Getting the following error message - Xdelta3: target window checksum mismatch: XD3_Invalid_Input #199

Open Flowtac opened 9 years ago

Hello, I am currently attempting to patch the japanese ROM of Clock Tower: The First Fear for PlayStation with an english patch that was released back in May, at this link:

http://www.romhacking.net/translations/2337/

However, whenever I attempt to patch the ROM, I end up with the following error message: Xdelta3: target window checksum mismatch: XD3_Invalid_Input

I have played the ROM and it is indeed the same game that this patch was made for, and I just used XDelta today to patch a couple other ROMs, so I don't get why I'm suddenly having this issue. Can anyone help me out please?

Generally, this suggests that the input source file (i.e, the old version) is not exactly the same as the one the patch was generated for. Could you run a sha1 checksum over the data and compare with the one that was used to generate the patch?

There is an ideal world in which xdelta would detect this situation and plainly tell you what was happening. The problem is that implementing this inside xdelta would make it cost significantly more (e.g., twice as much CPU usage, half as fast). It's best to verify checksums of the input and output files independently, before and after running xdelta.

Did you read readme.txt?

The CD-ROM has two tracks, the second being an audio track which consists of the random bonus song file, LIKE55.WAV. Because of this structure, using different ripping programs will result in images with slightly different data at the junction between the two tracks. The rip that the patch was based on was created with a separate .BIN file for each track.

Looking into delta header, I see that patch was made on file Track1.bin

entao para evitar esse erro que ninguem consegue explicar desative a caixa que diz "Validation Checksum"!! validação de checksum

to avoid the error uncheck the box Validation Checksum
