PC-FX Localization for Team Innocent is released, a pre-Christmas gift!! In a twist, it feels like the NEC PC-FX got more attention in 2024 than any other time I can remember! Caveat: The localizers consider the "v0.9" patch a BETA as it still faces technical hurdles to eventually subtitle the FMV scenes, but they consider it very much playable. |

In most cases you have an opamp that is pegged (output pins near supply voltage or ground)

Ok the system has 3 sound sources
Chiptunes from the 6280 covers all card based audio
It's stereo
PCM audio used for high compression audio, often during movie scenes (depends on the game)
And CD audio (basic CD player sound from a DAC chip)
The 3 run through resistor/amp mixers

I'll let @thesteve know, if not @Keith Courage, the two main PC Engine repair guys that are reachable.

Console Repair/Mod Center / PC Engine Duo - bad sound (rec...
Last post by Reminiz - 07/06/2026, 11:59 PM
Hey everyone,
I recently recapped my entire Duo due to not having good sound or almost no sound from the console. It had also previously been RGB modded using doujindance's RGB amp mod.
Image looks amazing with SCART cable, same one used on Pc Engine CoreGrafx with no issues (sound n video great).
The sound issue:
- Full loud music through left speaker
- Only effects sounds from right speaker
I used console5 recap kit, so 50 odd caps have been replaced.
I've checked voltages on the IC506 and all sound I/O is 3.8V also checked C622 and that seems to be correct voltage.
Anything else I need to check?
Could it be as simple as dirty vias near/under the IC506?
Things to note:
- IC506 Pad 5 was torn so I made a jumper from a discarded TH cap leg from pin 3 to pin 5. Also ground pin 4 wasn't grounded so jumpered to the ground space next to it.
Could my IC506 simply just be toast? I did apply some heat near there so perhaps it got scorched?

PC-FX Discussion / Shattered Decks - PC-FX Homebr...
Last post by gameblabla - 06/28/2026, 01:00 PM
A new homebrew game for the NEC PC-FX that i've been working for a while.
It's a card game inspired by Forbidden Memories with a story mode with 5 duels, 70+ cards, a random battle mode.
The story follows Serena through a desert dreamscape of forgotten courts, sanctums, mirages, gates, and burning ruins.
She must fight through 5 hardened duelists with her deck and close the Gate Beneath the Sands.
It features a 3D software rasterizer for the field and touches pretty much every aspect of the PC-FX :
RAINBOW
2D backgrounds during story mode, drawn behind KING.
KING
3D Rasterizer draws to an 8bpp surface ingame. Titlescreen/Ending uses YUV422 mode instead.
Save support
Saves to internal and FX-BMP for saving your progress as well (the first PC-FX homebrew game to do so)

Console Repair/Mod Center / PC Engine duo drive issue
Last post by ModInFrance - 06/22/2026, 02:23 PM
Hey team,
I've just finished recapping a Duo. A bit of leakage but nothing too bad.
However the Drive is still failing
The disk spins, the lens move vertically. I hear Clic, Clic, Clic and it stops turning.
Video here :Am I good for a drive change or is there any chance I can fix it?
Thanks

Console Repair/Mod Center / Turbonanza PC Engine Mod High-...
Last post by MaRC - 05/29/2026, 06:54 AM
I have several PC Engine consoles—CoreGrafx 1 and 2—and installing Turbonanza requires cutting the metal shield that holds the spring-loaded balls. I didn't like this, so I redesigned the board for installation in the PC Engine. Everything remained essentially the same, but I removed the components responsible for Svideo. I output the image and audio to a replaced DIN9 connector, removing the resistors connecting the original audio to the connector. Everything works fine, the image has minimal banding, but high-frequency noise has appeared in the audio. It's independent of what's happening on the screen, it's not interference from the video. I use a very high-quality cable with shielded wires. If you re-solder the original audio, the high-frequency noise disappears. Is this a flaw in the original mod? Did I mess something up when redesigning it? Or is this noise coming from the additional channel the mod mixes with the main channels? When I get home, I'll try measuring the noise frequency with an oscilloscope.

Hey gameblabla, good to cya around here again sharing some content! Thanks!
Even less PC-FX fans around, but might as well for google search results to spread the word in case someone sees it!
