There is a torrent online with these same files in it:
*URL removed by Sprung* or do a search on *** for 'metal gear', it's listed as 'Metal_Gear_Solid(内附模拟器)' )
Just stop your download, rename the dl dir from 'Metal_Gear_Solid_NTCS_PSX' to 'Metal_Gear_Solid' and 'resume' the torrent with the above mentioned torrent file.
You can't just add the tracker url because it has an extra file in it (emulator?)
If anyone completes this, please seed the original torrent with the 2 files in it
Keep sites like that in PM's. ~Sprung
