Unfortunately it did not work. Still have distorted screen on my games...
I thought it would be a good idea to upgrade for a PI3+ and get the latest update. I'm not sure anymore. (I need to fix that and also get rid of the Thunderbolt logo on the upper right of the screen. I raise voltage at 5.3V but still have that logo appearing randomly. I know Pi3+ need a little bit more power. I don't know if I can raise it up more, cause Pi3+ is suppose to need 5.2V. Didn't have any issue with Pi2.)
If you have any more idea, please let me know.
Your support, as always, is greatly appreciated.

Re: Image distorted on some games
How old is your board? Hearing it started with Pi2 makes me wonder if it doesn't have a 1A fuse in it, it would explain the trouble supplying power to a Pi3.
Assuming it is a 1A fuse replacing it with a 2A or 2.5A fuse should sort the lightning bolt and will make the board work better on newer RPis.
Modern JAMMA looms with only 1 wire each for 5v and GND can also cause low power conditions, however you will usually be OK for a Pi3, it's Pi4 where cheapo crappy looms start being a real issue for current delivery.
I wouldn't raise the 5v at your power supply any further. There's no need (or want) to go past 5.2v at the JAMMA edge, having to do so suggests it's another issue.

I bought the Jamma board from you on Aussie Arcade forum at the end of 2016. I didn't check the fuse but it's probably a 1A fuse, I will need to check this out. Since I did not saw any fuse holder, it might be welded on the board. So I will need to check out on Youtube for a tutorial to how replace that fuse...
...And the good news is that your latest REswitch.sh file did work! I did a mistake when replacing the file...I just put back the wrong Reswitch file on my SD Card...My bad...
