Galaga wouldn't load via MAME4All nor other cores due to missing files

[supersmilers]

Well, the Mame4all extracts the files to such similar zip via clrmamepro:

and you can see, its missing some files that clearly exist in MAME64 version like 2n.bin is same as prom-4.2n but different extension hence MAME4all won't find it

[herb_fargus]

@supersmilers different versions of mame have different romsets even if the files are the same. its all explained on the wiki page you keep ignoring.

[supersmilers]

@herb_fargus Oh. I guess. Well, I guess I have to find one with common romset as MAME64.
Gotta keep looking with RomCenter
Oh I found it: AdvancedMAME 1.2

[supersmilers]

FYI:
this is what I found:

Looks like I'm on track

[dankcushions]

i don't understand what the problem is. clrmamepro should rename all these files for you, if they are the correct checksum. it's all in the wiki.

[supersmilers]

@dankcushions Oh. look here... I found out that Advmame datfile doesn't have filesize for the samples... So I'm going to manually edit the datfile to get RomCenter to detect it.

[dankcushions]

samples aren't placed in the zip in my experience. certainly not mandatory to get it to run.

[supersmilers]

@dankcushions well it is for donkey kong and others because some rely on effects for timing.

[dankcushions]

no, samples are not mandatory to load donkey kong.

[supersmilers]

@dankcushions oh

[Finhead]

Smaples are only for certain sound effects in mame4all. It'll run fine without it.
Why not just download the correct romset for the correct mame? Shows in the wiki that you have been pointed to what version works with what romset.
Here is the MAME wiki again

You might need Namco ROM 5.1 and or 5.4. Download 'm from the known places. My Pi version of Advance Mame needs 'm to play certain Namco games, but the Mame4all version doesn't...

Bear in mind, like others said, that there are quite al lot of Mame versions and each needs it own ROM set to plague us retro-gamers.

Succes. :-)
