    Default Create a NES reproduction game without any programming!

    Here's a "how-to" on creating Thexder for the NES without the use of an EPROM programmer.

    Step 1) Extract the mask roms from the original Famicom game with a de-soldering tool.

    Step 2) De-solder the mask roms from 10 Yard Fight to use the circuit board.

    Step 3) Solder the Famicom mask roms onto the NES board.

    Step 4) Test the game.

    Step 5) Create a custom label and voila!

    Not a bad piece of work there, but it's also not always that cut and dry. Sure 10 Yard Fight works for the most basic of Famicom games, but when you get beyond that you'll need to know using bootgod a 100% compatible board chip for chip where you can do a pop n' swap of a couple chips (CHR and PRG) to keep up the pace because if you mismatch the memory mapper you're hosed.

    Some stuff just won't work with Japanese special chips like most of the good stuff Konami put out, so there you need another blackbox game with the converter inside and go about cannibalizing one of those to make a game out of it.

    I forgot to mention the circuit board discrepancies. Thanks.

    Eh no problem. I had been considering doing it myself before but I just never got around do it, then stumbled into a super cheap bootleg with a honeybee attached no one else on ebay noticed, and after that the Retron5 showed up so I gave up.

    Why not get a Famicom to NES converter? They are not that hard to find and you still have the cool looking famicom cart.

    You're right by pointing out that problem. This only works well for games like "Binary Land", "Choplifter", "Dig Dug", or "Battle City".

    It's a hobby - pure and simple.

    Also, the official Famicom/NES convertor (which I prefer to use) is becoming more and more scarce in the market, and they're way too expensive on eBay.

    That's for certain, once the predators got out there and realized there was a market for those early era famicom adapters they've been checking carts and charging like over $25 for them on ebay since like sharks. It's approaching a point you'd be better off scoring a third party adapter, and it is a better deal if you find one with a game attached to it.

    Yeah, I have been looking for an early 5 screw game with an adapter for several years with no luck in the wild. Recently I won a raflle for one so that'll be exciting to play with finally.

    That's cool good for you. Before people caught onto the craze of it a little over a year or so (less than 2) ago locally I was able to go through the local chain shop and find a couple using the known visual tests, same place also turned up 4 copies of the Wii Fire Emblem game for 1/2 the going rate and the gray Turok Rage Wars too. It's been filcher picked over for months now though and they've thanks to half price books stopped doing anything but ebay or higher too.

    I remember years ago finding Famicom games or multicarts with converters attached for under $5 at thrift stores. I'm still surprised to hear the converters became so expensive. Having multicarts are a pretty decent way to play Japanese only released games on North American consoles, if you don't have the original carts with a converter.

    I am too, but I think how it worked out was that someone got the idea if you have a 100in1 cart, you can charge a dollar a game and pitch it as a great deal. As far as the converters go, I have no idea, probably completely the internets fault for people catching on to what they got screwed out of by the Japanese for the old systems.

    I keep a Supervision 115in1 around which has 98 unique games (others are 1 dupe, rest are pro speed hacks) and the selection on it is just amazing but it's also in a standard NES shell. I do have the Golden Game 260in1 in a Famicom case, it has those rare Taiwanese made games like Wild Ball and his other stuff like Magic Crystal on there and Brush Roller which is good stuff, but I never use it, oddly no one seems to want it as I can't slide it rhough ebay (got caught) and multiple forums didn't care either so I think some stuff is more popular than others.

    What's really nuts is how much certain converters go for just due to who made them. Look at a generic one versus a Honeybee and the price changes a lot, especially if it's the gold painted one which is dopey since it's identical to the gray cart.

    Wow!!! I can make repros without a programmer too!!!

    Step 1) Buy two eproms from Hobbyroms

    Step 2) De-solder the mask roms from 10 Yard Fight to use the circuit board.

    Step 3) Solder the eproms roms onto the NES board.

    Step 4) Test the game.

    Step 5) Create a custom label and voila!

    I dunno...seems to me sacking Fami carts just for the mask roms is a complete waste. Not like the data is pure or better on a mask rom.
    A 1 is a 1 is a 1 ...be it on eprom, mask or flash.

    If you said your wife ball gagged you and then crushed Fami carts while naked in her stiletto heals...that I could respect
