 You may have remembered back in the 1980's / 1990's C64 scene groups liked to present their own productions by adding a de-crunch 1-liner to your own programs. A lot of these were made in Cruel Crunch or Power Crunch. Nowadays, for speed and efficiency the majority of us have moved to cross-platform coding. We know how much of a boring process crunching has been. Some of us still miss the decrunch text method. You may have remembered back in the 1980's / 1990's C64 scene groups liked to present their own productions by adding a de-crunch 1-liner to your own programs.

-Exomizer has a custom de-crunch effect routine, when using SFX mode. Its default effect is a flashing character at the bottom right of the screen. There are possibilities of customizing exomizer to do really cool de-crunch effects based on the old packers/crunchers you may have used. For example, here is an example of the [b]Speed Packer V1.1[/b] decrunch sound: +Exomizer has a custom de-crunch effect routine, when using SFX mode.
