Rene of dbelectronics has posted an article on his site about possible dangers of using flash carts with your system. Some are fine, others are not. Worst are multicarts.

Quote from: ReneThe use of 3.3V flash in retrogaming can lead to serious problems. Following a lengthy podcast discussion on the subject I felt it was important to elaborate on the matter by:The 2nd version of the Turbo Everdrive is fine. The original isn't. Of course I have the original. Looks like I'll have to rebuying newer revisions of some carts and I hope Krikzz updates some of the others which have no good revisions, like Mega Everdrive X7, Master Everdrive etc etc. Apparently the Darksoft Neo Geo SD thingy is good. Not sure about the NeoSD.

- Addressing common rebuttals
- Listing devices which exhibit this problem
Let me be clear that using 3.3V Flash in a 5V system in of itself is not inherently bad; it can be done properly using level translators such as what has been done with the SD2SNES. What is bad, and what I am speaking out against, is directly connecting 3.3V Flash to 5V buses without proper interfaces such as level translators.
