The NeoGeo Pocket SD FLASH cart is in production and I will start invoicing and shipping next week. Many thanks to my testing team at AtariAge for testing compatibility with (I think!) all NeoGeo Pocket console models and BIOS versions against the available games.
The cartridge will sell for £70 (UK pounds), which will include instruction leaflet and cartridge. No SD card is supplied, but the cartridge will accept any FAT (not exFAT) formatted Micro SD card up to 32GB in size.
