Fix Flawed Segmented Addr Check

[MegaMech]

Not sure if I missed some but essentially:

(0x05000800 & 1) != true

This change needs to be checked against other ports as it might break them.

To give some history:

On N64, you had addresses that were direct pointers to RAM and addresses that were to segments. There were 16 segments, and the first byte of a four byte address would determine the segment number (00-0F). So for example, a segment address could be `0x02000040`, referencing offset `0x40` on segment `2`. On N64 it is easy to distinguish between segment addresses and regular RAM-addresses because RAM is mapped to `0x80000000` which is too high for segments. But on PC the whole address space is used, so a new solution had to be figured out.

Random figured that no pointers in memory should have odd numbers, that everything was at least 2-byte aligned. So if something isn't, the assumption is that it's a segment pointer and not an address into RAM. I guess under certain conditions those path strings do end up being on odd addresses, hence the need for the alignment macro.

Don't merge this, it's not correct yet.

It appears the issue is that I need to flip the endiannes of my n64 ptr:
0x0000000000080005

Resolved this issue by parsing the data at runtime and converting n64 ptrs to x86.
