OK, so I got Tetris Grand Master up and running. Here's what I had to do that's out of the ordinary: I used the Windows Games shortcut (*.lnk) method to run these and give them a name that looks prettier. I had to set the Advanced Config to watch the process (game.exe) so it didn't lose focus and fall back to GameEx (since it launches game.bat which in turn launches the game). Since I know these games are made for XP, I also set up "Compatibility Mode" to use XP SP3 on the game.exe. For some reason, the game didn't want to load unless I hit [ESC] first. So I added a SendKeys command to hit [ESC] for me after 2000 MS. Finally I had to change "Show Desktop" to "True". After remapping my keys through the loader, and setting up an xpadder profile (in this case I even set it up to use a 4-way joystick since that's what the original game uses), all works well now. I haven't attempted vertical games yet, I wanna nail the horizontal ones first before I move on.
