Now I really feel that I am making some progress! :P With some reverse engineering I could identify MMC3 and its pinout : http://nintendoallstars.w.interia.pl/romlab/famconn.gif http://nintendoallstars.w.interia.pl/romlab/pmmc3_2.png http://krauser.persiangig.com/image/GlopTopPinoutS.JPG Click here ...

I have another plan : I do need a MMC3 anyway, right? How about this : I can't find any MMC3 or its clone, but still I own two pirate cartridge which I am sure they are either mapper 45 (8 in 1) or mapper 44 (7 in 1), in both cases they are based on mapper 4, so what? I already own two pirate cartri...

Here you are : Mapper 45 Information This is another Kunio 8 in 1 pirate cartridge : http://up.iranblog.com/Files/bedb22715deb4d87b803.JPG I am sure this is also Mapper 45. There are three glop top, what might they be? CHR-ROM PRG-ROM ? You have mentioned "74HC parts" what is that? :oops: ...

Hi, I am back with another n00bish question

I have found a Kunio 8 in 1 nes game (size : 2,097,168 bytes) which is mapper 45.

How can I build a 60-pin pirate cartridge from it?

Do I still need a AX5202P?

Thanks in advance.

I don't know what you mean by "offset by offset", but maybe you didn't understand what I meant by "reprogram the whole game" either. As far as I had learned, assembly is a very powerful language. It is possible to do everything with it. But unfortunately it is very complex and c...

I want change Mapper 4 (MMC3/TLROM) to Mapper 2 (UNROM) Well, it doesn't really work like that. Mapper conversion is something you consider when the mappers involved are similar and share common features, or when the mapper you are converting to is a superset (it has all the features and more) of t...

If the game used a simpler discrete logic mapper (such as CNROM or UNROM), it would be possible to build it from standard logic chips you can buy anywhere, but the connector would still be an issue. How about changing the game Mapper? If I can convert MMC3 to UNROM, is there any change to use a UNR...

I am living in IRAN. Although there is not much good things here, I believe here is paradise! Anyway I am sure, I can't find any similar board here. So it seems that I have to play my good old nes games on my good new computer! But one more thing who made those 60 pin pirate cartridges that even aft...

Thanks to all of you. I am not worry about the programmer because one of my neighborhoods promise me to provide it for me. He is working on programing Digital LED Board for public places. (I don't know what is the exact name of them in English) I found the exact game board (Wow it is 60 pin, really ...

Alright, I can't reprogram my own nes cartridge. How about building my own cartridge? I have already searched google and I could find some sporadic document about making a programble nes cartridge : Main Guide : http://www.raphnet.net/electronique/nes_cart/nes_cart_en.php ROM Splitter : http://www.r...

What kind of cartridge is it, and have you taken it apart? You'll want one that uses normal memory chips, a lot of pirate carts that I've seen use glop-tops and you can't rewire anything (not easily) since there is no removable chip (just a blob of epoxy). I just want to play my desired nes game on...

I own a pirate nes console and a pirate nes cartridge (both of them are 60 pin). Recently I have translated a nes game to my native language and I can play it on my computer without any trouble but I really want to play it on my nes console! How can I do it? Can someone help me?
Thanks in advance

Changing: 69 20 ADC #$20 To 69 19 ADC #$19 is wrong. The #$20 allows for the " to be placed directly above the letters. Using your code above, you know that the PPU Address is being set by $607 and $608. You need to adjust the starting PPU Address for the text, so set a breakpoint for a write ...

Ok I made some progress. Here is my report : Finding the correct breakpoint address was really difficult but after reading KingMike's DTE document and some trial and error I could find it. I want to change these two lines which are appearing from left to right. http://up.iranblog.com/Files/593632ed5...

The VRAM address normally auto-increments, so you definitely will have to change the code in the game, possibly in several locations. You won't be able to make it the same size or smaller as the original, so you probably will have to find or make some free space in the ROM (in the same bank, in RAM...
