If you're going to be writing a C program, why not allocate space in the game for the data and have the C program directly edit the game? This could be later expanded to much more too like a game editor or something. That was kind of my plan. I would do the table route. For data of a defined size, ...

I was wondering... What is the best way to store game data (in a NES game) that can be easily loaded and edited by a computer program (written in something like C)? There are many types of data in the game, some fixed sized entries, as well as variable sized entries. I want to keep game data on 2 fi...

I finally had the time to desolder my mess and do it the right way. Worked the first time. First I tried FF1, then I tried my own RPG project (which was the point of putting this together). Both worked great with no problems. Thanks again Bregalad, for clearing up my confusion with the instructions....

Welp. Atleast I hated the game I destroyed. Guess I'll try again...

Sorry about the picture, I'll get to that. In, "Using EPROMs in place of NES Mask ROMS", it goes Bend up pins 1, 2, 24, 30 and 31 (or cut tracks 2, 24 and 30) Solder pin 2 to hole 24 (A16) Solder pin 24 to GND (OE) Solder pin 30 to hole 1 (A17) I bent the pins up, soldered a wire from hole...

This is my second attempt at making one and, sadly, I get the blue screen of death. I followed the directions from the "Using EPROMs in place of NES Mask ROMS" text. I checked my EPROM to make sure FF1 (for test) was programmed to it correctly. I'm not sure what I did wrong.... Here's a pi...

Thank you tepples, I understand completly. I have another question though. In "CA65 sprites.s", where you define the segment for the code for drawChar "CODE", is there a way to make the segment optional (to the project using it)? I know I can use a constant symbol inplace of &quo...

Yes. I know how header files work in C.

I'm having problems figuring some things out using ca65, and am looking for help. My first question is, how do you compile a program with several source files without using one big .include list. Lot's of my files depend on others and if I tried to address each source file, I'll end up .include'd a ...

Well, it was either DTE or Huffman. In my situation, I wanted the tiny dictionary needed for DTE (SNROM RPG game). My dictionary of 64 entries (128 bytes) was conveniently put on the fixed bank. It was very easy to implement and I saw reduction in different text areas of about 20%-40%. If I had a wh...

Thank you for the replies. DTE seems simple enough but; I'd have to setup a directory of text snippets saved in individual text files, write a program (C probably) to go through all of them, and .incbin the results, plus the 2 char table used to decode the compressed text. Quite a pain but maybe wel...

Sorry if this has been brought up before, but the search function on this board is broken (atleast from here). Me and friend of mine are waist deep in a small RPG project, and well, I don't see many of our goals getting accomplished without some sort of text compression. I'm not familiar with any me...

Thanks. Thanks for the help. I found a good deal on eBay, and also got a ZIF socket. Hope everything works.

Thanks again everyone.

As you can tell, I'm very to new to this. I followed the instructions I found here http://nesdev.com/NES%20EPROM%20Conversions.txt last week. So I've already "mangled" the cartridge board. I was just wondering if this EPROM chip will work http://www.digikey.com/scripts/dksearch/dksus.dll?D...

27C256, that's odd, beacuse all of the 27C256's I've seen on the internet have 256k. Which is what I wanted. This EPROM pinout chart gave me the impression that they made 32 pin ones. So, 32k x 8 doesn't mean 256k? EDIT : I thought they meant byte, not bit. Futerlec sells 27C2001. But the pinout doe...
