 resistors would have to run in series and not parallel in this case.

Actually i believe 2 diodes and removing pin wire 7 from controller board could fix the controller to work on atgames atari flashbacks

Yeah. It does not work on the Flashback X. I don't see why not if it is supposed to be wired like a regular Atari controller.
So here is why it doesn’t work on the atari flashbacks. The controllers are built into the atgames flashbacks. The joysticks and analog sticks (paddles) are just add-ons to the controllers. In modern controllers all buttons produce 3.3v that gets shorted to ground. No different in this case. So pin 9 and pin 5 also produce 3.3v. So you cant just short 3.3v to 3.3v. So pin 7 (normally 5v) is actually a second ground. So to actually make this controller work you would need 4 diodes and a little wire rearrangement inside the controller to steal 3.3v from pin 5 or 7 when in joystick mode and steal 3.3v from pin 1, 2 or 6 when in paddle mode. So in this same respect, og atari rapid fire joysticks cant cant produce rapid fire on an atari fb 3-X either without modification.
And how i first came to the conclusion before testing to prove i was right, i made joysticks that allowed 2 buttons and an adapter cable that stole joystick 2 fire and went to pin 9 on my controllers, without the adapter cable if i pressed fire button 2 on my joystick which is on pin 9 it shorted out to ground and it pops up the warning about using paddles. After that a multimeter confirmed pins 7 and 8 are both grounds.

Do those all work?? Someplace around here I have one of the joystick keychains. If atGames is really coming out with a Flashback 11, they should do a Gold/premium version with mini controllers just like that!
So some 2600 games used the b/w/color switch to do special stuff. On original fb x Some games disabled rewind and had you press select + up (which activates rewind) to activate b&w to do special stuff. This is no longer the case with the emulator swapped on the console and the usb drive. Any chance that can be re-enabled on the newer stella emulator?

My resistors arrived from Mouser yesterday. I ordered 2 different brands just for good measure and put the panasonic in the Gold model and Bourns in the standard 9 model.
They are definitely even smaller than I expected. I have very good eyesight, but they're small enough that I wouldn't attempt to do it without a magnifying glass.
My first round (on the Gold model) went really smooth. I just used a fine tip soldering iron to remove the original resistors and had no trouble putting on the new ones. The whole thing only took a few minutes.
The second round (on the standard 9) did not go so well. Although I used the same technique as before, those things just did NOT want to play nice. It took several attempts and then 2 of the solder pads lifted off, leaving nearly nothing to solder to. I then spent nearly 30 minutes trying to get the 2 troublesome resistors to stay in position and line up to the nearly microscopic sliver of plating at the edge of were the solder pads used to be. Eventually I got it to work (all 4 players), but good grief. I don't know how long that one will last. A few good temperature changes might flex the board enough to render players 1 and 3 inop, but I hope it will hold.
If you want to do this, I recommend either removing them with a hot air station. I should have done that, but after the first round went so well, I didn't expect any trouble on the second.
All that being said, I think there is probably a better resistor value we should use anyway. These 510KOhm resistors use the entire range of the paddle and seem to even be a little shy of going all the way to the left. It's not that big of a problem with Warlords or Circus Atari, but Kaboom is definitely harder to play when you have to rotate the knob all the way to the stop in both directions. Super Breakout is also harder to play this way and Street Racer doesn't go all the way to the left side of the road. Also, the emulator doesn't know what to do with paddle games it doesn't know. So, the Kaboom Deluxe hack by Darrel or the Drive homebrew don't work with paddles.
A pic of the one that went well. They're kinda hard to see in the picture because the Panasonic brand has a beige dot in the middle, making it blend in a bit with the solder in the pic:
To make games paddle compatible like kaboom deluxe you need to change its file extension to .a26x Then edit the retroplayer.ini to reflect that as well.

I've just bought an FB9 and already have an FB6 with paddles, which don't work with the FB9. Do I understand correctly that this modification (either to the paddles or the FB9) will make them work, or does this only apply to original Atari paddles?
At the moment I have the same sort of experience as Atarifatboy - pressing the fire buttons is like I'm moving a joystick left and right and pressing the rewind button, and turning the dials only brings up the error message about wireless joysticks not working properly.
Since this was never answered, atgames paddles are same as atari paddles in this situation. Need to do one of the mods.

Sorry Rom, it looks like someone determined that it is not really Bluetooth, but a more proprietary scheme. See the post here:
Im actually curious if the atgames wireless paddles used on the blasts would work on an fb9 gold? They are listed as 2.4ghz as well.

This is what I have to go from the 2609 main board to a Flashback controller, where pin one on the 2609 main board is ground.
2609mb - fbDE9
1 - 3
2 - 1
3 - 8
4 - 4
5 - 9
6 - 5
7 - 6
8 - 7
9 - 2
Edit:
What are you doing with the original controllers. Do they work okay?
My math is different here. If pin 1 on intv1 is pin 5 on intv2 it means pin 1 on intv1 is pin 9 on flashback which means the pinout for flashback controller is 925641378

Yes they work! The paddles required new potentiometers since the original ones are only 10k ohm and the atari flashback requires 1meg ohm potentiometers like the real paddles. They are smaller in size than the original and standard potentiometers

@pimpmaul69 for setting this up. It is appreciated! I know it takes a lot of time to understand the idiosyncrasies of these devices, and then to get the details dialed in.
Something you might like. Since i love modding controllers, i took some atari joystick and paddle keychain basic tv fun controllers and made mini paddles and joysticks for my flashback x.

I have been thinking about this. although I can see that the mod is more tricky, I am MUCH more attracted to using the flashback 1 7800 style controllers on my Atari flashback for 7800 games. There are also a lot of those available on ebay for cheap. I am in process of getting what I need. If there is any more "cookbook" info. you could give on making the mod, that would be helpful.
So a couple things the retroplayer.ini should be copied to your nexus slim build. You need 5 diodes that are only 1 direction. Try to find the tiny red ones like in my pic. Will make it a lot easier. I will try to get a schematic made up for how to build this atari flashback 1 mini 7800 joystick. Also the cable from flashback mini controller is unusable as it does not have all the wires needed.

Yep, that's true. They were sure not thinking about the Atari flashback constraints when they made their design choices. That said, I could look at modding the core to get the player 2 fire trick going. It's not like falling off a log. First need to see if I can build it, then see if the mod is straightforward. The mod was easy for the prosystem core, and very difficult for the a800 core. My impression on that code was 5200 two button support was put in more as an afterthought. Would it make many more games playable? I see the Lynx has more than 2 buttons anyway...
So looking at the atari lynx ii it states this:
“OPTION 1
An optional button used in some
games. Press for autofire missiles, turbo, and
so on.“so if we could add player 2 fire to use for the option 1 button it might be useful for some games

So the lynx is weird because its flippable for lefties and righties. Really 2 buttons should be all you need.

I posted a pic of the flashback 1 controller modded. I need to try to find my other one so i can try to make a better diagram of it before adding wires and diodes.

so i fixed all the controls and removed rewind for atari lynx. i swapped all select and fire controls on lynx games as they were all backwards. this completes all strictly atari stuff for the atari fb X/9. i have a build that is only atari no coleco, legends or genesis in it for strictly atari fb if you are interested

Also the lynx retroplayer.ini is missing controls for more than 25% of the games so i fixed that too.
-
So i found how to get rid of rewind for atari lynx. Global setting doesnt work. I had to create an individual setting for each game. So now my goal is to go through all the lynx games and figure out which button is best on fire and on select that wont cause issues with pressing “select” and “down” at the same time

By a long shot! Make a dot with a pencil and thats the size of these resistors.
