Not only BASIC
Source file could also be an M/L code program launched by a BASIC stub!

Overview
This tool uses an undocumented (and probably never implemented before) exploit into LOAD command routine of KERNAL ROM, to auto-execute a program without the need of typing RUN, after the following command:

LOAD"file name",n,1

where 'n' is the device address, and '1' indicates that the file will be loaded into its own address memory.

Features

• Full navigable directory via up/down cursor keys;
• Editable boot message and target file name;
  
• Data buffer to reduce head seeking during disk access.
