The full story is in oldest to newest chronological order below, but the tldr is that my Japanese 3DO has issues after 15 minutes or so regardless of the game (I initially thought it was limited to Road Rash, but that isn't the case). I replaced the 2 common problem caps (C35 & C36), I removed the factory power supply and did a USB-C swap, and I installed a 20V fan in the factory location (Japanese units didn't come with fans). I've even tried removing RF shielding and running with the top removed, but nothing seemed to help.

Then, for fun, I pointed a pedestal fan right at it with the top removed, and wouldn't you know it I can play for hours on end now. I let it overheat again, and used my laser temp gun to read temps of every component on the main board and everything I could get line of sight to in the CD drive, but the hottest thing I found was only 120* F.

At this point I'm at a loss. Is it worth it to try replacing the rest of the caps? Find a replacement disc drive?

I bought my original Odin shortly after they were released, and I set it up with Retroarch and Daijisho. It worked well at the time. I haven't used it at all since though, so my memory on how everything is setup is very rusty.

I believe I have all of the cores loaded that I want (nothing even as new as a PS1). I have the platforms I want loaded in Daijisho, and it appears as if each platform is connected to the proper core (as seen on the bar on the bottom of the screen. When trying to load a game, it will always boots the last game played instead of the game that I selected. However, when I select a game in Retroarch it loads properly. I've reinstalled Daijisho, but that didn't fix the issue.

What am I doing wrong?

I had previously posted about what I thought was an issue with my Road Rash, but after I bought a 2nd copy, and played around with some other games, I'm pretty sure the console itself is having the issue.

I bought a cap kit for it, but I'm not great at soldering and after reading how hard it is to do, I'm hesitant. I haven't looked at the boards to see if the caps are leaking.

I'm wondering if I should start with a power supply as it is a Japanese console running on US power. Does that sounds like the best plan, or should I look into capping it?

For context, my set is a 27" Toshiba CRT. To that I have hooked up an NES, SNES, N64, GameCube, Genesis/CD/32X, Saturn, Dreamcast, 3DO, original Xbox, PS1, and PS2. I'm not even sure which, if not all, of those have gun games I'd want to get but I'm pretty sure the majority do. My question is does anyone make a light gun that works on more than one of those? Or is there an adapter that allows the use of a gun across platforms? Just trying to avoid having to buy a bunch of different ones if possible, but I realize that probably is the answer. TIA!

Not sure if that's just the way they are, or if they're just weak on ours, but you can barely tell that they are on. Can other owners chime in if theirs are the same? TIA!
