  1. None of the above. The 2600 has a very simple hardware and almost everything is handled via software. The polling rate of the joystick and how the game reacts to a button press is determined by the code in the cartridge itself, and what you experienced is exactly how that particular game is supposed to behave, as you can see by reading the manual linked by @CapitanClassic:
  2. I'm not familiar with batari Basic, but the symptoms you're describing (genesis C button always detected as pressed) happen if you have bit 7 of VBLANK set. That bit is used to discharge the paddle capacitors and while it's set, bit 7 of INPT0 to INPT3 will read as "0".

  4. The portable uses a (quite inaccurate) proprietary emulator that probably only supports bankswitching schemes used in original games. So it's unlikely that the game will ever work there. The FB9 uses a very outdated version of Stella (3.x), but should in theory support the bankswitching scheme used by CC (Superbanking), as it was added in Stella 2.5. If it doesn't work then maybe the autodetection fails or the game crashes because of some bugs in the emulator (that old version lacks the accurate TIA core of the current Stella).
  5. The pixel's aspect ratio of a NTSC Atari 2600 differs from the one of a PAL console and none of them match the square pixels used by computer displays. So there's a bit of interpolation going on to keep the image aspect ratio the same as you'd get from real hardware. There are tons of settings you can change in the "Video & Audio" menu, including the ability to disable aspect ratio correction. Check the manual.
  6. It can't run on a standard Harmony cart, only on the Encore. And you need to use the firmware posted here: https://atariage.com/forums/topic/318521-harmony-encore-circus-convoy/?do=findComment&comment=4782378
  7. No, because it wouldn't serve any purpose. None of the existing games would use the extra ram, and a developer programming a game for such a modified unit would reduce the potential user base down to about 5 people (worldwide). Developers who need additional resources add extra hardware into the cartridge itself, so that the game will work on any 2600 console.
  8. I have two early Italian manuals (combat and basketball), with the "Melchioni" brand (The early italian distributor of the Atari VCS, from 1981 to 1983). Here are the scans if anyone is interested: basketball_it.zipcombat_it.zip
  9. I think that if you flash the game as an "offline rom" using the SMT32CubeProgrammer, you bypass the PlusStore completely. This requires creating a TAR archive of the rom, installing the STM32CubeProgrammer software and also opening the Cart to access the micro usb port, though. So it's not very user-friendly as using the PlusStore, but avoids sending the rom over the internet.
  10. Why should we care about the general gaming community? One of the best thing about this community is that is a small group of people that likes to play, collect or program new games for a 40 years old console the general public don't care about. And because of this the only motivation is that we have fun in doing it. I like to live in a world where most people don't even know what an "Atari VCS" is...
  11. You need Paddle controllers to play that game on real hardware. Set the left difficulty switch to position "B". See the manual.
  12. In addition to that, I'd also like using one of the console toggle switches to change the direction in which SELECT scrolls the menu entries, as proposed by @Al_Nafuur here.
  13. Sure, hopefully it would be needed only in very rare cases. But it's good to have the option IMO.
  14. Technically they have it, although you have to flip over the console to reach it, so it is basically unusable...😄 Whatever switch combination is decided, I think a way to disable the exit function should also be added. There's always the possibility that some rom interferes with it, no matter what. Ideally, a way to disable it per-rom would be great (e.g. using a special extension in the filename), but I don't know if this is feasible.
  15. This thread made me want to dig out my videoplay to see if it still works after a few years in storage... It does! I took a few pictures. you can see the rivets on the joysticks, and the a/v cables (the unit is modded for composite) Note that the lid on the joysticks compartment was missing, so I built one myself using a sheet of black plastic. Not perfect, but it does the job.
  16. Thanks for sharing, very interesting! Too bad you couldn't fix it. I bought a Saba Videoplay years ago and while it is currently packet away, I have a few pics on my PC. The power switch was stuck on mine too, I remember I fixed it by spraying a lot of WD40, and let it act overnight. My controller were in worse shape than yours as, in addition to broken wires and plastic pins (I used epoxy for those), the plastic that holds the base of the shaft was broken, so I had to get creative and I modified a metal bracket, and fixed it with a couple of small rivets to replace it. I don't have a pic of the reassembled controllers, but they came out not too bad, and more importantly, they work. I confirm that mine has the same factory modifications (resistors soldered underneath the pcb, and the small daughterboard near the RF modulator). The pcb is the same as the original Channel F, and also the rf shielding, the buttons and the entire cartridge port assembly, and in previous versions there was a speaker mounted where that big circular hole is, on the front right side of the console. The modification is for getting the audio out of the RF modulator instead. You can also see the pads where the original power switch of the Channel F would go on the rear of the console.
  17. Out of curiosity, could you take a pic of that "Aardvark" game running?

    I'm not familiar with the "new" VCS, but I think the controllers use bluetooth, and that wouldn't work. The 2600-daptor should work, but I don't have a R77, so wait for confirmation by someone who actually owns it.

    That's the same for most people, and that's why many are fooled by the false advertising on the R77 web page: "It plays your favorite 2600 cartridges". If you know "how it does it", you also know in advance why it won't always work and why it never will, so I think it's worth stressing the point. Software emulation can offer a lot of advantages over real hardware, but one thing that cannot do is playing cartridges. No controversy, it's just how it works.
  20. Seems to be using the "Menu Driven Mega Cart" design:

    If you plug an OTG cable on the micro usb input on the back of the console you can use any existing usb (non bluetooth) wireless controller.

    That is not correct. the Retron 77 doesn't play ANY cartridge AT ALL. It never did and never will. This was clearly explained in the first posts of this same thread, back in 2017, a full year before the release of the device. The Retron 77 only plays roms. The cart port is just a gimmick that tries to dump the rom from the cartridge and then feeds it to Stella. This might give the illusion of running the game from the cart, but it's not what is really going on. You're still playing a rom of the game, while the rest of the hardware on the cartridge (ram, bankswitching logic, coprocessors, etc.), is emulated in Stella. Even with a good cart dumper (and the Retron 77 one is by far not a good one, often failing even in the simple task of detecting the presence of the cartridge in the slot), this trick cannot work for all carts. And both the dumper software and the emulator need to be continually updated as new bankswitching schemes are developed. A real Atari 2600 doesn't dump the rom from the cart. The Flashback 9 uses Stella 3.x series, which is ancient by now and lacks the new TIA and sound emulation and the other countless improvements that Stella had in the last several years. The current Stella is extremely accurate, and if you fire up a rom you can be 99.9% sure that what you're seeing on the screen is what you would see on real hardware. In fact I don't think I've seen any bug about inaccuracy of TIA emulation reported in the last couple of years.
  23. It would happen with a Sears Video Arcade II or Coleco Gemini controller, as they only have one paddle pot on INPT0/INPT2. (But there wouldn't be much point in using them with this game, as the fire buttons are wired to pin 6 - INPT4/INPT5 ) and likely with the Hyperkin Ranger too. And can also happen with a broken paddle set (broken pot or cable).
  24. Ok, now print the logo with a translucent filament, put an RGB led inside wired to 3 unused GPIO pins and make it software programmable.
