The IL-2 Selector is a tool which enhances the memory management of the game "IL-2 Sturmovik 1946". The game is written in Java, running on a J2SE 1.3.1 JVM. The standard setting utilizes less than 128MB RAM only, which was fine when the game was developed initially, but nowadays patches and mods lead to a situation where more memory is necessary to smoothly run the game. This tool gives the user the ability to easily setup different memory parameters. Additionally it features an advanced so called "wrapper" to run modded files within the game's runtime file system. This wrapper runs several hundred times faster than the initial wrapper.dll release by QTim and thus enables the users to run even heavily modded game installations without any significant performance impact. Last but not least, for fine-tuning the JVM memory usage, this selector features a dll code injection mechanism into the running JVM. This project is released under the DWTFYWWI Public Domain License.
