Its Original MSX2 version or GOG messed up with screenshots and it's just DOS version?

Just started it and it is the MSX version but it looks like it's based on a release from one of the collector's editions they have released in the past.

Controls are OK? Can be played with gamepad or keyboard only?

Main page says controller support so gmae pad or keyboard.

It's based on Subsistence version or similar post-MGS3 version, which have additional features and translation. I didn't play Subsistence version very much, but I can tell there's worse framerate than emulated MSX original version and some guards have different positions. Still not sure which version I prefer the most.

So far I can use keyboard and dinput controller. Everything's fine.

does anyone know how to get metal gear to run right on windows 10?
possible compatability setting issues.

Is a native port or a MSX rom running in an emulator?

idk i just downloaded it off of gog galaxy..

NES version have Metal Gear only in name, original have it in person. So pretty much everything is better about original version over NES.

Thanks for the answer.

Yeah, I don't know what's the deal with the framerate, the Subsistence port already suffered from this (While the MG2 port on the other hand played way better than the original MSX version.) but the enemy placements are sort of an improvement. The big difference is that the original MSX version had more areas that you straight up couldn't enter without causing an alert, often one that you could simply escape by moving to a different screen. Not a big deal in the OG version, but since they added a ranking system to the Subsistence version, i.e. at the end of the game you get ranked for how few enemies you killed, how few alarms you've raised, number of deaths, saves, playtime etc., they went and reduced the amount of mandatory alarms in the game. There still are a few alarms you can't get around, I think there are, like 3 or 4, but that's about it.

DIdn't know they added ranking system, thanks. Can't say I like how guards was placed in trucks like that one with keycard 1.

In original when you enter, guard will immediately spotted. What you need to do is simply wait outside for guard to exit the truck. In this version when you enter, guard patrolling to the left, so you are free to sneak around and deal with him no problem. May be it was made in such way to accommodate new ranking system, but I feel it diminished some experiences in the process.

One other thing I don't remember in Subsistence was a siren sound when spotted by camera. For some reason in current port, siren sounds only once, then quiet alert theme starts to play, but after a few seconds it abruptly restarts with normal volume. In original siren repeated four times before alert theme starts. A bug? Or it was like that back in MGS3 port?

The controls using a gamepad are broken. Only analog stick works, and even then, it only goes up and right. D-pad doesn't work at all. Whatever the "use" button is supposed to be ('C' using the keyboard), doesn't seem assigned a button at all

This version is ok for a (pre smartphone) cellphone game ported to playstation 2, ported to pc. Just be warned that it has extra crust compared to the original or NES versions. The movement is choppier and the sound is a little off.
