Re: Rayman DOS versions - no-CD patches


Wow, what a bizarre situation. That explains why I never encountered it - I kept my original (compressed) EXEs and had the modified files at different names.

I will go back at some point and test all versions with the original names, to see which ones are affected. Hopefully, it won't be hard to ...

Re: Rayman DOS versions - no-CD patches

Well, I think I have solved the mystery. :D :D

It turns out that the European versions must have RAYMAN.EXE check, apparently it is crc check, since changing a single byte fails.

If I put the patched EXE with another name than RAYMAN.EXE and I keep the original RAYMAN.EXE, I can run without ...

Re: Rayman DOS versions - no-CD patches

I realized that my original CD is version 1.20, I downloaded v1.12 from redump thinking it was my version.

In any case, patching only 0x8F10E in v1.12 doesn't work either, actually with or without patch it does the same, ubisoft logo, rayman animation, frozen.

It strikes me that I get to start the ...

Re: Rayman DOS versions - no-CD patches

What about the decompressed, but unpatched version? Does that work fine with the CD in drive, or does it also freeze?

Unfortunately it does not work either, same result.


I include 3 executables.

- Uncompressed with PMWUNLIT, patched and unpatched.
- Uncompressed with pmwunlic unpatched, differs ...

Re: Rayman DOS versions - no-CD patches

Ok, I think it's correct, but it's not too much to check it.

Rayman.exe compressed size: 425.468 bytes (MD5: 9f2fb7fec4e4982de3abf6597bf9ca41)

Rayman.exe decompressed size: 928.110 bytes

ORIGINAL VS. PATCHED
0008E968: 75 EB
0008E997: 75 B0
0008E998: 0F 00
0008EA58: 01 00
0008EA6B: 0F 90

Re: Rayman DOS versions - no-CD patches

Hello

I recently discovered these nocd patches and I tried to replicate with the version "Rayman (EU) v1.12".

The decompression and patching went well, but once I run the game, after the ubisoft logo and rayman animation, it freezes and does not reach the menu.
With the original executable, it ...
