Metal Gear 1 DynamicVsync patch v2

Answering the requests of the MSX community, sd_snatcher has improved the Metal Gear 1 DynamicVsync patch. New in this version:

• TAB: throttle game speed
• SPACE: speed up text dialogs, now works like Metal Gear 2 (the previous patch required you to alternate between pressing M and SPACE, which was awkward)
• Automatically sets the VDP to 60Hz at boot, to play the game at the correct speed, even on European machines. If you have an old European TV that doesn't support this, hold down SELECT during boot to disable this.
• Removed the annoying region lock. Now it's possible to play the Japanese version on non-Japanese machines
• Enhanced sprite cycling: if you have a fast MSX (like a turbo-R), the sprite cycling routine will take advantage of that and the flickering of sprites will occur at a higher frame rate.
• Improved graphics for the moving parts of the bridge. They now match the non-moving pieces better, resulting in a uniform visual.
