Hello everyone, and Happy New Year!
Thanks to the help here in the forum I have properly configured my RPI with Advance Menu that invokes PiFBA and MAME4All Pi Pudding .
About PiFBA however I still have some doubts about configuration (maybe it will also help me to better understand MAME4All and generic emulation on rPi)
1. Initially I disabled scanlines option, because on my PC monitor connected via DVI the final effect was "wrong" (scanlines too thin and non-uniform) but recently I connected my RPI via HDMI to my plasma HD TV and, enabling the filter, the effect seems correct and very similar to a CRT (and absolutely cool and stunning)!
I think that the effectiveness of scanlines option depends on the resolution, so: how does it work exactly? at which resolution PiFBA runs the various games (I mean the emulator, not the various front-ends)? It is possible to "fix" a resolution (via config emulator or boot RPI) to make sure that scanlines effect is always correct, and if yes, what is a recommended resolution for every HD TV?
2. I don't know whether it is a compromise due to the high performance of the emulator on the rPi, but in all games with scrolling elements (without any filter enabled) I see a kind of "lines" or "cuts", like an invisible "grid" or tesselation applied to games graphics. It is "normal"?
3. In the thread I read about a problem with colors on Metal Slug 2 with an old version of the emulator... I don't know if problem has been solved with a new release (I see Metal Slug 2 correctly) but I have a similar problem with Power Instinct games.
Precisely in Power Instinct 1 where there should be white, there is a salmon pink (same romset works perfectly in MAME4All Pi, albeit with lower performance) while Power Instinct 2 and Legends have some problems with music: is too slow in the U.S. version of the games, and too fast in the JAP version.
I don't know if this is a problem of the emulator itself or of the adaptation on rPi, but I wonder if it is somehow fixable: all three titles, apart from these two anomalies, work really well and it would be nice to have them fully functional on Raspberry.
Thank you very much.
