If it's really compatible with 2600 carts, SD card carts already exist and work great!

Personally I've found 2600 carts to be pretty durable. Almost all of the carts I bought new still work, and I still use them frequently!

They have a list published; it’s compatible with some, but not all, cartridges. It’s a Rockchip-based system, not an FPGA like Analogue’s stuff; my guess is this will work like the Hyperkin RetroN. Those systems dump the ROM off of the cartridge and then start an emulator it, which doesn’t work with SD card carts - the emulated ROM loads but can’t find the SD card because the emulator doesn’t actually talk to the cartridge hardware directly.
