  . jpmsru.cpp: Made the existing SRU layouts larger
- Burger Kids: Added PCB layout
- Burning Rival: sed good GFX ROM dumps for clone Burning Rival (Japan). Note: The gfx1 region ROMs were wrongly named (same MPR codes as Arabian Fight) and were otherwise slightly corrupt versions of the Burning Rival ROMs. The sprites had slight corruptions too, despite having the same MPR numbers as the parent (so just bad dumps of the parent ROMs.

- Super Bubble Pop: Enable joystick inputs. Promoted game to working. Looks like it still has (presumed) protection checks remaining. TODO: Level token counter on the right stays stuck after finishing level 1 (internal token counter still works, so you can still progress). Any other protection checks later on?

- SDLMAME: Fixed sound level default for underrunning case (sound\js_sound.js)
- MAME
  . VIDEO RENDERING SYSTEM
    . Use std::clamp for clamping aspect ratio (emu\render.cpp)
    . Don't request OpenGL context (render\drawsdl.cpp)
    . Avoid divide-by-zero with low-resolution time source. Emscripten builds are affected as clock resolution is intentionally degraded to mitigate side channel exfiltration attacks (render\draw13.cpp).
    . Size point primitives properly. This fixes -beam_dot_size being effectively ignored by this renderer (render\drawogl.cpp).
  . DEVICE: Removed set_log and append_log. These helpers were unintuitive and inflexible. In particular, set_log on a write handler would only log when the value is non-zero, which doesn't appear to be the desired behaviour for several uses (emu\devcb.h).
  . PLUGINS: Enable layout plugin by default (plugins\layout\plugin.json). Don't add library plugins to plugin.ini (mame\pluginopts.cpp). Don't write plugin.ini file if no plugins were found (mame\clifront.cpp). Fixes fresh plugin.ini via 'mame -cc' may create empty file (ID 08738).
  . UI
    . Always leave a space between option and description in usage messages (util\options.cpp). Get decimal separator from C++ locale. Also random cleanup (ui\info.cpp).
    . Added a source file filter for system selection menu (ui\utils.cpp). Show system source file in general info (ui\selmenu.cpp). Get decimal separator from C++ locale (ui\devopt.cpp).
    . Replaced imprecise "driver" with "source file" (ui\info.cpp and ui\simpleselgame.cpp)
    . Swap notworking/mechanical warnings, only add initial \n if there were warnings before it. Added \n before 'BTANB' warning strings (ui\info.cpp). 
  . Catch exceptions by const reference (emu\machine.cpp and emu\render.cpp)
  . Consolidated source file path formatting in one place (mame\infoxml.cpp)
  . Consolidated drivers in single files (exterm.cpp, gottlieb.cpp, lkage.cpp and m79amb.cpp)
  . Removed unneeded comment on clickable artwork.
- Compiling
  . Removed some use of set_log (24cdjuke.cpp, champbas.cpp, darius.cpp, imolagp.cpp, kopunch.cpp, ninjaw.cpp, pkspirit.cpp, schick.cpp, slapfght.cpp, slapfght_ms.cpp, spdheat.cpp, sweetland.cpp and vsmjtria.cpp)
  . Flipped include order in bus\nscsi\cd.cpp to put module header immediately after prefix header (nscsi\cd.cpp)
  . Removed some output().set_value() calls (cischeat.cpp, cops.cpp, exidy.cpp, djmain.cpp, ggconnie.cpp, grchamp.cpp, joystand.cpp, jpmimpct.cpp, mcr.cpp, meritm.cpp, midvunit.cpp, mpu4.cpp, mpu5.cpp, namcos11.cpp, namcos12.cpp, othunder.cpp, portrait.cpp, seattle.cpp, segaorun.cpp, sspeedr.cpp, twinkle.cpp and undrfire.cpp). More use of BIT helper (namcos11.cpp, portrait.cpp, grchamp.cpp and othunder.cpp).
  . Replaced pi constant with M_PI (mcs48\mcs48.h and sound\vgm_visualizer.cpp)
  . Fixed some Coverity warnings in the nscsi_apple_cdrom_device (nscsi\cd.cpp)
