Connor McLaughlin 2185bbec73 GPU: Display state in debug window 2020-05-17 14:11:42 +10:00
Connor McLaughlin 597aa20d83 GPU: Don't panic when FIFO is non-empty with VRAM->CPU copy
This probably is not a good state to be in though, since the DMA request
gets turned off and will never resume until it's copied out.

Connor McLaughlin 1757932b3a GPU: Implement FIFO and timings
This will cause a slight performance loss. I've left some knobs in which
can be tweaked to mitigate this, but the goal is to be compatible with
all games which require them.
2020-04-19 01:17:28 +10:00
Connor McLaughlin 7779a54bc5 GPU: Rename 'Force Progressive Scan' to 'Disable Interlacing'
It affects rendering as well as display/scanout now, after all.

Connor McLaughlin 3325d2c42c GPU: Add Force NTSC timings option
This option forces NTSC timings for PAL games, causing them to either
run faster (more likely) or smoother (less likely).
