Pues con tanto con el Neo 2, como con el 2.2 y 2.5 por supuesto deben cargar DVDr (aparte de q ya ha comentado gente en el foro q le cargan), este es el método para cargar DVDr con el Neo2 q pone en liksang:
Using Neo 2.0/2.2
- Power up the PS2 and keep the power/reset button pressed to use the EA mode
( with the AR2 V2.xx Disc 1 already inside )
- When the AR2 finishes booting, just press the Eject button ( Keep the
power/reset button pressed, it's very important ) swap the original AR2 disc with
the original DVD PS2 disk ( with a really big toc, ex: GTA / DMC / DOA2 etc ) and
press the Eject bottom again, to close the tray!
- Wait 10 seconds!
- Make sure you have the "Dave Mirra Freestyle BMX2" Code selected before you proceed
- Select "Start game"
- With codes
- Press X
- A window with an error message will appear, release the power/reset button and the
PS2 tray will open automatically, just swap the DVD ( original with the big TOC )
for the DVDR backup and let the tray close ( don't forget the original DVD must be
bigger that the backup one, or it will not work )!
- Now press X to acknowledge the error message
- If you don't want to select codes (cheats) for the backup you want to run, just
skip the next step (*)
- (*) Press 'O' the number of times needed to get to the main menu!
After getting to the main menu, press "Action Replay Codes" and select the codes/game
associated to the backup you want to run.
- Press the key "Start" on the PS2 Joypad!
- Select "Without Codes" or (*) "With Codes" if you selected the codes for your backup.
- Press X !
- And it boots
PS: It was tested with V3/V4 and AR2 V2.00/2.02
), he probado 20.000 formas pero nada q los DVDr no los pude cargar con el boot dvd, se me queda en la pantalla del dvd region X, si no a ver como haces luego otro método EA una vez q has hecho doble swap y ya vas a meter el juego en DVDr...pilla un AR2 v2.02 q si q va tanto en V3 como V4 con el Neo2
