So this leads me to believe I have a contact issue. None are bent. But on the AK2i I can kind of see little marks on the cartridge contacts and a few of them look a little less worn than the others. Is it possible a DS contact is bent only slightly? Will buying a new slot-1 fix this issue? From what I've seen ( only very little) you keep the same contacts just the slot gets swapped out. I've cleaned the contacts on the ds lite and the ak2i with 91% alcohol ( and I let it dry for a while before sticking it in, I know better). Still had issues. If I blow in the slot and reinsert the cartridge multiple times it works occasionally. Sometimes I blow very hard and it still takes about 10 tries to get it to boot. My R4 works much more easily than the AK2i. So is this a cartridge problem or a ds problem? Possibly a mix of both? My R4 works great in my phat ds. I've had it many years, its actually one of the original white ones, there were still updates when i bought it. and the new wood firmware works great, makes me regret buying the ak2i. Even when the DS lite does work, I normally do not remove the cart very often, it will not work on the next attempt to use it. let me know what you think, any ideas are welcome and helpful. i can take the ds lite apart but im trying to not have to.
