Describe the issue.

This line myFile.write() should be removed as readDataArray_2600() already writes the data to the file. Otherwise you get extra data in the file. case 0x04: // F4SC Mapper 32KB \w RAM case 0xF4: // F4 Mapper 32KB for (int x = 0; x < 8; x++) { readData_2600(0x1FF4 + x); if(a2600mapper == 0xF4) { readSegment_2600(0x1000, 0x1200); } else { outputFF_2600(0x100); // Skip 0x1000-0x10FF RAM readDataArray_2600(0x1100, 0x100); } readSegment_2600(0x1200, 0x1E00); // Split Read of Last 0x200 bytes readDataArray_2600(0x1E00, 0x1F4); //myFile.write(sdBuffer, 500); for (int z = 0; z < 12; z++) { // Set Bank to ensure 0x1FFC-0x1FFF is correct readData_2600(0x1FF4 + x); sdBuffer[z] = readData_2600(0x1FF4 + z); } myFile.write(sdBuffer, 12); }

thanks for the hint. Should be fixed my only 32k game now dumps fine. Please verify.

I verified this change with my D.K. VCS cart and it dumps fine now.
