Last Ninja’s graphic engine bug identified

I finally identified the bug in LN that causes differences in the way I produce C64 hires pictures in I2012 and LN itself πŸ™‚

As the bug is caused by a wrong destination address in a conditional branch instruction, I think I should provide a fix for the bug instead of simulating the bug in I2012 πŸ™‚
