To Do:
- All games uses PORT_VBLANK and legacy screen parameters (which is already
bad per-se), with also naive and unlikely measurements (i.e. exactly 59.30).
The most blunt examples of something being wrong with timings are with
Gunbird and Tengai: they both have FOUR frames of input lag, the real thing
doesn't sport anything like that.
Given the above, all games are marked with MACHINE_IMPERFECT_TIMING until
somebody provides accurate H/Vsync signals for at least one game of this
driver.
- Some games use naive/unlikely measurements (exactly 59.30), which should be verified.
Tengai and Strikers 1945 have accurate measurements from PCB. Maybe these could be used
for other titles too?
- All games but Tengai / Strikers 1945 use IRQ1 for VBlank. This is likely incorrect.
On Tengai/Strikers 1945, its actually IPL2 that's asserted (Interrupt Level = 4).
- tengai / tengaij: "For use in Japan" screen is supposed to output the
typical blue Psikyo backdrop gradient instead of being pure black as it is
now;
