I still have around 50 carts in my closet I haven't been able to part with yet, but it's just more convenient to use my Everdrive.
Several years back I bought a new old stock pin connector from someone on Digital Press. The guy raided a electronics store that went out of business that used to be a official repair center. Wish I had bought more than one.
That's about what I've held onto, the gems in my case of what I had been gifted, bought, or otherwise received back in the 80s and 90s. I've kept nothing that was first picked up in the 21st century for both the NES and SNES and those dropped goods have benefited me greatly with the moronic prices people are paying on things. A fool and their money will so be parted, which is fine by me if they're fool enough to bid war things up.
I've got these games in order: 115-in-1 Famicom Supervision (Pirate), 1942, 1943, Balloon Fight (CI), Blaster Master (CI), Bomberman II, Castlevania (CI), Castlevania II: Simon's Quest, Castlevania III: Dracula's Curse (CI), Chip 'n Dale Rescue Rangers, Contra, Crystalis, Darkwing Duck, Donkey Kong Classics (CI), Donkey Kong 3, Duck Tales, Duck Tales 2, Faxanadu (CI), Final Fantasy (CI+maps), Gargoyle's Quest II, Ghosts 'N Goblins, Gradius (CI), I'm Kid Dracula (English Reproduction), Jackal, Kid Icarus (CI), Kirby's Adventure, Kung-Fu (CI), (The) Legend of Zelda (CI+Hint Book), (The) Legend of Zelda II: The Adventure of Link (CI), Mario Bros. (CI), Mega Man, Mega Man II (CI), Mega Man III, Mega Man IV, Mega Man V, Mega Man VI, Metroid (CI), Mighty Final Fight, Mike Tyson's Punch-Out!! (CI), Popeye, Raid on Bungling Bay, River City Ransom (CI), Road Runner (CI+Tengen Sleeve & Poster), Silent Service (CI), Spy Hunter, Stinger, Super Dodgeball, Super Mario Bros. (CI), Super Mario Bros. 2 (CI), Super Mario Bros. 3 (CI), Super Spy Hunter, Teenage Mutant Ninja Turtles, Teenage Mutant Ninja Turtles 2: The Arcade Game (CI), Teenage Mutant Ninja Turtles 3: The Manhattan Project, Tetris (TENGEN) (CI)
That bootleg has the following games:
http://bootleggames.wikia.com/wiki/Supervision_115-in-1 --97 legit games, 1 dupe, rest are 'pro' speed hacks of black box titles, it's the best multicart on the market for variety. Second best these days if you're in love with that Super 150-in-1 out there now using new quality parts that has like 90% of the $100+ trolled games on NES the shills have made grossly expensive (Samson, Flinstones, Gun-Nac, Jetsons, Panic Restaurant, etc short of basically Bonk and Bubble Bobble 2.)
Kim-- I agree go for it, it would make a lot of sense, just be careful not to spend yourself into the trap so many of these fools these days have fallen into. With a real system I'd get the Super 150in1 I noted ($30~) on ebay, $20 on aliexpress.com and you'll save thousands of dollars in priced up solid games.
