9972e2df56 Change S9xInterlaceField to an inline function. 2023-03-07 14:01:29 -06:00

daf8fba09c Remove extra variables for interlace field. 
Keeping unsynchronized copies around is just asking for trouble.
Instead, use a macro to check the actual memory address.

f2b5f26a35 Move interlace flags to S9xSoftResetPPU. 
Windows is calling S9xGraphicsInit on BPP changes, and this
could reset the interlace interval.

718f580342 This was wrong. 2018-06-01 14:19:59 -05:00

14c8b043ef Actually, I like the other fix better. We know the HDMA reads this value into the MDR as an intermediary, not that writing the address writes to OpenBus. 
Revert "We definitely only know Speedy writes this address and it goes to open bus on hardware."

This reverts commit 6f5295225c.
