Setting up Mame / Mala with rotating CRT

Setting up Mame / Mala with rotating CRT

Hi. Please can I ask the simplest way of going about this?

My set up is as follows...

Mame 220

Mala 174

Win7 64

Semi auto rotating CRT.

The CRT rotates electrically with a one touch button. Touch the other button and it rotates back again. Once rotation starts both buttons are locked out until the rotation finishes. If power is cut during rotation then on re-powering either button can be activated to rotate to H or V. I want to keep it this way rather than have a prog control the rotation.

But what I also want is for Mala to stay in the rotated state of the last game played.

So, for example, if I am H, and I scroll through the Mala games list, and pick a V game, I want Mala to change the game to V, and I'll rotate the CRT with the button. When I exit that game I don't want Mala to go back to H. If I then select a H game, obviously I want Mala to give me the game in H, and I'll hit the button and rotate the CRT to H. When I exit that game I want Mala to stay H, and so on........

Can somebody please point me to where and what I set for this?

Thank you.

I've discovered BYOAC.

It turned out that I needed the help of some very clever people (well, one in particular... DaOld Man, over on BYOAC) who couldn't have been more helpful.

He wrote some plugin progs years ago when rotating was all the rage, and re-wrote one of them for my specific scenario, then gave me step by step instruction how to implement them.

All I needed to do then was to play with some simple electronics to interface the progs with the rotate mech.

I now have a Mame machine that automatically rotates the CRT and Mala depending on the game selected.

It's still WIP to complete the CPs but without the extremely generous help from DaOld Man this project would definitely have been shelved.
