How does it pack the PS-EXE to gain additional room to add additional code for hooks, etc? It can't work with every game. I'm sure it causes some to crash.

This tool pack the exe to reduce is size for adding cracktro for example. A code in the cracktro depack the exe after for launch the game usually. This tool work great and is usefull because exe+cracktro must have same size of original exe to be insert in the game another tool can be combined with another tool

Unused kernel space is used to embed a hook.

yes it could be happen. sometimes we had PS1 Exe Files, they were too small and packing was useless. in this case it is not possible to add music or gfx or something like this (because the final filesize MUST not exceed the original Filesize of the non packed Sles or Slus exe --> if exceeded, the whole Game does not boot and run the game).

if you have only 10kb free space after packing, you can add the values for pal and ntsc and a fontprint command, thats it.

In Alien Resurrection we had this example. the original Slus file was around 30 KB. No room for the trainer or something like a stylish cracktro.

But: Alien Resurrection contain more than 1 Exe File. I decided to add the Trainer and the cracktro in the 2nd Exe File and after packing, i had enuff space to add all needs + gfx + sfx.
The game start normally and after loading the game, the Trainer shows up with the Cracktro ;)

How many trainers have already done(82), nothing has crashed so far. Where necessary I use additional compression.
