*OPT 1,2
*LOAD Chuckie 1100
The three big hex numbers it displays, in order, are <Load address> <Exec
address> <Length>.
Then it's a simple case of saving it with:
*SAVE Chuckie 1100 +<Length> <Exec address> <Load address>
For 'locked' files, running the following bit of code beforehand should
unlock loads:
P%=&900:[OPT2:PHA:LDA&3CA:AND#&FE:STA&3CA:PLA:JMP!&220:]:?&220=0:?&221=9:*FX1
4,4
