Of particular interest to me:
Does it work?)
No.
"MultiSync + VGA Only" limited game audience? Perhaps a pre-game menu system to configure and adjust best-according for User.
Tested using a1200 setup for 72hz Productivity VGA, 68030@50 32MB, game is running but no visual. All monitor drivers installed.
Your visual parameters must be >15 <=29kHz. Hence Multisync AND VGA.
