Is the G6 or the Cyclo DS better? Besides the fact about the memory being unable to be changed. Here are some things to consider. 1. G6 has editable cheatcode lists. 2. G6 is a lot cheaper. 3. Cyclo has SDHC which allows a lot of memory. 4. Casual gamers like me don't use a lot of memory. We don't even usually listen to music or watch movies. But basically number 2 is the best thing for me.
