Brandon Wright 756f370021 Go back to allowing writes to 4200 and vtimerpos to trigger immediately. 2018-06-02 18:44:13 -05:00
OV2 55cf0c287f Edge case when setting vtimer only on same scanline 2018-06-02 23:24:18 +02:00

Brandon Wright f70592df90 Don't use initial variable. 2018-06-01 15:05:58 -05:00
Brandon Wright 718f580342 This was wrong. 2018-06-01 14:19:59 -05:00
Brandon Wright 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.
