How to boot a dvd+r backup

[pjclark1]

i have never managed to boot a dvd-r game using
an action replay 2 and a no solder mod chip.
(and i been trying for 6 months)

Just got a swap magic 2 boot disk
easy.....boot with swap magic 2 dvd boot disk
exchange for backup dvd-r when it says (swap trick)
press x and play game....about 15 seconds in all.

no mucking around with original dvd game..no double swap...
ps
allegedly only 1 in 10 PS2s will read dvd+r
(why on earth did you buy one of those)
