this has nothing to do with exult. It's a patch to make the original U7 BG and SI in windows. The main patch only works in win 9x. There is another version, NT compatible, but it's much slower.

The guy also gives some interresting memory "managers", which I sadly can't test at the moment because I only have ntfs partitions (and I'm too lazy to create a fat32 one 😉).

You'll find more info about these mem tools here:

These too are sadly "chipset sensistive". But maybe the older ones (in the umbpci page) could work with AMD processors??
