 # Open Source Cartridge Reader
-This project represents a community-driven effort to provide an easy to build and easy to modify cartridge dumper. All the Arduino source code along with the PCB design files and detailed build guides can be found in this Github. Happy making. 🔧🔨😊

-Entries start at 0x0 divided into 3 Byte segments   
-   
-For example, let's look at the start of the mapping for a multi-game cart:     
-A8 00 00 71 04 00 48 94 04 separates into   
-A8 00 00 MENU    
-71 04 00 GAME 1   
-48 94 04 GAME 2   
-   
-Byte 00 of each entry contains the MBC Type, ROM Size, and SRAM Size (start).    
-SRAM Size is 3 bits across Byte 00 and Byte 01.   
-     MBC SZE SRAM    
-A8 = 101 010 00  0 MBC5, size 2 = 128KB   
-71 = 011 100 01  0 MBC3, size 4 = 512KB, SRAM 8KB   
-48 = 010 010 00  1 MBC2, size 2 = 128KB, SRAM MBC2   
-   
-Byte 00: 1st 3 Bits = MBC Type   
-        000 = MBC0

-        011 = MBC3   
-        101 = MBC5   
-    
-Byte 00: 2nd 3 Bits = ROM Size (minimum size is 128KB due to block size)   
-        010 = Size 2 - 128KB   
-        011 = Size 3 - 256KB   
-        100 = Size 4 - 512KB   
-        101 = Size 5 - 1MB   
-   
-Byte 00: Last 2 Bits (bit1..bit0) + Byte 01: 1st Bit (bit7) = SRAM Size   
-        00 0 = NONE   
-        00 1 = SRAM MBC2    
-        01 0 = SRAM 8KB  
-        01 1 = SRAM 32KB

-Byte 01 contains the SRAM Size (end) and ROM Block in the Flash.

-Going back to our example cart:   
-A8 00 00 MENU:  MBC5, size 2 = 128KB, ROM Block 0, RAM Block 0 (Ignored since SRAM is 000)   
-71 04 00 GAME 1:  MBC3, size 4 = 512KB, SRAM 8KB, ROM Block 1, RAM Block 0   
-48 94 04 GAME 2:  MBC2, size 2 = 128KB, SRAM MBC2, ROM Block 5, RAM Block 1

-#### NBAJAMTE.eep    
-NBA Jam T.E. Rev 0 has faulty code that will erase the EEPROM when the cart is played on the console. Solution: Write the included save file to the cart.  Play the cart on the console as normal.  Create new saves as needed.  When done playing, HOLD THE RESET BUTTON DOWN BEFORE TURNING THE CONSOLE OFF.
