Re: camera scroll walls

The Donkey Kong Country series fiddles with the camera throughout the course of some levels. I don't know the details of how, but there might be a level editor out there that could shed some light.

Re: Games and highscores

I edited my original post with the patches. The Tetris one should probably be converted to an xdelta patch.

Re: Difficulty logging in while using 4G

I haven't had problems logging in, but I was repeatedly logged out while trying to post a reply from my phone while on 4G/5G. I eventually just posted from my computer.

Re: Structuring enemy behavior

Is there a place on the internet where I can read more on this? About Ninja Gaiden specifically? Probably not. I re'd parts of it a while back for a rom hacking project, and have since lost the notes with the AI code commented. I do have an older copy with much less comments if you are interested. ...

Ninja Gaiden enemies use a state machine that calls shared functions.

Re: memory and object patterns?

I hard code certain slots to specific types so assumptions can be made when it comes time for collision and other things: 0: Player 1 1: Player 2 2-4: Player 1 projectiles 5-7: Player 2 projectiles 8-31: General use 32-39: Map "doors" You can also add data fields to certain groups without ...

Just an update on this project that still hasn't been given a title: Power Plant https://i.imgur.com/s2waAyb.gif This is an older version of the graphics/palette where I was playing around with parallax (that scrolls the wrong way :D). https://i.imgur.com/BrVUwWJ.gif A more recent version of what th...

Re: What keyboards do you use for programming?

I have a 20+ year old Compaq rt7h00. For the longest time I kept around a second one, but this one just won't die.

About 5 years ago I thought about going wireless and bought a SMK vp6610, but went back to the Compaq because it felt better when playing games and the mouse felt too small for my hand.

Re: Amount of BG tiles used in 8-bit and 16-bit video games

For the NES: If a game has chr-rom and dedicates a 1K slot to a 4-step animation, would you count that as 64 or 256 tiles? Some games store a font in each 4K/8K bank. Others store non-graphic data in chr-rom. Contra uses chr-ram and streams in different tiles during the level, usually at the boss. S...

Re: Tool: MapEd Pro

In making this example, I fixed quite a few bugs. There is an obvious* one in the current version when background tiles are set to use $1000. In the metatile editor, when you click on a tile to edit it, it will always draw from $0000. It does show the correct tile when building metatiles and in the ...

Re: Tool: MapEd Pro

Creating a new project is definitely problematic at times and the workflow is not always clear. Especially with a lack of documentation.

I can post an example project when I get home later today.

Re: Was there an NES expansion chip like SA-1

I whipped up a mapper for the powerpak that does just that. Eventually ended up at FME-7 level complexity with MMC5-like extended attributes, so discrete logic is probably not feasible.

Re: Clearing the memory after RESET.

Page 2 is commonly used for sprite DMA, but is not a requirement of the hardware itself. Based on the code you posted, it seems like the NN tutorial does just that. Having a Y and X position of $00 would put all sprites in the upper left corner, possibly in view of the player, while $FE ensures that...
