The BEXT instruction is needed for the Unisonic Champion driver which I'm building. The Intellivision doesn't need it since its EBCA0, EBCA1,EBCA2 and EBCA3 pins are grounded. The method used was a suggestion from RB

zsg2.cpp: Attempt to reduce clicks zsg2.cpp: Made the emphasis filter much more simple. I think this matches hardware, as a filter like this could be implemented with very few gates in hardware. Also reset the filter state when the sample position reaches the start address, this fixes raycris song mamedev#9 taito_zm.cpp: Adjust volume balance, hopefully fixing psyvarrv. I would need hardware recording for proper verification though tms57002: forgot MACC pipelining for some instructions

* taito_zm.cpp : Updates Add DSP, Reduce MCFGs, Add device_mixer_interface for sound gain, Add imperfect_features related to DSP, Add notes * taito_zm.cpp : Fix TMS57002 clock * Improve Taito Zoom ZSG-2 sound emulation zsg2.cpp: implement emphasis filter, this is a noise reduction scheme that amplifies higher frequncies to reduce quantization noise. zsg2.cpp: Add sample interpolation and another adjustable lowpass filter. This seems to be roughly what real hardware does... zsg2.cpp: Improve panning registers and identify DSP output gain registers. * zsg2: minor changes [nw] zsg2: Register 0b appears to be status flags [nw] zsg2: Linear ramping probably makes more sense [nw] * zsg2: slight adjustment of emphasis filter [nw] * zsg2: slight adjustment of emphasis filter #2 [nw] * zsg2: more sober ramping algorithm [nw] * tms57002: add instructions 3c/3d, make them behave as NOP as they're undocumented and not understood * tms57002: Add dready callback for superctr (nw) * tms57002: Fixes to make Taito Zoom DSP working tms57002: Add undocumented instruction saom / raom, they set saturation mode for the ALU. tms57002: Implement MACC pipeline. tms57002: Add callbacks for EMPTY and PC0 pins. tms57002: Add a few unimplemented instructions. tms57002: Proper behavior of CMEM UPLOAD mode. tms57002: Fix an issue where program is not properly loaded if PLOAD is set after a program has already been written. * Documentation fix, properly identified registers as ramping control, will implement that soon [nw] * taito_zm: Working DSP emulation Pretty much OST quality now. A pretty decent upgrade from how it was previously, I'd say. * typo [nw] * just adding some quick notes about the WIP [nw] * Fix build [nw] * zsg2: Proper ramping implemenation, add register map, minor cleanups * oops [nw] * taito_zm.cpp / zsg2.cpp - more improvements zsg2.cpp: Attempt to reduce clicks zsg2.cpp: Made the emphasis filter much more simple. I think this matches hardware, as a filter like this could be implemented with very few gates in hardware.

After another two "tehkanwch" boards were found and dumped (where this ROM matched the parent), and a deeper analisys from Roberto Fresca (who thinks that it was a bitrot, since it was a nonsense modification of a sprite), I've changed the ROM #9 (gfx1) to match the parent, as found on the new dumps.

* Feed mouse/pen/touch pointer events through UI input manager with Win32 and SDL. * Started migrating UI code to use new API and reworking mouse/touch interaction. * emu/render.cpp: Support pressing multiple clickable layout items simultaneously. * emu/render.cpp: Allow UI elements to be drawn in any window. * emu/rendlay.cpp, luaengine_render.cpp: Added layout view events for pointer input. * ui/ui.cpp: Allow the UI handler to control pointer display. * ui/analogipt.cpp: Added mouse/touch and more keys for navigating field state list. * ui/menu.cpp: Use vertical swipe to scroll and horizontal swipe to adjust. * ui/menu.cpp: Draw after processing input - greatly improves responsiveness. * ui/menu.cpp: Ignore keyboard/gamepad input during pointer actions. * ui/selmenu.cpp: Made left/right info pane arrows repeat when held. * ui/selmenu.cpp: Use middle click to move keyboard focus. * ui/selmenu.cpp: Let filter list scroll if it's too tall, and use a bit of horizontal padding. * ui/selmenu.cpp: Improved divider sizing. * ui/state.cpp: Don't allow clicks to pass through the confirm deletion prompt to the menu. * ui/simpleselgame.cpp: Fixed error message display and graphics/sound status not showing. * ui/simpleselgame.cpp: Allow tap/click to dismiss error message. * ui/utils.cpp: Show UI for choice filters when there are no choices - it's less confusing. * modules/input/input_sdl.cpp: Made scaling for mouse scroll better match RawInput and DirectInput. * modules/input/input_rawinput.cpp: Added support for horizontal scroll axis. * modules/input/input_win32.cpp: Added support for scroll axes and more buttons to mouse/lightgun. * modules/debugger/debugimgui.cpp: Don't fight over events with the UI manager - it breaks menus. * osd/windows/window.cpp: Translate mouse position to window cooridinates for scroll wheel events. * osd/sdl/window.cpp: Supply last mouse position for scroll wheel events if possible. * scripts/build/complay.py: Made zero input mask an error - it was only being used to block clicks.
