*Linked Capacitors/Resistors are suggestions, use whatever matches the ratings and package. **Switch is optional, and is only used with 4MB chips.
Changelog:
1.2: - Fixed missing traces
1.3: - Fixed some trace issues with Y1 - Rerouted the pcb entirely
1.4: - Fixed a short between A16 and VCC
1.4.1: - Changed AM29F016 footprint to make chip alignment easier - Cleaned up traces (visual)
1.5: - Updated kicad version from 5 to 6.0 - Redrew outline to be a closer match to original - Added markings to make cart look more original - Added switch for 2x2mb mode (this means the cart can store 2 separate roms, saves are still shared) - Changed footprint designators - Added test pads - Added date marking - Relocated alignment holes for a better fit
