JEmu2's Development blog

Working on improving the V9938 instruction set emulation is starting to show results. Next release, JEmu2 will be running a game which is often touted as the best MSX2 game ever: Metal Gear 2: Solid Snake. And it now finally works perfectly!

People who know this game often regard the game Metal Gear Solid, which first appeared on the PlayStation, as a 3D remake in terms of story, events and gameplay.
Metal Gear 2: Solid Snake game is quite unique in the sense that it is the only 'real' successor of the first Metal Gear game, and the MSX2 was the only platform it has been released on (the first Metal Gear game has been developed and released first on MSX2 as well).
There has been been a Metal Gear 2 released for the NES, but the original game designers were not involved in that and the game turned out as a real disappointment, sharing none of the qualities of the successful first Metal Gear. Even the story has no connection with the Metal Gear saga whatsoever.

Fortunately, an official Metal Gear 2 was made by the original designers from the first Metal Gear, the still very successful Hideo Kojima being the most important, and this version was not only a worthy successor but a fantastic game in its own right as well.
The only downside of the official Metal Gear 2: Solid Snake was that it exclusively appeared on the MSX2 (a system which was only successful in a few countries), and it was also only released in Japan, so difficult to understand by people who don't understand japanese, if they could even get a hold of this game in the first place.
Fortunately, Metal Gear 2: Solid Snake has later been translated to English by fans (so it's not an official translation), and this is the version which will appear on gagaplay.com. Now finally everyone can see what a wonderful game Konami has kept from non-japanese and non-MSX2 users.

There will be a few more games in the next release of JEmu2, such as Arkanoid 2: Revenge of Doh and Contra (a.k.a. Gryzor).
