Issues / To Do
--------------
- There is a 512 byte PROM in the video section (differs by game) that
controls the priorities. This prom is currently missing for one game,
so we have to use fake data for it (Chimera Beast).
- Making the M6295 status register return 0 fixes the music tempo in
avspirit, 64street, astyanax etc. but makes most of the effects in
hachoo disappear! Define SOUND_HACK to 0 to turn this hack off

bootleg version of rodlandj has one instruction patched out to do exactly
the same thing that we are doing (ignoring the 6295 status).
- Understand properly how irqs truly works, kazan / iganinju is (again) broken.
- Understand properly how irqs truly works, kazan / iganinju solution seems hacky
- 64street: player characters in attract mode doesn't move at all, protection?
they move on the real PCB
- tshingen: unemulated mosaic effect when killing enemies with the flashing sword.
See https://youtu.be/m4ZH0v8UqWs
The effect can be tested in e.g. stdragon and p47 test mode:
See https://youtu.be/zo3FTCqkNBc and https://youtu.be/dEqH017YBzw
- P47 intro effect is imperfect ( https://www.youtube.com/watch?v=eozZGcVspVw )
