Line connectionsДЇrom the perspective of the cartridge, some pins are floating and require a pull up/down resistor to enforce a known state, in this case, 10K Ohm resistors were used. It is helpful to use the Cartridge breakout board as a reference by connecting it to the reader, which allows to probe and identify the lines (as the breakout board has correct labeling). Note: The Cartridge reader has incorrect labeling of the pins.

This makes for 24 of the 32 lines to the cartridge. Meaning that there are 16 connections exclusively dedicated as inputs (address pins) and 8 connections as outputs (data pins). The GameBoy Cartridge is effectively implemented as a parallel bus. Therefore, sometimes it is preferable to do it with simple hardware that one might have at hand or that is simple to get online (See the hardware list above). While there are cart readers you might get from an online store, it might take a while to be shipped, and most of them canвЂ™t be modified. IntroductionД®ither to use emulators to play the ROMs from your GameBoy cartridges or to modify those ROMs, the first step is always to extract the ROM from the cartridges.
