Inspired by Matt Osborn and others' work on SMB1/Excitebike, I decided I wanted to make a hack for my Vs. Gradius which would allow the attract mode to work during free play. I've hacked something together which works in Mesen, but I am hoping to find some beta testers who have both: (1) a Vs. Gradius board and (2) a ROM burner so they can burn a custom ROM of the game.
I don't have a burner so I unfortunately have no way to test on real hardware, but I'm hoping I can find some help here.
Send a DM if you're interested. This isn't a high score save hack, just adds freeplay attract mode. For now the hack pretty much assumes you're gonna keep your cabinet in free play mode, so other dip settings will cease to work. I could probably improve it a bit to make it mostly function with normal dip settings, though the "insert coin" text has been replaced with "free play" which will affect all modes.
Hope some people find this useful. As a recent red tent acquirer, I've been obsessing over it and I'd love to get all my games to work with attract mode + freeplay, so the cabinet looks more interesting while its powered on and also to avoid burn-in on the monitors. Once I'm finished with Gradius I plan to move to Dr. Mario, then hopefully Tennis and Balloon Fight (though I'm not sure how much extra effort the dual screen games will be, I'm curious to find out...).
