Version 1.1: NTSC bug fixed.

This is the SD2IEC enhanced version of my JiffyDOS mod for the Dolphin DOS kernal. Of course, it still works with any JiffyDOS drive nevertheless.
It is provided with no waranties whatsoever, so use it at your own risk. Furthermore, you need to legitimately own the JiffyDOS kernal for the C64 in order to use this patch.

A batch file is provided for your convenience. Just put your JiffyDOS image into the same directory where you have this patch and run the kernal_patch.bat. It uses the filename you'll get from the RETRO Innovations store. If you made an image of an actual ROM, your file has probably a different name. In that case, either change the bat file, or rename your rom file.

These features are the same as in my previously released S-Jiffy tailored version:
- You'll get all features of the Dolphin DOS kernal, except for the parallel speed routines.
- You'll get all JiffyDOS IEC bus speed routines in place of the Dolphin DOS turbo.
- The tv system detection is fixed to be turbo reliable.
- In direct mode, the loading addresses are displayed, unless you're loading with ",8,2". Dolphin DOS only did this when the parallel loader was in use. This mod does it with any drive.
- F3 and SHIFT-RUN/STOP don't clear the screen, but append a colon instead, so you can read the loading messages just in case.
- And since the JiffyDOS speed routines are smaller than the Dolphin DOS equivalents, there was room for some nice power up message, inspired by the C65.

These features are specially tailored for use with SD2IEC and thus differ from my previous release:
- F4: leave image / change to parent directory
- F8: change into image / sub directory 
- if a directory entry has its name shifted due to a 4 digit size, a space is automatically printed before the command in order to compensate for that.

Of course, the convenience has its little downside: You have no tape support (just like in JiffyDOS), and you also have no RS232 support (just like in Dolphin DOS).
