Working Dreamcast games

@shavecat ok so on original topic, I have working well on standalone reicast:

1. power stone 2
2. gauntlet legends
3. marvel vs Capcom 2
4. crazy taxi 1 and 2
5. dead or alive 2
6. Virtua fighter 3tb
7. soul caliber
8. cannon spike (speed is great but there is a glitching background that renders it unplayable because the polygons keep disappearing/going black)
9. Sega GT
10. Daytona 500
11. Hydro Thunder (a bit slower but still fun, some might call it unplayable though)

I am not a video game purist or competition gamer so my definition of working well is “is it fun to play”? This means there may be lag a bit from time to time or the game runs a step slow, or audio cuts off or scratches for a second here or there, but ultimately I can sit down and have fun playing the game. Someone who spent years perfecting their craft in Marvel vs Capcom or Soul Calibur might see them as “unplayable” because the game doesn’t respond exactly how they are used to from the arcade/Dreamcast.

On lr-reicast I fully support putting it back as an option in the retropie setup menu for Rpi 3b+. Some of the games above run the same, some perhaps a step slower but the retroarch implementation then makes available TONs of settings to tweak that as people experiment may “fix” that or they may see it as a a fair trade off anyhow for just being able to play games without setting up the controllers and getting to access save/load states, the other options etc. the only game that on the settings above became not “working well” under my definition is Virtua Tennis. I did notice as stated by someone else that Daytona was a bit slower and perhaps gets into the verge of not “working well.”

Also, updating retroarch from binary fixed the sound issue I was having so that is also a non-issue with lr-reicast. I did get the stupid frame thing in the corner too but I am sure that will be removed again in a future retroarch binary, and I fixed the setting anyhow.

@buzz based on everyone’s testing what do you think about getting lr-reicast added back to the retropie setup menu for rpi?

[BJRetro]

I was also able to confirm that the setting for analog to digital controls worked in the retroarch menu for lr-reicast as expected, so it fixes the issue with games like Virtua Fighter that were originally programmmed only to work with the dpad when someone only has the choice of one joystick to control all games.

@mitu

Is LR-Reicast in the experimental packages? Or can it be added there?

[mitu]

@skj It is available as a scriptmodule, but it's not enabled for the RPI, only for PC installations.

I was able to get lr-reicast working on my pi3 and played Phantasy Star Online v2 for a little while thanks to this thread (thank you!). I toggled all the speed settings suggested by barbudreadmon. There was no audio and I had an issue with it running too fast at times and then slowdown. I understand the slowdown is inevitable but is there anything to be done about it running too fast?

[BJRetro]

@parallax for the audio two of us had that issue and once we updated retroarch it was fixed. I had a game briefly run fast but then it didn’t do it again so don’t know about that

Does it not run in standalone reicast? There was a recent update for the emulator if you haven't tried in a while.

[parallax]

@BJRetro - Thank you. Updating RA helped, I now have audio.
@quicksilver it wasn't running at all but now the standalone is running now. The speed issue also has been corrected but I can't say for sure what fixed it. As of now I prefer using lr-reicast, it's running PSO well enough for my pi3 without any overclock but I'll probably run a few tests for comparison's sake. Aside from having to quit RA anytime I change a setting (minor inconvenience) I'm quite pleased with the performance.

Capcom Vs. SNK 2 and Street fighter 3 third strike work withouth overclocking really well

How does Zero Gunner 2 run on lr-reicast ? On the new standalone reicast ? Graphic glitches (polygons badly shaped) appeared for me when I updated. One of the very few games that ran worse on the last standalone build.

could we get a scriptmodule added for pi3 to the experimental section ? if certain games are running on the pi3 using LR-Reicast at least its better than nothing at all? i guess more users could test and report the compatibility of the games.

@Stuart2773
yeha , i agree if its fixing issue's we can all try different games..

[quicksilver]

Just tested fur fighters, runs pretty good in standalone reicast though there are some menus that flicker (perhaps due to the auto frameskip?). Lr-reicast actually runs the game more accurately without the flicker and the menus are more accurately rendered but it does run slower.

[shavecat]

@quicksilver
Lr-reicast how can i install it too ?

[mitu]

@Stuart2773 I posted how to modify the existing scriptmodule to be installable on a PI3 - https://retropie.org.uk/forum/topic/21031/working-dreamcast-games/43. Look below (https://retropie.org.uk/forum/topic/21031/working-dreamcast-games/48) for the BIOS files needed and where to place them and also for the modifications needed for making it run (https://retropie.org.uk/forum/topic/21031/working-dreamcast-games/57).

@shavecat I'm very keen to have a go at installing this as well. However the instructions given are for a slightly higher knowledge level than I currently posses.

Thanks for the guide @mitu. If you could give any noob level advice for this I would be most appreciative.

I updated reicast yesterday, I noticed Jet Grind Radio renders shadows now, unfortunately they render and flash sometimes and Jet Grind Radio needs all the performance it can get. Is there a way to disable them again, or do I need the old binary? Do I have to edit the build source? Is there any rundown for reicast emu.cfg file? I've searched and couldn't find anything until I just now installed lr-reicast, which has the core options listed I could try to cross reference.

[BJRetro]

@George-Spiggott

This is the best I can do:

1. update the retropie setup script

2. update Retroarch from the the retropie setup menu choosing the “from binary” option

3. once you reboot and are back in emulation station press F4

4. type sudo nano /home/pi/RetroPie-Setup/scriptmodules/libretrocores/lr-reicast.sh

This lets you edit the lr-reicast setup script to allow it to appear on the raspberry pi retropie setup menu under experimental packages. Edit the lines motion pointed you to:

replace the rp_module_flags with
rp_module_flags=""

in the build_lr-reicast function, replace the single make line with
make platform=rpi3
Press Ctrl and X on your keyboard then y to save changes.

5)type sudo reboot to reboot then in EmulationStation go to the retropie setup menu, manage experimental packages, and lr-reicast should now be there. Install from source.

6. type sudo nano /opt/retropie/configs/dreamcast/emulators.cfg

You will see a line that says lr-reicast= and at the very end of the line inside the last quotation mark put < /dev/null

7. put the bios files you need in the Dreamcast bios folder

8. Dreamcast should now work when you start a game.

If the paths are wrong in steps 4 or 6 let me know as I am not in front of my pi so doing it from memory.

@BJRetro
Thanks , now i can also try it too later ;)

[Stuart2773]

@BJRetro @mitu

just tested this install and works great, i had about 10 games that would not load via the standard reicast and this lr-reicast version loads them ( especially the new independent releases.

its definatley worth considering this adding it to the experimental packages

thank you.
