WinUAE and sound/music problems

[StealthDwarf]

Hi everybody

I ve recently started to emulate Amiga (in order to rediscover the sensations of my teenage years with my old Amiga 1200 ^^) and I took WinUAE because a lot of people says that’s the best emulator so far.
I had some troubles with configuration (not an expert with that ) but it finally work.

But, I noticed that some games haven’t the same musics I had on my Amiga 1200; like if a part of it is missing (some « instruments »); and even if it s not a real problem to play, like I said in my member presentation, music was one of the things I loved so much with Amiga 1200.

So I m looking for help; maybe someone have an idea from what this problem come from:
- a bad configuration ?
- winUAE Itself?
- a bad kickstart file?
- a problem in the rom of the game?
- a plot of the Antarctica’s beavers?

And if someone have an idea to solve this problem too

Thanks a lot

Heya StealthDwarf,

Can you give examples of games where you say parts (some instruments) are missing?

If you're no expert with configurations then start with Quickstart settings to begin with.

Perhaps it's only the memory which give you this impression

I strongly doubt music could be played in "different" way under emulation

This can happen if CPU is too fast and player routine uses CPU delay loop in "dma wait" routine (This is very common). But it shouldn't happen in emulation if 68020+ because it has special hack to prevent it from happening.

Thanks for your answers all of you

It s very noticeable in Lemmings for exemple on the first track of taxing difficulty:

It suppose to be like that:

And for me it s more like that (but the « scratching » sound is remplacés by blank) - it starts at 3:41:38 :

I just tested "Taxing - Level 18" on this .ADF set (A500 / OCS / KS 1.3 / 512KB Chip & 512KB Slow RAM) and no issue...

... Lemmings (1991)(Psygnosis)(Disk 1 of 2)[cr SKR][t +20 Slipstream].adf
... Lemmings (1991)(Psygnosis)(Disk 2 of 2)[cr SKR].adf

Are you using the floppy version, hard drive installed or WHDLoad?

What configuration do you have set?

My config was A1200/AGA/ks 1.3/1mb both chip and slow ram

I ve tried with the same config as you but with the same issue.

I m using a floppy version (an adf image mounted on the virtual floppy drive) but it s name is different than you adf.

Maybe it s really a rom problem?
Or my ks version

Where did you found your adf?

This is an A500 game so definitely use that configuration with the floppy disk version; like back in the day.

Even for an A1200, your configuration is messed up i.e. KS 1.3 with 1MB Chip and Slow RAM.

A standard A1200 has either a KS 3.0 or 3.1, and 2MB Chip only...

This is why I said previously if you don't know what you are doing use "Quickstarts"

On the EAB File Server, here are direct links:

... Lemmings (1991)(Psygnosis)(Disk 1 of 2)[cr SR][t +20 Slipstream].zip
... Lemmings (1991)(Psygnosis)(Disk 2 of 2)[cr SR].zip

Sorry, this is 3.1 and not 1.3 I have on my set up ^^

I ll make a try with QuickStart and with your links

Ok, I'll list a few things:

A500 ROMs:
... KS ROM v1.2 (A500,A1000,A2000) rev 33.180 (256k).rom
... KS ROM v1.3 (A500,A1000,A2000) rev 34.5 (256k).rom
... KS ROM v3.1 (A500,A600,A2000) rev 40.63 (512k).rom

A1200 ROMs:
... KS ROM v3.0 (A1200) rev 39.106 (512k).rom
... KS ROM v3.1 (A1200) rev 40.68 (512k).rom

Cool

Make sure you scan your ROMs first though i.e. start WinUAE --> Paths --> Rescan ROMs.

If faced with this problem i'd first attempt to play a few mods with some player, under normal WB. Would remove the lemmings from the equation (so we know it's not a rodent problem and therefore not a plot of the Antarctica’s beavers ).

I ce made the test with QuickStart A500 and with your roms but the problem is still here.

Thanks for your links, I ll try all this tomorrow (I don t have time tonight ^^)

Oh I forgot to mention... if using the Quickstart for an A500 then make sure you select "Best compatibility" i.e. slider all the way to the left.

This sets "Cycle-exact (Full)" and should be used for virtually all A500 / A500+ / A600 games.

Maybe you're aware of this but it's something to rule out

The Amiga has 4 hardware "voices" - two in each stereo channel. This means everything is always panned either hard left or hard right.

If there is something wrong with your sound settings in Windows, like left-right balance not set in the middle, or your speaker cables etc etc, it makes sense that you would only hear half the sounds that you are expecting to hear.

I didn’t know that. I ll look in the windows setting but I don’t think it s speakers because that occurs with and without a headphone

Can you post the config you use please?
