So I'm trying to resurrect a couple of gameboy flash carts from way back that have been collecting dust in my closet. They are so old that the software to transfer files to them is meant for windows 98/ME/XP. I took an old computer I had lying around with Vista on it and downgraded to XP. I thought I had a good serial number for it, but it doesn't seem to work. In retrospect, the serial might be for the 64 bit version and not the 32 bit one.
I really don't want to spend much (if anything) on a serial for an OS that is way out of date and no longer supported, especially since the machine will only be used for these flash carts and possibly to run older emulators that work best on XP. I'm wondering if anyone might have a spare serial laying around that they aren't using or if someone can recommend a place to get one cheap (or better yet, free)?
