but to answer the question, its easy to make a little samson cart, it need a mmc3 (mapper 4) donor with 1x27c010 and 1x27c020, it takes actually the same thing to make a mother on the nes, tho i was tempted to make repro of the expensive carts for myself, tho it takes the fun out of hunting for games, tho so far i sold alot of zelda parallel worlds, on the back of the cart it's clearly marked its a repro game of a hack of zelda link to the past, tho not sure if collectors/retro players are stupid or something, some of them actually thought Parallel worlds was an original game..... if you have any questions on repro carts send me a pm, spend the last 5 months doing reaserch, (while juggling the fact im a new dad also) and im still on standbuy on a project arseen asked me, but i need to further my research on tsop chips...... (looks at arseen, im in trouble now arnt i?)
