I use some isopropyl alcohol or deoxit on the contacts and try to clean them by scraping them slightly with a small and thin flat screwdriver. Sometimes inserting, removing and reinserting the cartridge a few times does the trick. Worse case, the rom chip in the cartridge is bad (it’s rare but happens) and there’s little you can do to fix ...

This project makes it possible to load Atari 2600 and 7800 roms to the 2600+ using an USB to serial cable or module and a Python script. Modifications to the Atari 2600+ mainboard and I/O board are required and void your waranty.
Normally the Atari 2600+ dumper analizes the inserted cartridge and when it has detected the cart type, the dumper pulls the CAR_TEST pin high to tell the mainboard that a cartridge is detected and then sends the romdump over the serial link.
The 2600+ loader takes over the dumpers job but in order to do this the connection of the CAR_TEST and TX signals between the I/O board and mainboard must be severed. With mod v1 a switch is added to allow switching between normal 2600+ functionality and the loader mode. A future mod v2 will do the switching automatically.
To sever the connection of the CARD_TEST and two TX pins between the I/O board and mainboard, the pins can be cut off (the easy method) or pushed down into the header while heating up their respective solder pads (recommended method).
The loader tool is a python script. To run it, open a commandline window. When no Python is installed on your computer (or you don't know) enter:
or when Python is installed with pySerial on your computer, you can run the script directly by entering:
comport is the name of the serial port of the USB serial cable/m,odule. To find out which serial port is used, go to device manager and check under ports which com port is added when you connect the cable to the computer.
romfile is the filename of the Atari 2600 or 7800 romfile. For Atari 2600, the rom size must be 2K, 4K, 8K, 16K, 32K and 64K any other size is not supported (2600+ firmware v1.00). For Atari 7800 roms, the romsize may vary as long as the rom has a 128 byte header with the correct romsize.
For this mod an USB to serial cable or USB to serial module and a mechanical (DPDT) switch are needed.
The USB to Serial cable or module needs to have at least GND, RX, TX and RTS signals available. For the switch you need a DPDT switch meaning a switch with 2 rows of 3 contacts and that can be put in two positions.
Wires are soldered from the severed connections of both the I/O board and mainboard to the switch. The TX and RTS signals of the USB serial cable/module are also soldered tothe switch.

Nov 15, 2023 · The 2600+ is smaller than the original hardware, but the cartridge slot is the same size, meaning it can still play games released for the original VCS/2600 in the ’70s and ’80s. Set the console up and turn it on, and you’ll get the Atari logo then… nothing. No front-end, no menu screen, just a message saying there’s no cartridge ...
