Reminds me of the good old DOS days.

Bajillion, 4, same difference. One's just a made-up number while the other's real.
And WTF continued the pattern better than PulseAudio, or I'd've listed all 4 REAL drivers.

Maybe we could just tell those people who complain "Get a Virtual OS emulator to run the Windows build on Linux; Byuu has a lot stress as it is!" Four drivers is enough...how many drivers do these people want!?

The problem is there's not a single "right" way to do Linux audio. And every distro has it's own pet project.

Yeah, guess you're right. I don't even use Linux, so, I can't empathize or know how frustrating that would be...

Hi,

I've uploaded a new beta 4 of Regen which contains somewhat major sound emulation updates. I've added an option to boost PSG volume to whatever the user like since I remeber something else, someone else says something else and recordings sound something else. As such, I've been unable to find a way that fits for everyone.

Apart from that, hopefully all the reported sound problems might have been fixed in this release. So don't forget to test them out.

SSG-EG part of my YM2612 core has undergone a major overhaul. So it should be pretty much very close to the real thing now. If you want to check out yourself, here is a recording from the real thing and here is the test ROM to run in Regen and compare results. All credits for these both go out to Nemesis.

And I almost forgot, you can download the beta from here.

And my thanks goes out to a Russian guy for reporting many sound problems but wants to remain anonymous.

stay safe,

AamirM

Nice! Another job well done!

Ah excellent, will test and upload another package in a bit.

Always love updates!

Castlevania Bloodlines BGM 26 still sounds scratchy.

Thanks a lot for your hard work, AamirM!

I'll be testing it in detail very soon. I played Mortal Kombat 2 a bit, and Regen sounds a bit different from Kega there, though I'm not sure which one is correct because it's been a long while since I played MK2 on a real thing

Gosh, I really wish my Sega Megadrive were still alive so I could test it on a real thing... Anyway, what *is* different is the pitch (and the speed) of the voice, e.g. when Shao Kahn says "Fight!!" or "Outstanding!" or "Finish him!", in Regen it sounds a bit more high-pitched and a bit faster than in Kega, though then again, Regen may be right and Kega may be wrong, I simply can't remember such slight details and I can't remember what it sounded like on the real thing...

Anyway, feel free to disregard or look into it if you think it's worth looking into.

No more things to report for now, the SSG-EG part does sound great btw!

Thanks again, I'll keep you posted on any strange things I encounter.

Hi,

@AgetianMereu:

This is the second time someone has reported this MKII problem so I'll be looking into that.

stay safe,

AamirM

It would be really nice if you added VGM/VGZ playback in Regen so it would be easier to test music on the core...

Or would the fact that VGM is frame-accurate instead of cycle-accurate affect the accuracy too much?

Plus, it would be really awesome.

Sound funniness:

Ristar RD2-2 Theme Break Silence

There's faint crackliness of background fluttering instruments in the left and right channels. I don't know if that's present on real hardware. It caught my attention.

King Of Chaos · Post by **King Of Chaos** » Fri Sep 12, 2008 3:06 am

The Sonic 1 Spring Yard Zone bumper sound pop is back too. Will check Sonic 3K too in a bit.

SmartOne · Post by **SmartOne** » Fri Sep 12, 2008 3:21 am

The Sonic 1 bumper isn't bad like it was before. I think it's normal now. Try Sound Test B4.

Thanks, though keep in mind that it just caught my attention as being different, right now I have no idea which one is correct - actually, Regen may be playing it back correctly (or not), I don't have a SMD anymore so I can't check it out for sure on a real thing

It just sounded different to me, and it caught my attention as being something worth pointing out. However, if someone else pointed it out, it's possible that it's not just me :\

I gotta ask since this topic is huge.

I'm busy recommending this emulator to people, and I'm wondering if Sega CD/32X support will ever be added in the future?

And netplay.

Just curious so I can drive in more talking points.

King Of Chaos · Post by **King Of Chaos** » Fri Sep 12, 2008 7:49 pm

Yeah, I think eventually it'll gain Sega CD and 32X support, since Aamir has mentioned he has made changes that will make it easier to add support for more consoles in the future.

With Autofix Checksum on, Lightening Force (U) [c][!] doesn't run.

I imagine that this could apply to more games. Doesn't the [c] tag indicate that the checksum is already correct? If not, Regen isn't "Autofix[ing]" it very well.

Suggestion: Power Off should change video to the grey screen that Regen shows at initialization. Otherwise the Power Off state is easily confused with Pause.

Power Off does return Regen to its initial state, no?

The sequence of actions Pause > Power Off > Load Rom runs the game with no sound and with Pause checked. Clicking Pause completely haults the game, and clicking again toggles the checkmark to off and the game runs normally with sound.

85cocoa · Post by **85cocoa** » Fri Sep 12, 2008 9:35 pm

The [c] means "faulty checksum routines," i.e. the checksum is incorrect because the game's developers set it that way, as opposed to a bad dump. (The relevant GoodTools documentation can be found here.)

A related feature request: Could we consider maintaining a database of ROMs which require specific Autofix Checksum settings (for inclusion with a future version of Regen)?

SmartOne · Post by **SmartOne** » Sat Sep 13, 2008 12:56 am

Thanks for the info. I always forget that some developers don't do it right. Laziness?

SmartOne · Post by **SmartOne** » Sat Sep 13, 2008 1:07 am

Rocket Knight Adventures doesn't sound crystal clear like it does in Kega. Listen to the Konami screen and the title screen sounds.

Hear all the cracklies. Hairy, even.

Is this "more accurate" than Kega, or just not quite there yet?

Why doesn't the documentation contain exact values by which the true level of PSG can be found? (It sounds fine to me how it is, but for accuracy's sake...)

King Of Chaos · Post by **King Of Chaos** » Sat Sep 13, 2008 2:29 am

I wonder if the things we hear is because of the 48000Mz rate Regen uses for SuperHQ mode over the 44100Mz rate Kega uses.

I presume that Kega does the same thing when SuperHQ is enabled.
