Coinops is ok when it comes to arcade emulation. But it's console emulation is waaaay behind... The standalone emulators are far improved. For example..
Atarixlbox - Better sound and volume (sound in coinops core is crap). Overlay support for 5200 games. Better mapping for 5200 games. 5200 analog stick support. VAPI (atx) image support. NTSC filter. Artifact mode fixed. Trackball support (5200). Lightgun support. Up to 4 drives with disks loaded and disk rotate option. Joystick port swap for games like wizard of war. Dual stick support (5200 Robotron, Space Dungeon). 6 5200 games that did not work before work now.
AdamX - New and better sound engine. Overlay support. Support for MegaCart games (Pac-man Collection). Support for SGM memory extension. Support for roller controller, speed roller and driving controller. Change disk function works properly (Adam mode).
BlissX (Intellivision) - Overlay support. Support for newer homebrew games. Intellvoice actually works. ECS keyboard mapped so ECS games are playable.
NeoGenesis - GensX and Genesis Plus GX core. Sound improved. Support for redump images and Darkwater Images plus they can be streamed across a network. Better 4-player adapter support.
BlueMSX - Fixes for numerous games (in particular konami games) and other stuff.
MednafenX PCE - Support for redump images.
Pcsxbox - Loads of compatibility improvements. Several games that did not load or play are playable. Fixed CDDA audio. Improved GTE engine. Support for redump images. Network streaming of CD games and other goodies.
Vice64x - Support for more recent versions of gamebase. Jiffydos support. Sound stutter on PAL games fixed. 1571 disk image support. REU image support.
WinstonX - Less ambigious TOS image use and naming. Overscan display properly. Autounzip of HARDDISK.zip images. Screensize modified to more accurately match the ST screen size. NTS/PAL options.
Winuaex -> Tons of Amiga CD32 fixes making CD32 games MUCH more playable. IPF image support. Improved "Clip excess border" code.
X68000x -> XF1 thru XF5, OP1 and OP2 keys mappable to the Xbox controller (some games need this). A couple other things that slip my mind.
A7800x -> Maria code improved fixing numerous games (like xevious, Kung-Fu Master). High score cart support. Rewind works properly. Dual stick support (Robotron). Proper two button support (Dark Chambers, Asteroids).
Z26 -> Better more accurate sound. Fixed games that use the booster grip ( Thrust, Omega Race ) and games with auto joystick detection (Astroblast), not released just yet.
These are just off the top of my head.
