I've tested TWO Neo Drift Out carts. The first I bought on eBay and returned it for a refund because I thought it was bad. The second I bought from a forum member. Same issue. So... doh.
I've tried it in all slots. MV6 does not "see" it. Verified all slots work with other games. Found a MVS...
I'm switching to a multiple cab arrangement and no longer need my 4-slot. What I need is (2) 1-slots.
The 4-slot has a graphics issue (vertical dotted line). I've tested each slot and different games and it is consistent. Not all screens in a game exhibit the issue, and some less than others...
