lr-beetle-supergrafx is now very laggy.

lr-beetle-supergrafx is slow and laggy for me as well for SuperGrafx games since the new update.

Roms load fine, just run and sound like crap. Especially SuperGrafx; pretty much unplayable. For PCE/PCECD games, they are playable but the music is choppy af

Edit: If we could get an administrator to look at this it would be appreciated.

An administrator here on the retropie forum can't do much..that has nothing to do with RetroPie or Emulation Station..it has everything to do with Retroarch..specifically the core itself. So you will get faster results posting a problem report here (and they need to know so they can fix it):

https://github.com/libretro/beetle-supergrafx-libretro

And it looks like this is not the only problem.

I updated my supergrax core to test and it appears you are correct. The "old" core does not have this problem you describe as far as I can tell.

So it does appear to be a coding issue. I'm sure they will get it fixed. Keep a hold of your old ones everybody..at least for now.

@akafox Can you give me the name of a game to test on it (that illustrates the issue) - I will roll back the code to see where the issue started and do a bug report.

@buzz dai makai mura (supergrafx ghouls and ghosts) is super obvious

RedBatman

Ninja spirit is another one.

I have debugged and found the issue. When CHD support was added, a DEBUG flag was left switched on which affects performance. I have submitted a fix upstream here - https://github.com/libretro/beetle-supergrafx-libretro/pull/29

(RetroArch really need to do more reviews of PRs)

RedBatman

@buzz Thanks

RedBatman

Uh do I have to update from source? Cause I did a binary update an no dice on fixing it.

BuZz

@redbatman the fix is not yet accepted. I opened a Pull Request. Upstream needs to merge it. When they do you can install from source (or wait for me to update binaries).

RedBatman

@buzz Okay thanks again.

Holy...really!!!!?? wags my tail excitedly can not wait to try this out! Finally I can fit some bin/cues on a sd card! :D

Hey BuZz What version of CHDs is used?
(I forget the numbers..but I'll get them posted if anybody cares.)

BuZz

@akafox no idea. Not checked.

akafox

@buzz So I just compiled it. I used no flags and turned off the debug in the makefile. Compiled no errors. I don't know if I need enable some flags or not. Or at least tell it to compile for the rasp pi.

Seems to have worked though. The core loads and plays smooth. Have not tried the chd yet..i'll get back to you on that.

Other thing the core that I compiled through retropie is 1.9MB the on I compiled is only 810.3 kb.....huh?? lol

akafox

Ok so the chd info I used Exile II: Wicked Phenomenon in cue/bin form..together they run 535.2MB. The chd is 285.0MB. I kept getting an error on the starting the game though. "This software is super CD-ROM and requires either the turboduo or the super system card 3.0" Not sure there..get that on both cores...
(Anyone have a solution?)

So..I'll test another...
Bishoujo Senshi Sailor Moon cue/iso format 548.2MB chdman reports a 48% crushd down to 237.8MB. Not too shabby. It loads just fine. No problems sound and all. Runs smooth.

Note that I had to manually add the .chd extension to the es_systems.cfg by typing sudo nano /etc/emulationstation/es_systems.cfg Then I looked for pcengine (ctrl+w) and then between <extension> tags I inserted .chd and .CHD and saved the file. Finally restarted emulationstation. ES found it and loaded it just like any other game.

The pce fast core will load cd-com only in cue the supergrafx will load cue or chd. Maybe they will add that to the fast core soon. Anyway those are my findings.

@akafox I tried Exile 2 chd on pce-fast. It works fine. Now to convert the rest of my library. I used QT Chdman gui with default compression. Can't troubleshoot the problem because it's my first time converting to chd and it worked on the first try.

edmaul69

@darksavior what are you using to convert them?

Darksavior

@edmaul69 QT Chdman gui which is a part of the qmc2 package http://qmc2.batcom-it.net/index.php/download

You still need to hunt down chdman.exe seperately. I could only find it in that killer instinct backup guide website. Unless anyone recommends a later version.
EDIT: Doh, latest is in the mame package. I'll restart my conversions..good thing I have a 6 core(12 thread) cpu:)
Re-tested Exile 2 with mame 0.188's chdman.exe..still works.

darknior

Just for information, yesterday i try the 5 games on SuperGrafx and all is working fine for me. I only use this emulator for SuperGrafx games :)

akafox

@darksavior So strange..I wonder what my problem is then..I know it worked at one point. It says something about the card 3.0 but..I have that..or I wouldn't be able to even start the game in retroarch...shrugs

Are you sure it was the pce fast core? my setup won't even see a chd with that core..even on a pc..but I could be wrong..

And yes i am using QT Chdman gui as well...

On a side note...Crash Team Racing (for the psx) is 605.7 MB cue/bin. pbp format is (and works perfectly..and supported in the psx core) is 372.9 MB. The chd from is 317.9MB (but of course I have no way of testing it..yet..) This is good news though for our PIs..that can only hold 512GB (once they are less than $125.00!) on an sd card. Yeah I know we can use a hard drive but that is just more wires and cords and stuff that can go wrong.. ;)
