**What was done:** ## Source
* All structures were populated, globals and locals named.
* All subs were decompiled, C pseudo code was converted to compilable C++. Loose (namespace?) subs were assigned to classes.

## On 64-bit bug that killed the game
**On 64-bit bug that killed the game:**\
I did not find it, decompiled game worked in x64 mode on the first try.\ I did not find it, decompiled game worked in x64 mode on the first try.\
It was either lost in decompilation or introduced in x64 port/not present in x86 build.\ It was either lost in decompilation or introduced in x64 port/not present in x86 build.\
Based on public description of the bug (no ball collision), I guess that the bug was in `TEdgeManager::TestGridBox` Based on public description of the bug (no ball collision), I guess that the bug was in `TEdgeManager::TestGridBox`
