Loading and saving to disk using kernel
Assume: Machine booted from cart. Cart ROM at $8000-$bfff. IO at $Dxxx and KERNAL at $e000-$ffff
What calls do I have to do to use KERNEL load/save?
What RAM and ZP will be trashed by this?
How will it affect my IRQs? (I have CIA1 and raster IRQs running via $0314/15) |

I could talk all day about the silly bugs I make. The file start and end addresses were set incorrectly.
I noticed some emulator differences: micro64 prints messages like "searching for", but Vice and Hox don't. |

You should not see any such differences - this is a kernal thing. You might have another bug - related to non initialized RAM (thats where the emulators differ). |

Thanks for the hint. MSGFLG ($9D) was the culprit. Fast loading in micro64 sets this to Direct Mode. |
