Here's a small excerpt from my Menu Load: ldy #number_of_chars_to_type_in sty $c6 loop: lda table_of_chars_to_type_in,y sta $0276,y dey bne $loop jmp $e386 table_of_chars_to_type_in: .db $9B, $93, $52, $55, $4E, $0D ; Turns cursor color to light grey, clears the screen, enters "RUN" and presses Return. number_of_chars_to_type_in = * - table_of_chars_to_type_in (This is a manual disassembly, as it never had a textual source, so syntax errors are well possible.)

Make sure end of program pointers ($2d/$2e) and eventually last loaded byte pointer ($ae/$af) are set to the real end of the program+1 once has been moved, many unpackers rely on them to know how to unpack. for example, if program fills $0801-$9000 inclusive lda #<$9001 ldx #>$9001 sta $2d sta $ae stx $2c stx $af jsr $A659 jsr $A533 jmp $A7AE no need to print or stuff anything. -- -=[]=--- iAN CooG/HVSC & C64Intros ---=[]=- Linking error. Your mistake is now in every file.
