lr-race for Neo Geo Pocket/Neo Geo Pocket Color

mitu

@celly Are the existing emulators (lr-fbneo, lr-beetle-ngp) too slow for a Pi Zero ?

celly

@mitu brutally slow on a zero.

mitu

You can try this scriptmodule to install it and see if it runs better. I don't have a Pi Zero installed right now, I only tested it when it was released - but didn't notice any differences on a Pi3. Probably because the Pi3 is able to run the beetle-ngp core at fullspeed.

lr-fbneo was recently added as an emulator for this system(s), so if you update your Setup script and re-install lr-fbneo, you can give a try to see who it works.

celly

@mitu ok I’ll try that. Thank you. And sorry to ask this dumb question, the .sh just gets plopped into the retropie setup/scriptmodules/libretrocores folder right?

mitu

@celly Yes, you just copy it there, then you'll be able to install lr-race from the experimental packages section.

celly

@mitu well I ftp's the file to the libretrocores folder and it crashes the RetroPie Setup before opening.
Saying that the lr-race.sh is missing valid rp_module_desc. I'll give lr-fbneo a spin right quick after I remove the file.

How did you save the file ? Make sure you download it via https://raw.githubusercontent.com/cmitu/RetroPie-Setup/new-race-ngp/scriptmodules/libretrocores/lr-race.sh. I have a recent RetroPie-Setup installation and I'm able to install it fine.

celly

@mitu same way. Looks like I didn’t get it all first shot. Got it now but, I have to wait for lr-fbneo to finish updating from source to try it.

@celly i don't expect fbneo to run ngp at full speed on pi0

celly

Mitu’s race.sh did not work again, idk whats up there. And after what seemed like forever updating from source, Lr-fbneo doesn’t want to load any roms.
I’m on stretch so it’s not an underlining issue there. It’s cool guy, I appreciate you helping out. I can still play these on my Pi3 no problem.

Did not work how? Did it build lr-race successfully? Or is it quiting when you try launching a ROM?

celly

@quicksilver I ftp the race.sh file over to my GPi Case, in the correct directory. Then restart ES. Then try and open Retro-Pie Setup and it throws up an error and kicks me back to ES. Don’t know why. And the only way to get Setup to start again is to remove the file that I put in there.

celly

Okay I got it working now. I wasn't saving it correctly, thought I needed to copy it all and save it to another blank doc then rename as the .sh. Never mind, all good. And yeah, lr-race plays like sh@t just like lr-beetle-ngp. The pi zero just isn't powerful or the cores aren't updated to work with it. Thanks @Mitu, @barbudreadmon and @quicksilver. I'll just play these on original hardware if I want to take it on the go.

lr-fbneo uses romsets (see https://github.com/libretro/FBNeo/tree/master/src/burner/libretro#emulating-consoles), but again i don't think it would play nice on pi0.

the fact lr-race doesn't play nice or even any better than beetle is weird, lr-race is optimized for psp (which i believe is less powerful than a pi0), maybe its dynarec(s?) were disabled or something ?

barbudreadmon

@mitu i took a look at the core makefiles, there is an optional DRZ80=1which seems to turn on something that looks like an arm dynarec.

mitu

@barbudreadmon Thanks, it looks like this may add some speed-up.
@celly if you want to re-test with the new added option, you can re-download the scriptmodule and re-install (from source).

celly

@mitu i will, thank you @mitu!

celly

@mitu Ok I grabbed the file again and then updated from source. Now after I launch a game, it kicks me back to Emulationstation. I’ll get the log file if you want but at this point, I’m over it. Thank you for all your help, I appreciate it.

mitu

I actually didn't test the new build option in-game. I'll give it a test later on, no need to send the log. Thanks for testing it.

celly

@mitu I couldn’t give up. After some google-fu I found a reddit thread about it with a working script. And man I gotta tell ya, this plays so well.
