Reicast - Any plans to merge updates from the main branch back in?

@BuZz Overall a massive improvement and the annoying date time bug is fixed! As others have noted the speed hasn't changed much but the big plus is more games work with less glitches. I tried the following on a Pi3B+,

Ferrari Challenge - Works and very playable
Buggyheat - Works and is very playable
Crazy Taxi - works but has substantial sound issue.
Crazy taxi 2 - Works and seems to have less sound issue.
Dead or alive - Works, still slow, playable just
Dynamite Cop - Works, but graphics glitches render unplayable
Ferrari Challenge - Works didn't before.
Gauntlet Legends - Works, improved speed and glitches fixed
Giga Wing 2 - Works - insanely hard
GTA2 - Works
Hydro Thunder - works with sound issues
Marvel vs Capcom Clash of super heros - Works
Marvel vs Capcom - Works
Mortal Kombat Gold - Works
Rez - Works
Rippin Riders snowboarding - Works great
Sega GT - Works
Soul Calibur - Works, Faster, a few very minor graphic glithes. Very playable
Soul Fighter - works minor graphical issues, very playable
Spawn - Works but too slow to play. Also sound issues
Star wars Pod Racer - Works great no issue
Street Fighter 3rd Strike Works no issue
Tony Hawk Pro Skater - Works no issues
Toy Commander - Works no issues
Unreal Tournament - Works but major graphical issues render unplayable.

Overall a huge improvement

@jmbooth2000 something to keep in mind is that some of the games you listed as having audio issues are actually just running slow. When the fps drops the audio starts to stutter. Overclocking can help, specifically core_freq or a more powerful device.

Anyone else getting glitches (groups of red lines) on in game on Rez?

Is it likely that this boost to Dreamcast emulation performance could lead to Lr-Reicast being added to Retropie in the near future?

Also I have noticed that this version of Reicast is more advanced than the one available for Android as a stand alone app. I have been using the Android version to attempt to determine if emulation problems are emulator or hardware based.

It's already added, but it's not available on ARM devices, only for PC based installs.

Is this updated version of Reicast now the same as that used currently for RetroArch on Android? I'm trying to find a matching version. Games run very differently in it, there are no graphical errors in the games I tried but game speed is much slower (maybe 50%) speed.

@George-Spiggott no. This is not the libretro core version.

BTW : Border Down is now playable, it wasn't before due to many graphical glitches !

When I play dreamcast games with this new version, I have strange chars that are displayed "behind" the game area that is used. Here is a picture of what I've got:

@toto2000 I would suggest opening a new topic with the info requested here: https://retropie.org.uk/forum/topic/3/read-this-first

@quicksilver I have a PI 3B+, Retropie 4.4.4, reicast installed from binary and updated today. Game is a CDI US version. It used not to work with the previous Reicast version (I filled the reicast compatibility google spreadsheet some weeks ago about this game having glitches). When I tried it again after the update, the game is now playable, no more graphic glitches.

I did again all the gamepad config using retropie-setup/configure packages... then when I ran the game I had this surprise... each keypress/analog stick movement was displayed as white chars "behind" the game canvas. I was wondering if this happened to other people.

When I run any dreamcast game using this new updated version, I have a blinking cursor on the left of the black area, and when I play games, gamepad inputs add new chars on the black area behind... I was wondering what could be the cause of this effect...

@toto2000 I would copy past the info you provided into a new thread. Its not going to get as much visibility here.
