Saturn or PAR 4MB Cart problem?

[Bloodreign]

I have a set of known good Super Adventure Rockman discs that boot fine in an emu and have no visible damage. THey boot intermittently with my Pro Action replay Plus in my Saturn when other discs work fine. I am trying to determine if the problem lies with the PAR or the Saturn lens as the discs are obviously not the problem.

Tried with Pulirula as well, the game seems to get stuck on the Now Loading screen and that disc runs fine as well in an emulator, it also ran fine on my first playthrough of the game.


Could it be a Saturn laser lens problem , or should I invest in another PAR? I've had the PAR cart for about 2 years now, and lord knows how old that cart was when I got it off ebay.


Edit: The Taito games I have seem to now run fine with the Saurn and the Action Replay Plus 4MB cart, but SAR refuses to run anymore at all, again the Super Adventure Island Rockman games run fine via SSF emulation. Perhaps Super Adventure Rockman is one of those games that will not work with a PAR, but only with a Japanese Saturn (I knew of only one game that I read about long ago that did this, it wasn't SAR, but I remember it being a shooter), weird thing is SAR fired up the first time I tried it out, but wouldn't run on the Saturn again afterwards, all 3 discs were tested and all 3 wwere in working order.

Definetly an oddity.
