Is there any way to fit the chips in the cartridge? The only reason the chips stick out and require a hole in the cartridge is that the instructions I pointed to are for making a REprogrammable cartridge (which involves soldering a socket onto the board and then simply inserting EPROMs after, to al...

To copy permanently, in the best case you need :

And probably the most expensive item on the list, an EPROM programmer.

I'm not going to explain all this here, but I think anyone should be able to follow the steps found on these sites. Between them you should be able to come up with a parts list and clear instructions: http://www.raphnet.net/electronique/nes_cart/nes_cart_en.php (probably everything you need to know)...

Again, I understand the explanation but I am in fact using NESASM and can't seem to get this to work. Does anyone know how to handle this in NESASM? Thanks for all the help

wow, thanks for the great explanations. i'm still a bit hung up on indirect addressing. I understand how the actual addressing works I think, but how do I store my background data in a specific location to access by indirect addressing? For example, I have this included in my code at the moment, how...

so what does one generally put in the infinite loop? anything?

Thanks again Celius. This has been really helpful. But this all leads me to a question. Isn't it better to perform as few operations during an interrupt as possible? I understand that what I am doing at the moment is taking less than 2200 cycles and therefore will complete without flickering during ...

Ok cool, that does prevent the flickering. So I guess I actually don't really need a sprite on screen for the rom I'm trying to make (sort of a live visual type deal), but I am wondering, how do I draw an entire screen full of background tiles instead of just a few rows. I'm already working with 128...

this works but i still get the flicker. hmmm

Thanks for the help. I think it's getting too late for me to think about this (i'm in NH). I tried to do what you said but I don't think I get it. I'll take another look in the morning. Here's my code in case you'd like to take a look: .inesprg 1 ; /////INES Header///// .ineschr 1 .inesmap 0 .inesmi...

I pasted in both of those parts together just after my "infinite" loop starts, and you're right, it doesn't flicker anymore, but now it takes about 4 seconds before I can change the background by pressing A. Is there a way to make this a lot quicker? Is it possible to load my other nametab...

Thanks I got Tepple's editor so I'll try that out. Regarding the flickering, I think I am running it during VBlank. I'm truly a noob to both NES and assembly, so I might have this wrong. This is the code that controls the background when A is pressed: AKEYdown: ; code executed when A is pressed vbla...

Celius, yep that worked. I still get an odd effect when I execute my rom, however. It's a flickering of my background that occurs at the bottom of the screen (I only want the tiles to appear toward the top, just moving slightly up and down with A presses. It might have to do with the way I'm just ad...

This helped a lot with my problems. Thanks

I have been having trouble with name tables and attribute tables. I was trying to use GBAguy's map2bin program, but I was getting annoyed with it so I decided to try other programs. I wanted something to help with making name tables and attribute tables, so I tried NES Screen Arranger but I can't fi...
