- The SRAM test fails in diagnostics; this is due to the fact that the test
relies on executing out of the cache while it tromps over (and eventually
restores) the instructions it is executing; this will likely never be fixed.
- Bootup sequence (the blue color fill) is too fast, which in turn causes
attract mode music not to play. Maybe the main CPU is running at a lower
clockspeed at boot (50MHz/4 seems plausible), but then, what toggles it?
- Screen timing (not just H and V freq). 261 lines should be good, but pixel
clock is unknown. The only one that comes close to sensible values is 6MHz,
yet there is no (multiple of) 6MHz XTAL.
15384.6 / 58.9634 = 260.9178 (261 lines? howcome it's off by 0.1?)
15384.6 * 325 = 4999995 (nope, 5 clocks hblank/hsync is too short)
15384.6 * 390 = 5999994
