So I was puting away my 2600 when an idea hit me, what if there was an advanced passthrough cartridge almost like the sega 32x. Here's a list of features it could include.
-Built in bios
-Extra 64k ram
-Cartridge pull out protector (If you pull out a cartridge, it will reboot to the bois)
-Sid chip (so we can finally have better music in our games)
-Dpc+ and Superchip compatible
I would love to do this myself but I'm not very good with electronics nor do I have the budget to do it. XD
