the best program, seems to be what most r using and I use is DVD Decrypter(free progy) thats what I use to copy and burn the games. You might need CDLoader to run some of the games. Do you currently have any backed up games? How do you run them now. heres how I run mine, with a different chip. Gonna put in some info from a different post.
have a V4 PS2 with a neo mod chip soldered in.
1. Eject the cd tray
2. Put in the Gameshark PS2 disc.
3. Reset (press the power once)
4. Start game with out codes
5. Put in CD Loader (burnt on cd-r)
6. Let it run, then put in an original DVD game. (I used GT3.
7. Press x, CD Load will say put in a dvd-r game. Swap the disc either with a flip top( a modified case that you buy) or make a slide card(there is links to the diagram for that in the forum)
8. Press X and play.
Make sure you use DVD Decrypter to copy and burn the dvd game. Burn at 1x and read and write in ISO mode using default settings except for 1x write.
Thanks Devilhunt for the help.
This is just information that I posted in another thread for someone. thought it might be usefull for everyone.
I don't think you need a mod chip to play them. However you do need SwapMagic (which you purchase, search in google, I've seen it bundled with a slidecard) Which is the second item you need. its a a piece of plastic that you make or purchased with SM. it allows you to unlock the cd tray and eject it without pressing the eject button. Not all games work with SM, however there is fixes for those at http://www.swapmagicfix.com There is also a fliptop (like the psx console) that you can buy which allows you to open and swap discs, without having to use the slidecard(plastic tool)
To Copy them download DVD Decrypter, its a free program made to copy cd's and dvd's of all kinda. When you get it and copy. Go up to mode and select ISO-->Read to copy and ISO-->Write to burn. Burn at 1x or slowest possible. Default settings for DVD Decrypter is all I use. Meaning I don't touch anyother settings.
There are modchips out there. I as lucky and had it bought and installed by a friend for $50 total. There is also no solder modchips as well which you could put in. however you loseyour warranty and so on. Didn't bother me much cuz its probably only a year anyways. seems to me that it is easier to get SwapMagaic(purchase), Fliptop(purchase) and cdloader(free download). But like I said you can do without the fliptop. I don't have it, its a little harder to swap but you only have to do it when you run the game, after that its hours of play. Depends on your financial situation. The fliptop is cool and I will probably buy one someday, just for the look and ease. But not needed
