TG/PCE Repair/Mod Discussion / Re: PC Engine Duo - Needs Angled to load games? (Potentiometer Adjustment)
« Last post by stridervm on November 26, 2025, 06:46:12 PM »
Any suggestion is better than going blind. I'll try to adjust it in the evening after work.

Anyway a question about adjusting the potentiometers. In the image from this site.

I assume this is set near the middle. Just turned a little bit counter-clockwise.

What should be a sensible range of adjustment? What I have been doing when adjusting is from the "middle" ,  turn the dial 5 degrees counterclockwise, then power on. If nothing changes, do it again, up to 45 degrees. Then reset it to the middle. Then go clockwise then.

I'm not an expert on this hardware; I'm just starting to research and learn about it. I don't know if you're experiencing the same issue as with the PlayStation 1 drives. There were usually two problems: a misaligned lens and discs that wobbled too much while spinning. On the CD-ROM2, I believe the VR102 potentiometer is responsible for correcting the focus height between the lens and the disc. I don't know if adjusting it will have any effect on your console. I'm sorry I can't be of more help; perhaps what I'm saying is nonsense.

TG/PCE Repair/Mod Discussion / PC Engine Duo - Needs Angled to load games? (Potentiometer Adjustment)

Hello noob here about basically everything about PC Engine.

Anyway I got this PC Engine Duo in a Japanese Auction for about $65. Hoping I would be able to be lucky to make it 100% working on burned CD games the same way for my PC Engine with IFU-30 CD-ROM.

I started blindly changing the dials (Bad idea I know) and somehow I got it partially working on some on the burned CD's I made.

However, the wierd thing is that the console needs to be crooked a little to the left in order to read the CD.



It cannot read any CD when the console is leveled to the table.



I wonder what could be causing this? Any suggestions?

After that crooked angle loading is solved when I will try to actually adjust the potentiometers again.

  I'll have to check out that music.

  I tried to play the NES version of the original, but the GUI feels too weird.  I'll probably end up playing the SNES Kyuuyaku version.

  Jack Bros. does seem interesting.  Kind of like Gauntlet.

Jack Bros was pretty fun on the virtual boy.  There wasn't exactly a wealth of great games to play on there.  I would say that of the whole library it was likely my second favorite after Wario Land.  I didn't find out it was part of the Megami Tensei series until many years later.

It was delivered to the apartment office, but my mailman is bad about leaving a note.  If I don't have tracking so I know it's there, I end up waiting for the office workers to bitch at me for not picking it up; they used to be open later, so it was easy to pop in and check, but now they're already closed when I get home.

I picked mine up Friday.  It's a sexy huey, and the cassette is pretty funky too.   :pcgs:

Okay good, you got it! I think I saw in Discord you saying that it wasn't delivered but the tracking apparently said it had already been delivered.

Replace the existing cable with an FFC connector and flat cable - look at how Tawy has done this on his replacement controller boards.
