The Xploder V4 Professional is nearing release and appears to be a carbon copy of the old Action Replay V2 software with the Game Accelerator feature added in, code encryption alterations and a few GUI changes
The save transferring feature is most likely the same used as the Xport which makes me wonder whether they will update or alter the format and whether it will feature compatabilty with the GTA games, a series only supported in the US version of the Xport.
If you do purchase an Xploder V4 Professional please do send me a save so I can take a look at it, tests with the GTA games would also be great as this is something people will want to know
