PC-Engine Troubles [Solved]

[mimylovesjapan]

Hello everyone !
Someone could help me to resolve my compatibility issue with PC-Engine on OSSC ?
Some informations :
– OSSC with the last firmware.
– OSSC working perfectly with all my other game systems.
– PC-Engine : games on card (tried with R-type) : the PC-engine is starting at 60.05 or 60.01 Hz, then lose signal sometimes. After swaping many times the AV1, AV2, AV3, I can get 59.94Hz, and no problems during the game/
– PC-Engine CD-Rom : Here is the problem. Lot of games don’t want to stabilize Hz, they goes automaticly to 60.05 or 60.01 during the game, then lot of signal loose… I don’t know what to do.
-I use a PC engine modified in Japan by this store : https://page.auctions.yahoo.co.jp/jp/auction/d337601049
The site says this is a RGB, C-SYNC modification.
RGB cable was furnished with. It’s a japanese.
I wait for your help !

Quality of PC Engine RGB mods varies a lot unfortunately. It’s probably due to poor/outdated mod work, I had similar issues on PC Engines (on XRGB’s too) that were all fixed by just updating the mod.

Where should I start ? Opening the PC engine ? Or should I try a new cable first ? Or some settings on OSSC ?

Open the PC engine. Take a picture of the mod, making sure that component labels are legible. Post a link to the picture(s). We can tell you if the mod is outdated and/or shoddy mod work is to blame.

Dear NoAffinity,
Thank you very much for your response.
I opened a topic here about my problem :

You can find the pictures. They recommanded me to get a DuoRGB-X.

OK ! Problem solved by increasing Sync tolerance on OSSC board !
Thank you everyone !
