Is there a good reference around for coding for the MMC3? I found a simple tutorial for the MMC1 on the wiki and I'm trying to gain an understanding of it. So, I see the instructions to perform these commands, but I don't get why: lda #$0E ; vertical mirroring, fixed $C000, 8 KB CHR pages sta $8000 ...

I also wanted to say that I'm pretty sure everything you mentioned in the first line about arrays and pointers isn't too hard to do on the NES. I'm not experienced with C so I have to guess a little as to what you mean, but I think it's stuff I've already done in 6502, and I just started. Arrays are...

Someone with more experience could give you a better idea of what sort of console would suit you. If you did do a 2D NES minecraft, the first thing that came to mind is that it would probably be easy to have a lot of blocks on the screen if you only process them as sprites when moving, and set it up...

I'm pretty new here myself but I think I might be able to help a little: Your interrupts are when you want to use the stack. Like on NMI. Push your registers onto the stack at the beginning of NMI, and then pull them off at the very end. Then you'll always have the exact same register values when yo...

I THINK it's a big DC motor. This are electric. General Electric, in fact!

I vote for the late Air Chief Marshall Fu Fu of Thailand.

I'm not making this up. I wouldn't dare to invent this.

I think you're doing it backwards. Unless you already have a person drawn that you didn't upload, I would start with designing the person first. How else will you know where the arms connect? If this is the FIRST thing you draw, you'll have to scale everything else in the game to your gun. Seems bac...

I think I fixed it! Most of the problem was due to the fact that I had my data entered incorrectly with two end of frame tags in a row. I'm going to upload an updated version and see if I can get anyone's opinion on whether or not this animation code is any good and whether or not it's worth buildin...

152 Branched to "ReadyForFrame" instead of "ReadyForStandFrame". Fixing this removed the bug allowing her to turn in stand state. She also now reverts to facing right when going back to stand as she should. "ReadyForFrame" is a label for the walk animation, but since it...

Okay, here it is. This is my very first project for NES. It was actually working pretty well, up until not too long ago, I was adding features and somewhere along the way it started to mess up. Okay, the main thing I was aiming to do was set up a system for Metasprites. Right now it's set up so that...

Hello everyone! This weekend I finally took the leap and installed Windows and got to coding. I wanted to try to do a simple project this weekend with some metasprites, animations, and maybe a little controls. For the most part I succeeded at what I was doing but started having a few bugs at the end...

Say you do like SMB2 and SMB3, both of which use the MMC3 with CHR ROM, and bankswitch the player's tiles at PPU $1000-$13FF. You can do one of three things, one of which does reduce enemies' animation speed: Bankswitch each of three enemies' tiles into $1400-$17FF, $1800-$1BFF, and $1C00-$1FFF. Th...

I'll definitely try tweaking the attack speeds. On the stronger attacks, I actually want them to be slower. It's the trade-off of using a more powerful attack. Kind of like the smash moves in smash bros. I may actually redo a lot of the animations. When I did some of the first ones, especially the a...

I think this sort of thing is exactly what the NES community needs; a tool to make the development of new games for the console actually practical.

I'd like to help if there's anything I can do.

I'm being given the impression that the GIFs are misleading since most likely they aren't animating at the intended speed (I bet those attacks are meant to be much faster, but look awful at the speed shown here). Any browsers that's I've seen them on seem to play the intended speed, 1/10th of a sec...
