You can use the very old Bung Device that uses the parallel/ LPT /printer port. Named Pocket Linker or NGP Xchanger
If you have someone with that older Flashmasta flasher that might work too. I think the device is called Link Masta (very rare)
If you can get an adapter (connector slots are hard to get) you can also build your own inexpensive Mulit Cartreader from Sanni :

I own a pocket linker but i dont know if i can find Software or a PC with printer port.
I builded myself the Cart reader from Sanni but i dont have an adaptor for the NGP Slot so the device is able to dump but i cant connect carts.
