I have a pal sega saturn model 2 with a very stranger issue. I use pseudosaturn to play my backups. I think its a 21pin VA7. Some months ago i was playing DnD Shadows of mystaria suddenly after two hours of gameplay the screen goes black but its seems to lose the tv signal cause the AV sign appears on my tv. The audio continues although. After that i turned off the console, open it and it freezes on the saturn logo. The other day i put virtua fighter 2 and left it on for almost 4 hours to see if that is going to happen again but all it seems to be fine no issues at all! Yesterday i open the console to see if any of the capacitors could be damaged or it has leak but they seem fine too. So i put some games to play and when i put a capcom compilation disc the same happened again. The screen goes black and the music glitched. I reset it and it didn't freeze on the saturn logo and boot the game again to see if it was a bad rip but it played fine. I don't know what then problem could be. The AV port? the psu? The ntsc games cause they run on 60hz or maybe the cartridge slot?
The first time it happened as i played DnD Shadows over Mystaria and the yesterday when i play capcom generations (the Ghosts and goblins collection). Could this be a problem cause the games are NTSC and my console is Pal?
Capcom Generations do not use the cart, so I guess we can rule that out. I'd clean the cartridge pins regardless. Some NTSC games glitch up on PAL consoles but I don't know if Ghosts and Goblins is one of those. Xmen vs SF and Marvel vs SF definitely won't work though.
I'd recap the console. Saturns need those nowadays; just because the caps look fine does not mean they still work properly, electrolytic caps have a life span of 20-25 years.
