That sounds greatXtraSmiley wrote:I have two Knuckle Bash PCBs (Japanes and Korean) and a Snow Bros. 2 on the way from overseas. I'd be happy to test, but I'd need some info on what you're looking for exactly. As I posted before, I think my Outzone works with my HAS to an OSSC... but maybe I was crazy before.
Simply check if you can get a stable picture with the OSSC on default settings. If not, try increasing H.samplerate very liberally (1000+) and see if you can get an (intermittent) picture this way.
The latter would mean that the game has the Sync glitch responsible for the OSSC incompatibility. In addition, it would confirm the aforementioned thesis.
If you have an oscilloscope, you can ensure that it's indeed the problem discussed here by measuring the Csync signal. Look for the Vblank area and measure the period p1-5 as shown in this image: click
Results for Knuckle Bash and Snow Bros. 2 would be interesting, I don't think the difference between the Japanese and Korean version of Knuckle Bash should matter, but you can of course try both if you wish.
No need for examining Out Zone as that's Toaplan V1 hardware. These games all work with the OSSC as far as I have seen!
