As you know Metal Gear (MSX) is on GOG for PC. It's the port added with Metal Gear Solid 3 : Subsistance. Which add infinite bandana and boss survival.

Should we consider it a new category or as an MSX category.

The port of MGX1 on PC is similar to the PS2 version of MGX1. There's already a run or two done on PC. It doesn't play anything like the MSX original.

Okay but where the PC version get submitted then ?. PS2 category ?

NTSC/HDC. Only PAL PS2 is separated.

This has been adjusted. GOG is now its own category!
