Yay, NGPC! I picked up one at a Best Buy with Sonic and a few other games somewhere around 2,000 then bought a second one packed with 6 games for like $49 some years later. I'm not entirely sure which games it came with, but Faselei and Fatal Fury were in there iirc. I always assumed there was a ton of left over old stock that somebody decided to try to make some money off of. The second set didn't come with any manuals or boxes/cases, just the games.
My one complaint about the NGPC was the sprites on the system having only 4 colors (one of which being clear) was always something of a buzz kill; this was particularly true in the many fighting games on the platform. Games that got away with not using sprites, like SvC Card Fighters and Ogre Battle, looked waaaay better. The port of Ogre Battle compares alright even to the one on the Super Nintendo which was a pleasant surprise. I always wondered if there were any games that would do things like layer two sprites on top of each other to get around the color limitations but I never owned any that did so. Seeing Dark Arms in actions shows that it could have been done, I just wish more games had done so.
