Juste the same fonts as in the standard skin, I didn't change anything.
As for other games crashing, it is possible because "other" games don't use VMM and a 720p/1080i buffer + background eats a lot of memory, 64Mb of RAM wasn't enough before, it is even more true here, you can see the menu crashing in 1080i too in neogeo mode, it's the same problem, there are no solutions for this (except a magic trick).
