I posted this over at the Peavey forum, but it might not see the light of day.
As mentioned by other members of that forum, the original Vypyr Librarian had problems and was abandoned before being fixed.
The biggest problem is writing all presets to the amp - it doesn't work correctly.
Now, for purely educational purposes, I would like to share with you something very interesting.
If a few bytes in the Librarian v1.00 software were different, writing all presets to the amp would work correctly.
The Librarian is a single executable file called PLib.exe
It could be found on that forum.
PLib.exe v1.00 is 1,873,408 bytes in size.
And the Hashes are
CRC32 = e30dabd5
MD5 = b7606f3fbdd7bf7770edb5a96e570586
SHA-256 = 74bc589e57c8b86b0582421364d7bffe68bb6ff37c0b418aaf4016ee3282ec80
In PLib.exe (v1.00)
If the 6 bytes at address 0000A46F
were actually B7 8D 0C 00 00 00
instead of BE 8D 6B FF FF FF
so that the code looked like this:
Code: Select all
0000A460 FF FF 07 7C CA 8A 55 0C 88 95 6B FF FF FF 0F B7 ÿÿ.|ÊŠU.ˆ•kÿÿÿ.·
0000A470 8D 0C 00 00 00 C1 F9 07 80 E1 7F 8B 85 70 FF FF .....Áù.€á.‹…pÿÿNow isn't that very informative and educational?
