Why on earth would you have multiple input routines? The normal is to read all the bits from the joypad and put them in a byte, since, conveniently enough, there are exactly 8 buttons in a NES controller. This routine is always the same, but each "game state" will read this byte and do di...

If you know where you're jumping from, all you have to do is something like: jmp ($40) Label: ... ;Address jumped to with jmp($40) ;blah code jmp Label .....(cut)...... This is okay to do, however you could eat up a lot of bytes having this sort of set up for lots of different routines. I thought o...

Anywhere where you make a decision to change game modes, you set the pointer to $40/$41. Probably not right before you jump to it. Good idea. So everytime you change a gamestate, you'd set a series of pointers for every set of gamestate-specific routines. Makes a lot of sense. How many different po...

Thanks for the replies guys! I have a lot of good ideas to think about. But I think I didn't communicate my question as clearly as I wanted to, because the answers didn't hit the point that was bothering me. I hope it will be a little clearer what I'm asking with this reply. I don't see it being tha...

Hello, I'm still in the design phase of my little one-screen game and I'm making a list of all subroutines I will have to write. I have a simple question about how to handle Controller Input. First a little info. My game has a few different gamestates (TitleScreen, Movie, Gameplay, Paused, GameOver)...

Sivak especially has been pretty active recently in releasing games.

Thanks a lot guys! That's a lot of great information. I'd like to hear from the CA65 people too. If you guys don't mind chiming in, it would really help me out. And anybody else who uses one of the other assemblers too of course.

Seems like "duck" is right to me.

Although my dictionary of old Japanese also lists "ahiru" as a derogatory term used by Edo-period boatmen for dancing girls/wenches. you decide.

Hello. I'm MetalSlime. You might remember me from the 4-way Dragon Warrior Scrolling thread . I haven't posted much recently, but I've been lurking. Working on that Dragon Warrior project taught me a LOT about basic NES programming, and it gave me confidence because everything started clicking. But ...

Great idea for a thread. This thread should be stickied. The first few posts especially will help first-time newbies get an idea of what they need to do.

I want to see more. When will we get the next video demo?

I've never actually looked at a Famicon cart closely, so I have no firsthand experience, but I googled really quick and found this: http://detail.chiebukuro.yahoo.co.jp/qa/question_detail/q116990246 He says to take a tiny flathead screwdriver and slip it into the seam on the side of the cart. When y...

Awesome! Congrats on finishing your game and thanks a lot for sharing the source code! How long did it take you from start to finish?

Oh, and Shinryu is the hardest enemy in FF5 (That means something like Death Dragon, right?) Sometimes it's hard to tell what a japanese name means without looking at the kanji, because many different ones are pronounced the same. In this case though, I don't think it means "Death Dragon"...

I'm embarrassed. I found the problem and it was that I wasn't in 32-increment mode. :) The reason is because before I tried to do everything (draw both columns and update the attributes) in one frame. That caused slowdown, so I broke it up into three frames. When I broke it up, I remembered to set 3...
