Hey, so anyways i was trying to convert a png file into a sprite using the buildchar program. but when i try to convert the sprite into a png, it gives me an error. the error says: Invalid character in the given encoding. Line 1, position 1. Idk what this means so can you try to figure out what's causing the issue to pop up?

Hi, Your file have some tiles with overload colors. I paste the content of the documentation about file format spécification to build with buildchar:

About input files format: Picture files used in chardata.xml must be PNG format, 32bppArgb. Define transparency by pink color (#ff00ff), or simply use transparency. Size must be multiples of 16. About colors: There is no limits color wise, as long as each tile is transparency + 15 colors max, you can use pics with hundreds of colors. If your file is rejected for using too many colors per tile, erroneous tiles will be shown in a reject.png file

Hi,

Here is a way to solve the problem.. Update Neocore to version 1.0.4 from the master or release/1.0.4 branch Delete the build directory if it exists Compile the hello sample for example (so that the kit installs and compiles the lib) go to the samples\issue_80 folder mak Normally you should get a sprite reject type error Run the fix-background.bat script mak run
