Aquí esta el método, aún no lo he probado pero dicen que funciona por foros...
Ok for all of you out there who must reply on the knife-swap for booting titles on a version 5 ps2 and using the AR version v this is a fool proof method to boot everything (yes, even DVDr's).
1. Load AR2 V2
2. Select Action Replay Codes
3. Highlight Dave Mirra Freestyle BMX2 code
4. Press start
5. Press eject and insert original DVD (i use DSevil May Cry)
6. Wait about 10 seconds
7. Press 'x' on Withcodes, then 'x' again
8. Erros message appears 'Too many codes' (at this point you will hear the disk stop spinnin')
9. Now perform your tool/knife-swap trick for your CDR/DVDr
10. Press x to confirm the error message
11. Press circle twice to return to main menu
12. Goto 'Start Game', 'Without codes' - press x
13. Game boots.
Probadlo y decirme si funciona...los que tengais dvd-r y ar2, porque aún no me ha llegado el huevo de dvdr's que pedí
SUERTE!!! féliz año!!!
