On second thought, if you are modifying the code from the episode 5, then, I believe, I was still using the mapper 0 back then, so the bank switching shouldn't be available.
Where can i edit player sprites in latest episode and main_tiles_chr is not loaded in the example only intro and title when i used find keywords in notepad++
Just load the main.chr into an editor of your choise( e.g. Screen tool) and edit it. Note, the same character graphics are duplicated in other tilesets, so you will have to change them as well.
Oh, it is loaded allright, perhaps you have looked only in one file, it's not in game.asm
