klonoa

I found a bug on Klonoa 2 Lunatea's Veil that make the game crash when you finish a level and try to return on the level select screen. I use OPL 1.0.0 in case you need to know.

While looking through the Klonoa 2 manual, I noticed that there is a co-op mode of sorts, where the second controller can press Start to bring Popka out of the Ring, then Square to launch Klonoa. I was wondering if there was a way to map those two buttons to the unused buttons on the first...

I have problems with USA version of "Klonoa 2: Lunatea's Veil" on internal HDD. On OPL compatibility lists, I see that mode 2 must be turned on or mode 2, 3 and 6. But if I doing this, I still don't have SFX and game freezing after some time. Am I doing something wrong? OPL WIP-1554.
