That system is bad for Dolphin regardless of whether 64bit or 32bit, older or newer dev builds. You should upgrade Dolphin to the latest dev build AND upgrade your system or purchase a new system entirely if you can. You certainly won't be playing any games like the game you are trying to play on that system unless slideshows are your thing. According to his specifications op is using an old integrated chip that likely doesn't support the features Dolphin requires and likely still using Windows XP. Even if op had a proper save state from a 32bit, more accurately from the build that op is intending to use I doubt Dolphin would run on that system.
Also, shouldn't this be closed considering op is using an unsupported build and his/her system is too bad for Dolphin?
