Game Reproduction Tutorials

[ujnhunter]

Thanks for the info. I'm looking to make an english SNES game soon.

[Chris Leach]

this is just what I been looking for! Ive got everything to make my own carts including the eprom burner, but I would like to see more tutorials on how we can just pick a rom from the net and know how to putit into an nes format....better yet, I would really like to take my famicom games and put them into nes cart format? Any tips on this..I have about 200 I could do....

Much rather have them be in nes format than famicom..>!

I'm not sure what you're asking here. You need a NES ROM, which will be 'NES format'.

I would really like to take my famicom games and put them into nes cart format? Any tips on this..I have about 200 I could do....

You have Famicom carts that you wanna turn into NES carts? This isn't really feasible. I mean, it IS technically possible, but not feasible. Since Famicom carts have a different pinout than NES carts, you would need an adapter for each cart. A better option would be to buy ONE adapter that will let you play Famicom carts on a NES (instead of trying to turn each Famciom cart into a NES cart). We were just talking about this in this thread:

I apologize for not being clear...I would like to download the .nes or whatever it takes for each specific famicom cart I have and put it on a donor cart for each of my famicom carts....

Then I would be able to sell off the originals...I like the nes look better

Oh, well in that case I can tell you it wouldn't be worth doing for most games. Most Famicom games are nearly identical (if not completely identical) to their NES counterpart. It wouldn't be worth making a reproduction if the original official NES cart is only a few bucks. This procedure is only suppose to be used to put games on carts that don't have an official release. What would the point be of putting NES ROMs on donors when you could just buy the actual NES cart? Instead, you'd be better off getting a flash cart...

I would be using the roms from games that are not nes releases, like splatterhouse and making it with a sticker.so its in the nes library....? Looks cool would be the purpose..maybe its a stupid idea, but I like it.....for games like the Japanese Contra, and others!


Ive got a flash cart from retro usb for my nes, not the same feeling as having the game on cart..you get to see a picture of what it might be like..then there is always box reproduction..thats a whole nother story right there..the feeling you get from looking at an nes collection and being able to pic up the box and read the back to see if you are ready to get involved with the world that exists inside of that one specific nes cart...you dont get that feeling from loading a rom off of a memory card.....there is just no way...

Ah, I see what you're saying. It's just that you said you have something like 200 Famciom carts that you want to turn into NES carts, making me thing most of them are common NES games already.

Be aware that there are instances were you can't do it, or it will be difficult. For example, I don't believe there's a NES cart that exists that you can put the Famicom version of Contra on. It uses the Konami VRC2 chip and I don't think you'll find a compatible NES donor. But the PowerPak flash cart can run this mapper (23). It's listed as buggy, so let's hope that a future update will get this mapper running good.

Another example would be Akumajo Densetsu (Castlevania 3). This game also uses a special mapper, the VRC6, so you wont be able to put it on a NES cart. This mapper (24) is listed as good for the PowerPak.

And FF3, for example, is possible to put the translation on a NES cart but there is no 100% compatible NES cart that exist, you have to modify a cart for it to work.

These are the ones that are always in my head. I mean, it's not like Nintendo gave us a lesser version of a game just to spite us, there's reasons why, which will often make the Famicom version incompatible with the NES. For this reason, I suggest just using a Famicom system with the Famicom carts for 100% compatibility. Many agree. Either that or use the Famicom carts with an adapter to play them on your NES, but you wont have 100% compatibility.

I was using Contra Japan as an example because the game is so much richer in graphic quality and you get a cool scrolling map from the japanese release in between levels and there are cut scenes where the two main characters are talking to what appears to be the main headquarters using 80's style military walkee talkies....? They cut so much out of the usa release and it is just a nice add to my nes library.

By the way...you mention this as maybe not possible, I own an nes reproduction of this cart and its pretty nice...from the black label on the cart to the fact that the konami code still works?

Here's a tool I made for windows that takes the iNES header, and extracts the data accordingly. Source, executable, and batch is included. I've used it with DW3 and it's worked, and passes my own hex editor look-ups and it's split tons of homebrew ROM's fine, so I trust it, but if for some stupid reason it doesn't work, tell me.


EDIT: Also, with the Buggy mappers on the powerpak, I think it says that because it doesn't support the extra sounds yet, I think they may work, just not use the extra sound hardware on the carts.
