I'm developing a video game console and trying to figure out a way to bring cartridge games back. Partly for retro reasons but also because they have faster loading times as well as being more sturdy and reliable. The main reasoning of video games switching to cds is because they hold bigger files and is cheaper to manufacture. I know these days sd cards can hold much more then blu-ray disk. Even the modern high end video games are up to 32gb so I won't need a card bigger then that.
With that said, I'm curious if I can develop a cart that would cost $5 each compare to $1 blu-ray disk (making up random numbers). Sure the business wouldn't make as much money but I feel that quality is more important then a few extra dollars. Would it be cheaper to get a chip that holds 35gb compare to a small sd card? I'd rather have a cart that is around 4x3 inches instead of a simple sd card anyways. With older carts, they had memory built onto it. I don't know electronics that well but is it possible to use the console memory to get the data rather then having the cart memory be the main source? Smaller memory chips or none at all would help cut the cost down as well.
Thanks in advance for your help
