some games from cpc-clean-db 1.2 (from archive.org) are not working, but tosec versions from tosec package is ok

[aderumier]

Hi,

I have problem running some games from the cpc clean db 1.2 package
from:
https://archive.org/details/amstrad-cpc-clean-db

some games example:

sram2
qin
zombi (spain)
zombi (france)
zombi (de)

I have verified, the md5 of dsk are ok and match the .dat

but when I'm lauching them (libretrocap 4.5.4), I have a computer_hash_file error displayed and game is not launching.
Tested with caprice32, the game is not launching too.

If I used .dsk from tosec, the files have different size, and are working correcting (and no crc hash error in libretro)

Verified CRC is that your rom is a clean certified version. Some ORIGINAL games from ERE have protections that cap32 cannot reproduce at this momment. All the games you mention are in fail-db (you see a notification when load this rom if you have that enabled).

Check our list:

The reason that exists clean-cpc is because tosec and other "rom packs" are plenty of cracked/bugged versions.

[aderumier]

thanks for your response !

Sorry, I was confused by clean-cpc-db_have.txt && clean-cpc-db_miss.txt, I thinked that miss.txt was the non working games, and that the hash error was non matching hash.

Just curious, what is your tosec source with originals version ?

[DSkywalk]

No problem, and thanks for your report anyway 👍

The sources are authors pages, my dumps and cleanups and Bruno (Kukulcan) from https://www.cpc-power.com/

clean-cpc db is same idea that no-intro but for our CPC machines 🍰

As you can see in the issue, we started using tosec list as an started source and is was a totally mess... 🗑️
wrong versions, missing loaders, games, loading screens...

[aderumier]

@DSkywalk ah ok, I thinked you was only used tosec as source.

I have looked at another source of original disks, in the "amstradmaniav7" game compilation from 2014:

https://pixeldrain.com/u/HRKCge66

They are a "extras/original disk" directory in the collection:

I tested some of them and they are all working:

sram
sram2
qin
bob morane - science fiction
skate ball

[DSkywalk]

hello @aderumier!
What is the source of this original dump? because for example SRAM original disks are protected by
Protection Remi HERBULOT - 10-1985 - v2.1 (not working on cap32 yet)

more info: https://www.cpc-power.com/index.php?page=protection&lenom=Protection%20Remi%20HERBULOT%20-%2010-1985%20-%20v2.1

One more thing, could you correct your review in archive? because it can be misleading to other users, thanks! 👍

[aderumier]

mmm, indeed I'm not sure they are the original.

I have tried to do myself convert with samdisk tool, from raw dump, and I got the same result, it's not working.

I see on cpc-power that the image is working with Sugarbox emulator, so maybe it's just no yet working with caprice32.

Thanks for your hard work ! (I'll try to contribute soon with remap)

(and I'll fix the comment on archive.org)
