FIVE BYTES by viznut/pwp
(or seven bytes if you count the prg header)
(7e 00) 3e 10 8f e8 50
These bytes inject into the RAM-resident CHRGET routine as follows:
original new
0073 inc $7a
0075 bne $0079
0077 inc $7b
0079 lda xxxx
007c cmp #$3a
007e bcs $008a 007e 3e 10 8f rol $8f10,x
0080 cmp #$20 0081 e8 inx
0082 beq $0073 0082 50 bvc $0073
To generate the prg file from a unix shell:
echo fgA+EI/oUA== | base64 -d > fivebytes.prg
To write the bytes in vice monitor:
>7e 3e 10 8f e8 50
g
On the C-64 you can try: (7e 00) 7e 00 d4 ca 50
