|
| Thu, 27 Apr 2017 23:08:49 -0700 |
Michael Pavone |
Fixes to sprite phase 2 so that sprite X reads use the exact same slot as on hardware in the case that there are fewer than the max number of sprites on each line. Re-read sprite Y from SAT cache during phase 2 and properly mask the calculated row. Fixes remaining issues with spinning cube scene in Overdrive 2.
|
| Wed, 26 Apr 2017 22:16:12 -0700 |

|
| Fri, 21 Apr 2017 01:22:52 -0700 |
Michael Pavone |
Fairly major rework of how active/passive is handled along with how the V30 mode bit is handled. Allows the vertical border extension trick in Overdrive 2 to work right
|
| Tue, 18 Apr 2017 19:27:10 -0700 |

Somewhat broken implementation of Mode 4
|
| Thu, 22 Dec 2016 19:51:25 -0800 |

Clean up symbol visiblity and delete a ltitle bit of dead code
|
| Mon, 22 Aug 2016 09:46:18 -0700 |

Fix GST savestate loading to deal with SAT cache to fix sprite corruption on savestate load. Clear out Z80 native_pc so the Z80 state does not get hosed when loading a savestate while the emulator is already running
|
| Sat, 30 Apr 2016 15:31:48 -0700 |
Michael Pavone |
Implement SAT cache. Causes some graphical corruption in Overdrive due to an unrelated bug.
|
| Sun, 24 Apr 2016 01:24:38 -0700 |

Implemented VDP read prefetch and made DMA copy not use the FIFO any more. Now up to 114 out of 122 passing on VDP FIFO Test ROM
|
| Tue, 12 Apr 2016 21:38:24 -0700 |

Remove the int number argument to vdp_int_ack since it is no longer used
|
| Thu, 28 Jan 2016 09:10:14 -0800 |
Michael Pavone |
Shift slot number to slot behavior mapping by six slots in H40 mode. This makes the line change slot align with the point at which the display turns on and off at the end of the active display area. Also fixed a regression in which an external slot got accidentally changed into a sprite draw slot
|

|
| Sat, 16 May 2015 23:04:57 -0700 |

First pass at emulating a vscroll latch. Titan's Overdrive demo seems to depend on the scroll value being latched early in the line before the HINT gets a chance to change it

Fix most of the breakage caused by the vcounter/hcounter changes
|
| Tue, 17 Jun 2014 19:01:01 -0700 |
Michael Pavone |
Partially working switch to having a vcounter and hslot counter in the context rather than trying to derive them from the cycle count. This should allow for more accurate handling of mid screen mode switches. Interrupt timing is broken currently though

Fix DMA fill so that it does not cause observable changes to the FIFO. Get DMA copy mostly correct from an observable ffect perspective. DMA copy probably does not reflect internal implementation still given that evidence seems to suggest no FIFO usage at all.
|
| Sun, 15 Sep 2013 22:20:43 -0700 |
