This emu is getting better and better
Now with pcsx bundled in I can finally play other Tekkens than just the first one. Bad thing is that Tekken 3 (I only have 1 and 3) works unstable. Randomly it stucks in the window which is shown before fight should start and there's no way to make it continue from there. Emulator responses to the quit-button and returns to the gui.
Sometimes I can play the game for hours with no stucks.
Log shows nothing unusual.

Only config that I have found that I can launch the game:
core: pcsx
no bios
sound disabled

Both psx4m and psx4m-gles segfaults rightaway when launching.
