Ah, so it IS overwritten? Okay, then one field it is.

On an interlaced CRT, doesn't the beam for the next field hit directly under the previous, thus causing the scrolling affect you see when you look at a CRT from the side by moving your eyes upward or downward? Since the NES is essentially 320x240 (clipped on borders) X 2, it's obvious how it can dis...

Can I save some cycles by using the zero page? For copying an entire page it seems like a good sacrifice... Oh, & the screen-black-er-ing subroutine is what I call my subroutine that disables the background & sprites to check if someone's cheating. BTW, is there anyone here that has experien...

The useless memory clearing routine I took from NES101? (I write to memory before I read it anyways so it's pretty useless right now) I was unaware the NES starts at the reset vector. Then do games like Kirby's Adventure (skips the intro on reset) set a variable in memory to determine if it's a hard...

Okay, I'm trying to get this sprite to move, so I got this simple incrementing code in my vblank routine. Well, either attachments are disabled or I'm overlooking the attachment button, so I'm just gonna copy/paste my entire far-from-finished code here: *=$C000 !cpu 6502 !to "gameprg.bin",...

wouldn't you have to wait an extra vblank for the original field to be wiped out from the interlaced video first? That would bring a single shot to 2-6FPS, & therefore very noticable & annoying in my opinion.

STILL wondering if the Zapper has to be strobed! :P

Can't you just cut the GNDs as well?

EDIT: OR couldn't 2 diodes (one for each GND line) do the trick?

Once again, simply cutting off a cartridge will initiate BRK to $0000, & another cartridge can be inserted, assuming the next game doesn't assume empty ram is #00. I've tried this before.

The whole CIC theory, however, won't work. It will continue to reset.

Quick question: Does the lightgun need to be strobed?

How about the intro in Megaman II w/ the intro text saying something nice about your hopefully to-be fiance then at the very top it says "WILL YOU MARRY ME?", then on the "START | CONTINUE" screen have it say "YES | NO". EDIT: Oh, & w/ the Megaman sprite at the top ...

I'll start off by saying this project doesn't make any sense. Why would you want to permanently solder your games to a floppy cable instead of buying cartridge connectors? This will not only look horrible but will be extremely fragile. Who the hell said anything about soldering cartridges to the fl...
