In the core.ini you add the following:
[ Replay ]
ReplayMemoryOverride = 131072
The value is in Kb, so increase it if you want gpl to use more, decrease
it if you want to use less (unlikely with 1Gb RAM).
Windows 98 has a separate issue where it can only cache up to 512Mb RAM
and any extra will actually cause a noticeable performance drop
apparently.
I believe the way round this is to add the following line to your
system.ini:
[vcache]
MaxFileCache=524288
I've never had more than 512Mb though so I've never used it myself, and I
think it limits win98 to 512Mb, making the extra RAM useless unless you
have a dual boot system with another OS (win2k/XP etc) that can use the
extra RAM.
