The ROM runs on everything I tried without issue. I've tested it on an Analogue Nt Mini Noir, Retro USB AVS, MiSTer FPGA, a clone Famicom console using real NES chips and another using aftermarket chips as well as the emulators in Batocera and Retrobat. All run it perfectly. It's a fantastic co-op game. It reminds me of Balloon Fight and Joust. This is a badly needed multiplayer addition to the NES library.
Nobody to play with? Worry not, the CPU bots will give you a very fun challenge playing alone. It's been a long time since I've been this excited about a new NES release and it does not disappoint.
