It wouldn't sell so well if they delayed until April or whatever to fix issues. Get the hardware out, fix with firmware updates. You see the same thing in the games industry. They ship games in a broken state to meet a crucial deadline and fix with patches after release. 4 Quote Link to comment Share on other sites More sharing options...

So you can use original controllers hooked to the 2600+ as a USB controller to play games with Stella on your PC (Joystick port 2 must be configured in Stella to work) This works on MiSTer, too. Doesn't recognize the Select/Reset switches, though, which is a pity. This would make a very nice control box for the MiSTer 7800 core. Now if your dumper code could be launched as a MiSTer script... well, there's the cartridge port everyone has been asking for. Quote Link to comment Share on other sites More sharing options...

Are the B/W and difficulty switches recognized on MiSTer? If not, do we know what USB codes the switches are sending that could perhaps be mapped in the core? (Because it would make for a hugely expensive joystick adapter, but providing the original experience enough to make it absolutely compelling.)

I can't see that any of the other switches are recognized. I'm no hacker, though, so a more enterprising person could probably figure things out.

The Select, Reset and difficulty switches seem to be only available to the rock chip. However if you wish to hook the 2600+ to the MiSTer then you could remove the main board and hook al the IO to the MiSTer. 3 hours ago, xeex said: Now if your dumper code could be launched as a MiSTer script.. Don't know about MiSTer scripts but the Python code is easy modifyable. If the MiSTer script contents can be passed as a command line then you don't even need to modify the script. 1 Quote Link to comment Share on other sites More sharing options...

Spanner Posted November 29, 2023 Share Posted November 29, 2023 (edited) The USB port on the PCB with the Rockchip and nand, thats not a USB-C is it, well it does not look like one, it looks like a Micro USB port so you should be able to put a OTG Cable on it or a USB Hub with a Micro USB connector on it and maybe have its cable coming out of the Atari2600+. To connect a USBserial to the Atari2600+ UART(thats what the 4 header pins are called) you can connect it using a rubber band so you do not need to solder the pins on, thats how I have my cables connected. You can use 2 wires connected to the TX, RX and ground it by its HDMI cable thats connected to the PC.

Thomas Jentzsch Posted November 29, 2023 Share Posted November 29, 2023 For the record, I just tried the OTG-cable from my R77 and connected it to the internal USB port. But my controller connected via USB did not work. Quote Link to comment Share on other sites More sharing options...

Maybe it works cause it only has a single power profile (5V/3A) or it's just a 5V/3A power supply with a USB-C plug. Anyway if a smartphone (fast) charger or a power supply with a USB-C connector or cable doesn't work and you wonder why it doesn't. It's because the USB-C on the 2600+ isn't fully compliant with the USB-C standard. 6 hours ago, Spanner said: I just opened mine and it has no big yellow resistor on the right hand side Interesting.

Blinky Posted December 2, 2023 Author Share Posted December 2, 2023 Discovered the function of the CAR_TEST (CARD_TEST on the main board) pin. This pin is controlled by the dumper MCU to signal the mainboard that a cart is inserted in the slot. When there is no cart in the cart slot this pin is low. When a cart is inserted it is set to high and remains high until the cart is removed or a dip switch on the cart is changed. In case a dip switch is changed the pin goes momentary low and then high again (probably as soon as it detected the new game rom) Quote Link to comment Share on other sites More sharing options...
