[Bobissad]

Hey guys
What's the cheapiest way to back up a gameboy color sav to pc ?
I have a Gameboy Color, Game Boy SP, DS LITE with a Linker and 3DS.
Can I use any of those to back up my sav and keep it safe in my computer ? If not what's the cheapiest method.

Not really - a GBC homebrew where you swap the cards to copy data to a flashcard or serial port is possible (and probably exists) but would be very inefficient
The GBA runs at 3,3 volts (while GBC mode runs at 5), selected by a mechanical switch, so it has no advantages compared to the GBC - you can't use download play to avoid the GBC flashcard to run that homebrew

The most cost-effective GBC dumper (as in, something you can at least partially reuse or resell afterwards) is an Arduino (the models with more pins than the Uno) + a GB game socket (from a broken console - even a DS can be used if you break off the tabs that block GB games) (+ of course a PC)
