Coverage stats are not full

[ocvit]

I've compared current coverage stats with full catalog from Redump and it looks like the total counts are mostly lower than expected.

The number of image files in repo is also out of sync. As well as missing_covers.txt registry.

Serial	Found	Files in repo	Total	Total (Redump)	Missing	Missing (.txt)	Missing (Redump)
SLPS	3012	3092	3146	3483	134	127	471
SLES	2253	2256	2309	2654	56	54	401

Also, there are few serial types that were not mentioned before:

Serial	Total (Redump)
Part	20
DTL	5
SPUS	1
PSX0005	1
PSXCDCLEAN	1
KRT	1
DK	1

These serial types are not present on Redump:

Serial	Found	Files in repo	Total	Total (Redump)
HPS	2	2	2	0
CPCS	2	1	2	0
SCEs	1	0	1	0
SCAJ	1	1	1	0
PL	0	0	1	0

I'm really curious about SCEs as it seems like a non-normalized SCES and it's not even present in missing_covers.txt.

Anyway, is anybody in charge of these stats? And is this repo alive?

Hello, for this repo I used Duckstation gamedb.json file.

[ocvit]

Hi @xlenore,

Duckstation uses an approach of merging multiple editions of game into a single serial. It might work for ISOs with the same CRC, but it's a bad thing for us, because those editions might have completely different covers.

For example, Colin McRae Rally (PAL) [ITA] was released in 4 editions:

• SLES-01204 - Original
• SLES-01204# - Platinum
• SLES-01204#2 - Value Series
• SLES-01204#3 - Bestsellers

Here is Original:

And here is Platinum:

And they're simplified to a single SLES-01204 in gamedb.yaml.

So is this repo Duckstation-specific, i.e. we should have games they support and in a format they prefer only? Or this should be a bigger and more accurate catalog of covers?

Thanks
