I've got a Neo Geo CD (toploader) which is running about a 1.5 year now and it is being used on a weekly basis.
The system was always stable and we play in fact the same game over and over (Puzzle Bobble), the CD hardly leaves the tray.
But since last week spontaneous resets during gameplay are happening after +- 30 minutes when the NGCD was turned on.
After that it happens more frequent like 15 minutes.
I read a lot about lens issues and resets, but this doesn't seems to be the case as Puzzle bobble is loaded entirely in memory (so no loading in between sessions).
It seems to happen in 2 player mode a bit more frequent than single player mode.
I've tried several other games, to analyse the issue like Pulstar (did not happen within 1 hour).
With Fatal Fury 3 within 30 mins also resets.
It always happens in the "heath of the moment" when playing, battling, but never during loading.
I've tried original CD's and "backup" CD's, but all the same behavior. Up until now the resets never happened during loading, that is why I don't think there is a lens/laser issue. I can also clearly see the red laser.
I've also swapped the power supply POWCD-E with a POWCD-J using a stepdown, but the resets are the same with both. So I don't think the power supply is an issue here.
The machine was running fine for over a year, did not touch anything in the setup and now it occurs with almost every game session.
What could cause these resets?
