Great that it was possible and thanks for the help!

Is it also possible to change the sprite or color so that one of the carts plays as Luigi?

I told you I was a noob

Thank you all for your answers and speculations about my problem, I was just about to give up my project when..... a good friend of mine asked to see my CHR-file... and when he checked the sprites they were all fucked up.. sort of! So for som reason I have managed to do something wrong when repeatin...

I have tried to put a SMB-hack onto a cart now... I have tried atleast 10 times, and every time I get graphical glitches, mostly vertical lines every inch or so across the screen, and sometomes also vertical ones...

But the PRG is 64kB and the CHR 16kB right?!

what´s wrong with the use of 27C256 for the CHR ROM and a 27C512 for the PRG ROM?!

Is it not possible to get them up and running?
