@Stuart2773 can you define pretty good? At/near full speed? No/minimal visual issues?

playable speed & minimal visual issues

great work with the Sinden Lightgun, have you tried:-
Lupin The Third - The Shooting (naomi)
(i could not get the mame .zip version to work in lr-reicast but the .lst version does work.

I only tried the Zip version but I didn't realise that some might work with the LST file instead so I'll see if I can source them and try, thanks for the suggestion.
-
@Stuart2773 because you aren't using the latest version of the romset
@MrLightgun except if you like unexpected issues, there is no reason for using the deprecated lst format

Hello, someone managed to start the lr-reicast core on RetroPie installed on an Ubuntu Server 18.10 64bit machine?
This core after some seconds hangs completely the retroarch (show some graphics then freeze)...
I tried several combination but i have the same issue on Ubuntu (not server), Lubuntu and i tried an Ubuntu 17.10 32bit version too with no luck.
The Reicast core instead works but doesn't have Naomi/Atomiswave support.
The only thing that seems to work for the lr-reicast core is to create the "10-intel.conf" file and set the AccelMethod option to "uxa" but the graphics become inaccurate and everything runs slower and stuttering.
Someone using Ubuntu could help?

@fastpop72 Please open a new topic, add more details about your system - https://retropie.org.uk/forum/topic/3/read-this-first - and post your RetroArch log file (
/dev/shm/runcommand.log). -

try setting "DRI" to "2" instead

With this method the core doesn't freeze but the whole emulation is more stuttering and texture are inaccurate.

When using lr-reicast on my rpi, I get occasional "hangs". The emulator will freeze up for a few seconds but then resume normally. Standalone reicast doesnt do this. Has anyone else experienced this?

Sorry, idk how to help then, i encountered a similar issue myself after upgrading mesa but setting DRI to 2 seemed to solve my issue without causing side effects to my knowledge. Open sources intel gpu drivers are way too crappy, buy a cheap nvidia gpu and use proprietary drivers if you have room for a video card.

Has anyone had any success getting the two Tomb Raider games for the Dreamcast working?
-
The Reicast Facebook page is posting updates with pics from Tomb Raider, Worms and others. AFAIK this is for the standalone Reicast android app. Should I be excited for more enhancements of the RetroPie Reicast(s) coming or is this a quite separate thing?
-
@George-Spiggott Currently running at 2fps (and i'm talking about a normal computer btw), there is still a long way to go because all 4 dynarecs need a major rewrite, it will take months, maybe years, but yeah winCE support is coming to reicast
-
Ok the WinCE thing is new to me. I assume all of these WinCE games are difficult to emulate https://segaretro.org/Windows_CE
Looks like I'll be sticking with PS1 Tomb Raiders 4 and 5 for a while.

More like a different thing, emulating arcade naomi2 or cave-1k would probably ask for less changes in reicast than emulating wince. A major concern for me is that it will cause the current dynarecs to be more complex, which might end up having an impact on speed for all games.
-
Oh so this WinCE stuff is why Virtua Cop 2 doesn't work, hopefully it keeps on progressing.

@barbudreadmon I just want to make sure I am right on this and am not missing something. With some number of games I feel that they “perform” really well on Dreamcast but there are significant polygon issues. Cannon Spike for instance the characters move around really fluidly but it becomes unplayable because polygons across the whole screen are flashing in and out. I just tried Zombie Revenge on Dreamcast and although not as bad at all as Cannon Spike there is definitely a polygon drop in/drop out fluctuation issue too though it only gets bad in the second scene not the first one. Absent this, sound, character movement etc are excellent. I was watching a video online of
someone playing Expendable on reicast (very old video though, like 2015) and it seems the same issue is happening - game moving fast but polygon issues. I don’t even think that was a Raspberry Pi. Is there any fix I am missing for this on lr-reicast or regular reicast that works on raspberry pi? . -

The only way to solve part of those issues is to use the per-pixel alpha sorting (aka OIT), it won't happen on a raspberry, you need a desktop gpu for this, and a good one.

@barbudreadmon ok got it I thought I remembered something like that but wanted to be sure.
