True, with final burn it gives a lot of problems due to the vertical configuration, it’s crazy to put everything right once you have loaded the shader.
With Mame it is the best but the problem is that if you touch the configuration in the vertical version the horizontal is also modified, also with my vertical versions I cannot use the graphics of the controls of the horizontal versions because they are outside the cabinet.
I am one of those who has thousands of games in Mame but it is not a problem, the horizontal version is simply applied to the desired core and then if you load a vertical game you apply the vertical shader and save the settings only for that game, It is not a problem.
By the way I am going to do it for Mame and Final Burn but I have also been trying to do it for Cps1, Cps2, Cps3 … including making companies and making one for Capcom, another for Konami, for Sega, for Namco. … I don’t know, that’s what I’m thinking.
I leave a premature version of Capcom’s CPS2 board.
