HyperSpin running at 2560x240 resolution

[alex_bb23]

I saw that the HyperSpin is displayed correctly at resolution 2560x240@60Hz and to be honest, the result is fantastic: no flickering, and you get lovely scan-lines with an arcade monitor on attract mode

The problem is shows up when you are running a game (with GroovyMame), the switch resolution is working but the aspect ratio is messed up because the image is tight in the middle. Of course, you can ease fix by modifying inside of mame.ini and change aspect auto with aspect 4:3 and almost everything go back to normal. The problem with this setup is that you get a small black border on the sides (left and right). It is not a big problem but I hope this can be fixed: maybe modifying the ”HFrontPorch” and “HBackPorch” or I’m wrong?

If somebody has a different opinion how to fix that, please let me know.

Thank you!
