Greets and Happy New Years, folks!

I've been working with gensgx-1.7.3 - - I was drawn back into fiddling with it since ekeeke added SEGA CD support, which is a HUGE and WONDERFUL development!


I've been encountering the audio glitch/stutter bug that other have reported, though (see google code page for bug discussion)



Has anyone else encountered this? Specifically Lunar 2 and Popful Mail have noticeable audio glitching, especially Lunar 2, even right away on the title screens.

I am using a GameCube with a QOOB chip, Swiss 0.2, a wiiKey SD card adapter, and some various PNY and SANDISK Class 2-4 cards

Transmission rate is the likely culprit for these audio glitches, it seems, based on reading the bug discussions.

I am considering buying a Class 10 or a UHS 1 speed SD card to see if that helps. Before I do that, however . . .



Questions -

- Has anyone with a working Class 10 card and SD adapter tried some SEGA CD games with gensgx 1.7.3 and NOT gotten the audio glitches ? Have you specifically tried Lunar 2, for example ?

- If it IS working without glitches or stutters for you, what Class 10 are you using, and what should I buy that works with Swiss? Amazon has some decent one, but are UHS speed cards supported by Swiss ? ( examples include http://www.amazon.com/SanDisk-Extreme-C ... =pd_cp_e_2 and http://www.amazon.com/gp/product/B003VN ... irect=true )

Thanks for any ideas or pointers!

Cheers!

I wouldn't go beyond a class 6 card, the likely limiting factor is not the SD card itself but rather the limited ability of the GameCube to read from the card.

You should get better results if you burn the games to a iso9660 DVD-R as the read-rate from there would be faster and wouldn't block the CPU, giving it more time to process audio and emulate the game itself.

Thanks, emu. Appreciate the response.

I thought the same thing last night, so I tried a couple of DVD-R burns - -

- one, a bootable DVD-R with gensplus as the boot.dol; it booted, but then locked on launch (the "green flash" screen, and then hangs on that green screen. That green screen is the same one you see briefly when launching gensplus from SD card, and then it usually moves to the emulator menu)

- two, a simple ISO9660+Joliet DVD-R with a few of the "trouble" games on it; booted to gensplus on the SD card, navigated the menu, chose "DVD" as the folder to load from, and then attempted to load a game; the DVD "mounting" icon spins, and then the emulator freezes and hard locks on the menu/DVD mounting screen

Both the bootable DVD-R and the simple ISO9660 DVD-R are browsable via Swiss and Gcos. I can get to them and see all the files.

It just seems like gensplus is unable to currently load and boot from DVDs


If I remember correctly, however, this is a larger issue with the upstream libraries that are being used for ALL these emulators?

I think that snes9xgx stopped working with DVDs somewhere shortly after version 4.1.1 due to that upstream issue.


I will have to now go back and test a bunch of previous versions of gensplusgx and see if and where it loses DVD support.


Bummer! I was looking forward to some SEGA CD . . . !

-a2a


EDIT: Just went and tested genplus version 1.4.0 and it locked trying to browse the DVD, as well. SO, maybe my method/media for DVD is faulty? I will try some alternate media and ways of burning. I was using IMGBURN to make an ISO9660 disc . . .


SECOND EDIT: Ah, here's the discussion I was referencing with regards to the library and inability to load DVD since a few years ago on multiple emus - -

http://devkitpro.org/viewtopic.php?f=7&t=3050

Also, I went back EVEN further, and tried genplus 1.3.1 - - and it loaded and browsed DVDs just fine. :( No Sega CD support back on that 2008 version of the emu, of course . . .


I think what we have here is an end-of-life situation for DVD support, unless someone wants to tackle it or they fix the libraries!

It currently affects all of the GC emulators based on those libraries, and you would be a hero to many if you could solve that issue!

Well, more of a hero than you already are, I suppose! :)

Without being able to test on a DVD, it's hard to tell if the audio glitching is due to the emulator, or access rates.

Looking at the larger picture in the "Issues" section on the genplus google.code page, you can see that there has been an ongoing struggle with audio issues and the newly adapted Sega CD emulation - -

http://code.google.com/p/genplus-gx/iss ... ail?id=196


Looks like stuttering MAY be resolved while reading Sega CD games from SD cards in a future release.

Or not.

In my reading it also appears that the issue MIGHT be solvable depending on whether one uses BIN, CUE, ISO and how those files were created.


Complex topic, lots of variables . . .



Anyone else been playing with this current release and want to contribute their observations? :)

I played Popful Mail with a 2GB class 4 SD card so I could hear the audio glitches. It made the game kind of irritating. Sometimes the audio cut out for a split second, sometimes it made a 'errrt' sound. The opening video cut out audio every few seconds and in-game speaking was worse. "I'm a errrt-bounty unter, not a errrt-baby errt-sitter, ub." No good.

I moved the same dol and rom to a 32GB class 10 and everything was fine. No audio glitches in-game. Everyone speaks clear and there is no 'errt' sounds. The audio doesn't cut out when characters are talking, but the opening video clip still had a few problems. Lost sound one or two times for a split second. Nowhere near the problems it had on the class 4 card.

The SD card is a Sandisk Ultra 32GB SDHC I Class 10 30MB/s. Works with Swiss just fine.

I think I'll play Popful Mail some more tonight and I'll try Lunar 2 if I get the chance later.

I havn't noticed any stutters or problems since I went to that card. It even plays Double Dash without problems. That was the only game I played that had much of a stutter. I was on an older version of swiss for awhile and wasn't updating my version regularly, like I do now. I'm sure that helps with my game play and compatibility too.

Well, Lunar 2 still has audio disruptions with the class 10 card. Not as bad as the class 4 card, but it is still there. Popful Mail plays almost perfect. Maybe future releases of Gen Plus will be able to read from dvd properly.

That's great information, siphoned! Thanks for chipping in!

And, very importantly - - thanks for the brand and model of your working Class 10! I will have to pick one up.


Yeah, it'd be amazing if you can fix the DVD support, emu, but it sure seems like a "deep" issue - - it's in every emulator release to-date based on that library! :(

it's not a deep issue, just needs about an hour of my free time, which is non-existent until mid April at least.

I'm running the emulator under Datel SD Media Launcher and using this SD card- http://www.amazon.com/gp/product/B002OM81SU/

Popful Mail has some minor audio issues in the opening scene. I heard nothing bad during the spoken dialog scenes in the game. It's BIN/CUE format.
