Thanks to FRS, Manuel Pazos and Theo Wilderbeek we can improve Valis 2 gameplay quite a lot thanks to their patches. While it would be wonderful to be able to apply both of them, I have notice that each one is based on different SHA-1 checksums; so I think they are based on different disks.

Taking a look at their readme files I can see the following:
FRS patch SHA-1 checksums:

SHA1(VALIS2A.DSK)= f9523acb436548cb28816975f4420d79348e6085
SHA1(VALIS2B.DSK)= ff6c49ba7431459ec46db240470b1bad6fec889b
SHA1(VALIS2D.DSK)= 9da06782e01dba621d131e1c874e886ad559680f

English patch SHA-1 checksums:

9c05a8ea55fe6a3813219d7568da50c2e8f4ef4c *valis2-1.dsk
43c12ee91407255e4f69c3d9195df3e778532d0c *valis2-2.dsk
4d30e9c23ebc14f65c7583ff1103ef343054b353 *valis2-3.dsk
c1cc16c542caaec1cee8bd050d9bfdcd2bb71bb8 *valis2-4.dsk

So I wonder: which SHA-1 is the true original master disk? Which one should we use? If someone has the original disks in working condition it would be nice if he could do an image a post the SHA-1 checksum.

Heh, interesting. The ones I had were:

9c5d477304c6f67cb9e4b2007834049c577ceb91  1
7e31fe339aed0a5704f8024c99375d935820a109  2
b575ca93ac83ead2579bc4338382a93a613c11f5  3
1c401af3b3cbcef9e7f504da34129149f41bb929  4

but the one from the Legacy cd has:

db6ac0068a9691701a1bcb628990caddea913572  valis2.1
e82e8a843a17c1c051d862b278816281076e9e97  valis2.2
92aa30bbbc96ed7a742a07f963c0be04b0c4cf6b  valis2.3
9da06782e01dba621d131e1c874e886ad559680f  valis2.4

The original dumps from former FUNet (I think done by 'atarulum') say:

f9523acb436548cb28816975f4420d79348e6085  VALIS21C.DSK
22f4ef51a68218bd5799d183d35c5b5e884c155f  VALIS21O.DSK
ff6c49ba7431459ec46db240470b1bad6fec889b  VALIS22.DSK
92aa30bbbc96ed7a742a07f963c0be04b0c4cf6b  VALIS23.DSK
9da06782e01dba621d131e1c874e886ad559680f  VALIS24.DSK

Where O vs C is Original vs Cracked, where he removed the copy protection. These seem to match with what FRS used as a base.

Bear in mind that the English SHA-1 checksums are from the patched disks.

Probably, any version will be fine for patching it to English, since most of the disk is modified.
SHA-1 of disk 1 might be different due to saved game data.

FRS and English patches are not compatible. But @Victor has made a new patch that combines both, and also adds more improviments. I expect it to be published soon.

On Twich, AnnK_ is playing the ENglish version and then patched with FRS's patch. She said that things are OK after changing clothes to something different than the pajamas. Are there other issues when the patches are combined?

That's not posible because the adresses in DSK are totally diferent in the patch.... Guillian moved the "internal files" when he created his version.. so it's not posible to patch is directly....

But that's solved.. just wait a few days...

Well, she's streaming right now with that configuration... not sure what is going on then. Check it out here: https://www.twitch.tv/annk_

Hi Manuel,

I checked the streaming and it's no possible to check FRS IPS is working because she is not using Turbo R mode; when you use Turbo R with this patch, the scenes are very fast. But in the streaming the interlude scenes are slow as original game. Do you notice any FRS improved in the streaming?

Regards

She is using the turboR. But for disk D, she moved to the disk without the FRS patch, because it hung up.
