If he wanted to play a cracked metal gear he wouldn't be looking for a computer now would he? 
By the way... I saw an MSX Turbo-R ST (very good Japanese MSX2+ system) bundled with a Metal Gear (1) on yahoo auctions japan. It has a few other games too, I guess you could sell those to earn back some money... The seller will not ship internationally, but I guess that he could change his mind if you offered him a couple of dollars more... As a sign of gratitude you could give me the "Illusion City" that comes with it I guess Current bid is around $160... I guess if you were to offer him $200 or $250 it would still be pretty cheap. My guess is you can sell off the other games that come with it (Except ofcourse the Illusion City 
) for at least $100. That would mean you're paying between $100 and $150 for an MSX Turbo-R plus an original Metal Gear. Not at all bad...
Mind you, there is no original Konami english Solid Snake. It's an incredibly cool translation hack.
I think my original post said I wouldn't care to have it in Japanese. I know there's no English version. 
Err... Mr. mje... You're 'free Turbo-R' chance is about to end. The auction ends today... I'd really try to at least contact the guy... The current bid on his lot is around $160... I didn't want to go into details, cause I'm sure someone here will probably jump at the offer, but he's selling for around $260,- (asking price without shipping)

Say you were to offer him his asking price, which no-one has done sofar, which is around $260. Just by selling off the games you don't really want (I assume) you will probably raise what you're paying the guy! And eventhough he doesn't ship internationally, I'm sure he'd go through the trouble for the extra $100. You'd basically get an MSX Turbo-R plus an original metal gear for free and would probably even cover most of the shipping and handling... I've heard of worse offers
