No way for playback your inp if nvram was used.

what does this means?

For future:
1. delete NVRAM folder
2. create 'nvram' file (with no extension)
If you will do it NVRAM will be no more problem.

The same for MEMCARD.

1. When shall i do that? Each time I start record?
2. Never had extension

Why so far I had no problem?
Why yesterday I was able to watch it normally and now I cant?

Can I get back my score or lost for ever?

1. One time only. Do it now.
2. Maybe you have hidden extensions knows file types in your Windows setup?

Your replay is lost.

Its setted it in folder types as not to see the extensions

But the point is why so far I had no problem and I suddenly have? Why yesterday night I could watch this playback properly and now I cant? What changed during the night?(pc was off!)

During night nvram content was changed.

Set windows to see extensions.

Why should I see extensions? Is it important?

Is it possible something changed while pc was off?

Next time I ll upload my inps at once

Are you sure that your nvram file will be without extension?

Extersion or no extersion what is the difference?
Why is extrersion so important? The point is that I suddenly wasnt able watch a playback after just a pc restart.

You must swindle MAME that folder NVRAM exist. File name must be IDENTICAL how this folder.

PS. Do you see difference between .doc and .jpg extension?

we r talking about nvram's extension only...

if using a modern wolfmame, think the last GUI of 106 had it....don't use nvram function.

plus, I thought wolfmame automatically does not use nvram when recording(again maybe depends on version used)

..but would use it on playback...so you have to make sure you remove it on playback.

for CLI, there are batch files to rename these before launching each time so no problems.

..but no CLI for you I guess.

So... I must remove it before playback and I must also removing before recording?
So far there was no problem, I wasnt removing anything.

your "so far no problem" was only temporary, that's why nvram files are so bad at first they lure you into believing if i don't remove them they will work, but mame is not in the same state when played back for someone else so just because they work for you with your nvram means someone else might not be able to play it back.

wolfmame provides batch (.bat) srcripts for automatically removing the nasty files before recording and playback. If you use the gui you must remove these files manually (or make nvram file with no extension which may not be compatible with all mames)

also note this varies from rom set to rom set....again why to just make it the same rule for all by not allowing nvram use.
