Ha, that brackets/parentheses thing had me going for so long... I think it stems from the fact that NESASM originated as a 65C02 assembler, and by the time WDC had gotten around to the C02, they'd come out with their new official syntax, which used the brackets for indirect instructions. Still, pret...

I don't plan on ever using any version of Internet Explorer again. Ever.

"Comic Bakery is a computer game for the MSX, made by Konami in 1984 and later ported to Commodore 64 by Imagine." "'You Spin Me Round (Like a Record)' is a song originally released by Dead or Alive on their 1985 album Youthquake." However, the SID file I have is dated 1986, so ...

Well, I made my first attempt at hooking up the RAM cart to the paralell port today, but no luck. The program and cartridge seem to be communicating with each other (the "disk in" signal is accurate and the program recognizes read attempts,) but nothing will load; it always reports an erro...

(I was jesting, treating "a Nesticle" as if it were a reference to an actual console.)

I actually went back and looked over the JUNKDEMO code once, and as I recall the problem was that it assumed background and sprites were enabled on bootup, which is not the case. A quick run-over of its PPU init section and comparison with nestech.txt's $2000 and $2001 documentation should reveal wh...

As a Joe Gamer back before I really got into homebrew, when I read about the lockout chip and my SMB3 cartridge began failing, I decided to give it a try. 45 minutes later, my razor blade and I had got the pin cut and SMB3 was working again. So no, I don't think the average person would be too leery...

Well, the Neo Fami arrived today, and it works fine, with one quirk: the quarter-phase pulse output, for some reason, gets output as a half-phase pulse wave. I've only tested it with Final Fantasy so far; my guess (I'm not sure about this) is that perhaps pulse setting 3 (three-quarters phase, which...

It makes more little threads to scroll through when looking for a specific old thread. Trust me, he's doing us all a favor.

Eh, you don't have to use C for that. I personally use FreeBasic for small utilities, as I find it's faster and easier to get a small command-line utility up and running in Basic than it is in C.

But hey, whatever floats your boat.

But Nintendo locked out the Camerica carts by putting some passive elements around the CIC in later NES board revisions. That's probably my problem. My NES is one of the modified NTSC NES's officially sold here in Brazil by Playtronic. Since these started selling in 1994 (the year printed in the ex...

Well, I looked up some reviews of the Neo Fami and the general opinion was that it's a good deal. (The price is definitely right.) One user mentioned that their unit broke after a few uses, but the company I'm buying from will allow returns on defective units, so I think I'll go with it.

Actually, that means it's not defeating the CIC at all. From what I understand (my own experiences bear this out,) a failed authentication just causes everything to be reset after 1/2 second.

Like I said, you really don't have to if you don't want to. I did so in my example code because it was written assuming that the text characters were located at the ASCII positions in the tile table, and therefore printed text (excepting foreign-language text which uses the accented characters,) wou...

The reason we've been going with powers-of-two (specifically, 128 normal characters and 128 DTE characters,) is because, when the value is loaded into the accumulator, its high bit gets copied to the status register's Negative flag (i.e. the high bit is treated as a sign bit,) allowing us to simply ...
