GroovyUME v0.151

GroovyUME v0.151 is released. GroovyUME is a custom U.M.E. build mainly aimed at CRT monitors, as we are convinced CRT technology is a must when it comes to enjoying emulation in its full glory. However you can use GroovyMAME to alliviate some of the annoyances associated to emulation on LCD displays, specially for those models which are capable of refreshing at custom rates.

GroovyUME v0.151 Changelog:
- Automatic modeline generation now can be enabled/disabled (new option -modeline_generation): now GroovyMAME can pick your installed modelines as use them as read-only (-modeline_generation 0), or update them dynamically with its automatic modeline generation engine (-modeline_generation 1). In all cases, modelines are evaluated to check their frequencies against your defined monitor working ranges. This option is meant for users who have customized their modelines by using external software like Arcade_OSD, and want GroovyMAME to pick their modelines and only their modelines.

- User defined modelines (new option -modeline): now you can pass a raw modeline to GroovyMAME and it will use it! This makes full control of video timings possible for advanced users. Just add a line like this in your game or driver .ini file:

The only requirement is to have a modeline already available in the system with the same active width and height. Note that magic resolutions also work here, so it's enough to have a magic resolution with the proper height available. Warning: user defined modelines frequencies are NOT checked. Use it at your own risk. This option is provided to allow full freedom for advanced users. Your monitor settings will be overridden and a custom monitor range will be created on the fly to accommodate your modeline. As suggested by rCadeGaming.

- Cleanstretch feature (improved): now the -cleanstretch option admits these values:
* 0 (in mame.ini) = auto, this value allows GroovyMAME to decide whether to use integer scaling.
* 0 (in specific .ini or command line) = force fractional scaling.
* 1 = force integer scaling in both axis.
* 2 = fractional scaling for x-axis, integer scaling for y-axis. This option is manual only (can't be selected automatically). As suggested by Cools.

- Resolution masks (new): now you can specify resolution wild cards like this: -resolution 640x0 or -resolution 0x480, where '0' is a wild card value. As suggested by Dr.Venom.

- Changeres (improved): now dynamic resolution switching inside games only happens if the resulting modeline actually changes. Scaling options, on the other hand, are dynamically updated. This feature, in combination with resolution masks, makes possible to use "super-resolutions" to achieve seamless resolution switching for systems that change the active width frecuently, like the Megadrive. As suggested by Dr.Venom.

- Frame_delay (improved): reduced input latency thanks to improved -frame_delay option, check this thread for more information: http://forum.arcadecontrols.com/index.php/topic,133194.0.html

- Audio latency now admits fractional values (e.g.: -audio_latency 1.5): this makes it possible to find the optimal system specific glitch-safe audio latency value with finer granularity. As suggested by Dr.Venom.

- Black frame insertion (new option -black_frame_insertion): enables black frame insertion, to eliminate eye-tracking motion blur for both CRT and LCD monitors (more information: http://www.blurbusters.com/). It requires a 120 Hz capable display. You need to define either a 120 Hz monitor preset in mame.ini or use a 120 Hz desktop resolution. Then set "black_frame_insertion 1" in mame.ini, this will allow GroovyMAME to enable black frame insertion when required.

- Multi-monitor support: SwitchRes can only target one single monitor at a time, defined by index #0 of the per-window options (screen/aspect/resolution/view). But now, you can have two or more full screen displays at once: SwitchRes will operate on screen #0, and the other screens will be handled by default MAME video functions.

- LCD marquee support: as a consequence of multi-monitor support, now you can use GroovyMAME with an LCD secondary monitor for marquees. You have to set "use_marquees 1" in mame.ini, use a layout that contains marquee artwork, and these options:

- Video timings now saved in .cfg: now GroovyMAME saves the modeline used in the game's specific .cfg file. This feature, combined with GroovyMAME now accepting modelines from .ini files, will allow future third party applications to interface with GroovyMAME's video timing configuration.

- New monitor presets:
* pc_31_120: a preset for 120Hz capable PC CRT monitors, at 31kHz (VGA). Designed for hardware scanlines by frequency doubling. Black frame insertion recommended.
* pc_70_120: same as pc_31_120, but for monitors capable of up to 70kH (SXGA).
* r666b: Rodotron 666B-29 (by rock145).
