Code DOS game BlockOut for browser with global ranking score website.

Hi. I want a DOS game called BlockOut as a online browser game with global ranking score website database. I want people to go to a website and there play the game from 1989 called BlockOut. The score they get, after a game, is to get uploaded to a server and get ranked on a global website server. So that when they restart the browser or computer , the score is still there and you keep your rank. There is a opoen source game you can download and in that you can upload your score. [login to view URL] So maybe it is possible to adjust that code to an online browser game? Can you help me? Regards
