Hey Retro, I am looking to program a basic tile viewer / editor which allows the user to view tiles from a rom file, export the full images and import custom images. This sounds like a very ambitious project and to be honest, it is, but I'm not entirely clueless. I know the offset of each graphic that I need. I'm just having trouble figuring out how to actually program it, I know I would need to read in the data, display it to the screen by re-arranging it and then allow for importing and overwriting and exporting of sprites, I am just completely clueless about it. I program mainly in python due to it's flexibility and ease of syntax, if that helps. I hope someone can enlighten me as google provides very little help.
