Hello,
I wanted to play The Guardian Legend and so I was browsing romhacking.net to see if some improvement hacks esisted... and I found this one
https://www.romhacking.net/hacks/3734/
The problem is that, after patching, the graphics are all messed up (from what I see patching changes the game mapper to MMC3, but it should be implemented, right?). It is not a big deal (I can play with passwords anyway) but I was curious to know if I did something wrong or if there is a problem with the nes core and this particular hack.

Thank you very much!

This MMC3 hack doesn't set the CHR bank registers so it only works on some emulators. It needs to be patched.
