Subject: [PATCH] Decompile functions: sub_50F04, nullsub_20 sub_50DE8,
 sub_50DB8, sub_50B80, added variables and fixed currentpinballgame struct
 (#127)

* Decompiled sub_50F04, nullsub_20 sub_50DE8, sub_50DB8, and sub_50B80 added gUnknown_0200C668,gUnknown_0200EA58,gUnknown_0200BAE8,gUnknown_0200BBA0 to variables.h

* Correct PinballGame struct field at offset 0x1BC thanks to @Retn
Correct struct access in sub_50B80
Remove section .text50AD4 from linker script

* Deleted expected objects

* cleanup
