⚠The Cartridge Reader is an open source project, that has existed for many years before launching my Kickstarter, and was created by an individual who goes by sanni.
This project represents a community-driven effort to provide an easy to build and easy to modify cartridge dumper.
We will build "version3-ALTER" cartridge reader.
Now Sanni has created "version4 & 5". You can make one like Sanni's original V3. But It's not easy to make. V4 is easier to DIY than V3. V5 of 7slots is also in development and can be created with you.
Challenges are always fun.　Happy building!
