Memory Ceiling to Older Apps/Games

[CrimsonKnight13]

I have a few older games that I'd like to limit the amount of memory that can be seen by them. I don't want to set the ceiling system wide but would like an application for this. Are there any such apps out there & what would be recommended? Thanks in advance for any positive replies.

Note: This is for my 8GB desktop system. Currently no issues with my 4GB laptop though.
