Subject	A couple of fixes...

Hi,

Here are a couple more small fixes, one is an i386 fix, the other for Neo Geo.

The first one is a fix for unaligned word and doubleword I/O reading and writing.  It makes 16 and 32-bit I/O accesses become effectively a set of 8-bit accesses, preventing accesses from being re-aligned to an incorrect I/O port.  This fixes issues in the FM-Towns where programs would set the palette by using MOV DX,FD92; OUT DX,EAX; (or similar) which would cause it to write to I/O ports 0xfd90-93, instead of 0xfd92-95 as it should.

The second is not so much of a fix, but as a convenience for the Neo Geo CD, by calling optimize_sprite_data() at VIDEO_RESET(), which will re-convert sprite data after it has been copied into RAM.  Otherwise, sprites will always be wrong.

Thanks,
Barry Rodewald
