Removed TODO on uint32/int64 comparison type conversion because (#go_nuts) [23:28] <foobaz> it will not it is totally safe (and according to the spec, " When converting between integer types, if the value is a signed integer, it is sign extended to implicit infinite precision; otherwise it is zero extended. It is then truncated to fit in the result type's size. For example, if v := uint16(0x10F0), then uint32(int8(v)) == 0xFFFFFFF0. The conversion always yields a valid value; there is no indication of overflow. ", so only the source type matters)
Remove leftover TODO; filename_CHD is not part of Game.
Decided to just return the parent not found as an error
