Which adapter are you using, out of interest? I've got a Megakey and the pcb is beveled so happy to use it. I played Demons of Asteborg that way... until I fucked it off for being far too hard for its own good.
Anyhoo piccies:

So, very much in keeping with original carts... the game genre graphic on the rear of the insert is a little dim, it's the right logo, but I'm going to say it was scanned, and not at a high enough rez to make it look strong enough in print.
The case is very tight, so be careful when opening as your cart may spill out. Not sure why the bothered with the retail hanger, 99% of Jap boxes never had them... may have to remove if it won't bend so it can be stored properly.
I'll try and get some time in on the game itself later.
