Hi everyone,
I have an odd situation. I have a CPS3 motherboard where the "TEST" button does not work at all - not from the jamma edge or the button on the motherboard itself.
I measured the voltage at +5v, and when the button is pressed, it goes low, however there is no action from the game.
I have a suspiscion it's similar to other 2929 chip issues where a button gets stuck (i.e. like this: https://www.arcade-projects.com/threads/cps3-p2-up-is-stuck-on.18068/)
Given this, I was wondering if it would be possible to create a Darksoft image where the test mode gets activated on boot... or through some other method besides the test button.
I could write the custom image, set my settings and save them, then rewrite the original image and play. I figure it's one of the two 64mbit program simms, right? I'm thinking I could save time by just rewriting that specific simm maybe?
Is this possible? I tried to look at the files in a hex editor myself but have no idea where to start. Also, if it's impossible or not feasible, at least the board works great with the default settings. Also open to any other ideas to try!
For reference, this is a custom SH-2 setup, but I also have a standard SH-2 if that makes any difference.
Thank you all
