I contacted Working Designs previously about bringing out a Metal Slug collection for the PS2 or some other system. Did you guys realize that back in the day they were going to try and bring Metal Slug (the original) out (I don't know what system, but I'd guess the Saturn, since there was a MS on the Saturn... at least I think there was. Please correct me if I am wrong)? That's what the dude said in his reply. Also in his reply was that while anything was possible, WD doesn't try to go after that type of game any more... just RPGs and shooters (as in Thunder Force V style shooters, I think). If I still have the reply, I'll post it if anyone is really interested.
The easy part of bringing a Neo game to the US is that the translation and everything is already done. It's on the cart. They just need to emulate the system to act like an English system. And if they did it right, you could swap between Japanese and English, along with turning on/off the blood. How difficult could that be? Actually it would just be cool if Playmore released these games in Japan, but with the option to change all the settings, like playing in English. HOW HARD WOULD THAT BE???!!!
