Open monitor (I use AR6 cartridge) and enter this in:

.a c000

LDA #$08
TAX
TAY
JSR $FFBA
LDA #$0F (*)
LDX #$00
LDY #$C1
JSR $FFBD
LDA #$00
TAX
TAY
JSR $FFD5
JMP $(next part address)


.a c100

00 00 00 00 00 00 00 00
00 00 00 00 00 00 00 00

filename data


(*) #$0F is the number of characters in the file to load.


Probably not the fastest loader as it uses the standard kernal routines, but it is a good start.
