![]() Vertical is also from vsync to vsync, for example last visible line of display can be line 0 (or even larger if special programmed mode) which wasn’t fully emulated previously. Display emulation is now from hsync to hsync (not scanline to scanline) which enables accurate emulation of left (programmed modes or blanking modified) and right border (normally visible, position where horizontal position wraps around) edge cases without extra hacks, both bitplanes and sprites.Chipset edge-cases and chipset version specific undocumented behavior emulation improved, for example Copper waiting for Blitter chipset bug is accurately emulated (which causes visible glitches and was not emulated previously), borderblank glitch if horizontal window is opened early.Blitter internal logic emulation updates, for example blitter register modifications when blitter is active are now accurately emulated, line mode with B channel enabled undocumented behavior emulated and more. ![]() Programmed display mode support greatly improved, for example cycle accurate horizontal blanking (even if it is changed mid-screen), badly documented BEAMCON0 bit combinations accurately emulated, previously unknown undocumented features emulated and more. ![]()
