| 111 | 111 | Source Changes |
| 112 | 112 | -------------- |
| 113 | | -Huge effort has been done in order to modernize core and drivers, almost |
| 114 | | every file have been touched [Curt Coder, Osso, Alex Jackson, smf, Miodrag Milanovic] |
| 113 | -Massive architectural change: There is no longer a single, global palette. |
| 114 | Instead, palettes are now devices, and drivers and devices can have as many |
| 115 | independent palettes as needed. This update required extensive changes to many |
| 116 | parts of the core, UI, OSD layers, drivers and devices. [Aaron Giles, Miodrag Milanovic, Alex Jackson] |
| 115 | 117 | |
| 118 | -Likewise, there is no longer a single, global array of decoded graphics. |
| 119 | Decoded graphics are now owned by devices using a new device interface, |
| 120 | called, unsurprisingly, device_gfx_interface. A "gfxdecode" device (which |
| 121 | does nothing but inherit this interface) provides the old, driver-level |
| 122 | decoding functionality for drivers with video emulation not based on devices |
| 123 | and for devices that haven't been updated to the new interface (which is |
| 124 | currently most of them). Also, graphics layouts can now reference shared RAM |
| 125 | regions by tag the same way as ROM regions, eliminating the need to set up |
| 126 | RAM-based graphics manually (note that drivers/devices are still responsible |
| 127 | for marking gfx elements dirty when the RAM they are decoded from is written |
| 128 | to) [Miodrag Milanovic, Alex Jackson] |

| 131 | every file has been touched [Curt Coder, Osso, Alex Jackson, smf, Miodrag Milanovic] |

| 564 | 581 | |
| 565 | | -Stop the flipping insanity [Alex Jackson] |
| 566 | | |
| 582 | -Stop the flipping insanity: [Alex Jackson] |
| 567 | 583 | Tilemap flipping is now calculated relative to the center of the |
| 568 | 584 | visible area rather than to the total screen size, and the generic |
| 569 | | flip screen functions no longer reconfigure the actual screen. These |
| 585 | flip screen functions no longer modify the visible area. These |
| 570 | 586 | changes ensure that in most cases flipping should Just Work for |
| 571 | 587 | drivers that use MCFG_RAW_PARAMs, games that have a programmable CRTC, |
| 572 | 588 | and games that have raster effects, and should fix many longstanding |
