/vr/ - Retro Games

Personally, I enjoy collecting them, though I use them mostly for fucking around.
The one on the right for the Famicom for example has an underclock feature, can backup savegames and can do ROM and RAM modifying codes which is pretty neat.

Just received the cart on the left today.
They're pretty both pretty cool cheat devices. Left is from 2005 and runs through a CPLD and right is from 2003 and runs through an fpga.
Thanks to the time they were released in, they have flash memory which allows saving cheats.
Left one also has a SRAM backup feature, a downclock feature and is the only device for the NES/Famicom to use RAM-modifying cheats (in addition to ROM modifying cheats)
Pretty crazy to think that the famicom was still popular enough in 2005 in Japan for a company to actually still produce something for the console.
