We've done some tests with NEO-AES (aka NEC version),3-3,3-4,3-5 and 3-6
The NEO-AES has problems with audio that we are trying to fix. The other versions work well.
If you have a 3-3 version, you may need a 5V5A PSU as the cart is more power hungry that a regular cart.
Please post here any issues that you have.
P.S. We've just released a new version of the menu. The changes are mainly for AES so it remember settings and doesn't restore to defaults everytime.
After updating the menu, you need to power cycle to completely reset the cartridge.
