(Solved) struggling grasping nes graphic editors

(Solved) struggling grasping nes graphic editors
by on (#103331)
Hello all,

I run a windows 7 - 64bit computer and I'm only able to run a select few of the programs I find for NES graphics editing. I was wondering if someone could steer me into the right direction. Currently I have a bmp file with 4 different colors in it. Although I'm sure they are not all NES compatible I assumed that when pasting them into YYCHR it would recognize it as 4 different colors. When pasting I'm seeing it past it has white and black? Is there a set of instructions out there that shows me how to use YYCHR with intentions of developing graphics for a homebrew rather than editing roms graphics?

Also to give a better background to what I'm trying to do... I'm trying to take this BPM image and have it as a background in my "game" (I'd like to make a one screen greetings card really). Is there any tutorial out there that shows how to create backgrounds for games from scratch? Load a chr and set it as the background (or however you do it)? Also keep in mind I'd like to do this in C as I'm not familiar with assembly.


Thanks,
Jake

P.S any graphics tutorials you know of that are NOT related to rom editing please send my way :)

Try converting it to 4-color indexed (i.e. paletted) in some graphics tool (Photoshop, IrfanView, whatever) before copy-pasting it.

P.S. You can import a 256x240 BMP file to NES Screen Tool directly.

Checked it out and I'm starting to get a hold of things.... I also found out how to add the background via C, but I'm still trying to reverse enginer a few other examples t o see how the chr file is brought into it all... Also I started to use the nes screen tool and saving the nametables to my clipboard in C is not working :| any suggestions?

It works for selection only, as it does not make much sense to do with the whole nametable (you can just save it into a file).

Didn't even notice that :D thanks for the heads up.

YY-CHR is really easy to use, and it accepts bitmap data from the clipboard.
