Post subject:  Snatch Sega Saturn Patch Problems.

Hello everyone, This is my first time posting on the forum, So i am having a problem patching the Sega Saturn version of Policenauts. What was going is that i cannot get the Session 1 on Isobuster for the Policenauts cue, And i am also confused reading the read me file on what should be patched.

So when i do try to patch it with the cue files, I pick the patch, original file but i don't know what to put for the output file. And then i pick the patch, Policenaunt English cue file, And the Nds file for Policenaut it gives me a error message saying "File too short".

Hmm. Would the Emulation Guide thread help at all?
I haven't emulated the Saturn version yet myself so I'm not too familiar with it.

Ah...
Hm. I know I hate to keep putting Artemio on the spot for these (I haven't played Saturn's version yet), but I think maybe he could have a solution perhaps...?

My apologies... :cry:

It would help to know the step you are at:

Quote:
Step 1: Get a copy of Policenauts. The easiest thing to do is buy a hard copy from a reseller.

Step 2: Rip your hard copy of Policenauts to the BIN format. For the Saturn, you can use any ripping program: Alcohol 120%, ImgBurn, CloneCD... Just make sure you use the BIN/CUE format, and, of course, remember that you have to rip all three discs.

Step 3: Install the free version of IsoBuster.

https://www.isobuster.com/download.php

Step 4: Extract the tracks from all of the discs.

This is a bit trickier. Load the first disc's CUE file into IsoBuster. Then you need to right-click on "Session 1" (on the top left part of the screen), "Extract Session 1 (Content)" -> "Extract User Data (*.tao, *.iso, *.img, *.wav)". When the program asks you to choose a destination, use different folders for each disc. Repeat the process with the remaining two discs.

If you want to make sure you have the proper ISO files, here are the corresponding checksums (you can check them with whichever tool you prefer):

CD 1 ISO File:
CRC-32: b3b87f1b
MD5: de3919b70afc9b7c78868e1e856e192d
SHA-1: fdfaf4efe6a451c220cb176bfdb2c09c418e97d2

CD 2 ISO File:
CRC-32: 2f9772a7
MD5: 3f941d382fc288391d38ff8160cb2906
SHA-1: 4f58d526c34718cbc8cbd6952144f1154c0e1458

CD 3 ISO File:
CRC-32: abf12dc9
MD5: 766c9dd21c804ccf3893bca42aa8b6c3
SHA-1: 77ec55c679c3ebb66d2080c00c685c6a53cf8f08

Rename each of the data tracks as POLICENAUTS_(Disc number)-(Track number).ISO (for the first track) and POLICENAUTS_(Disc number)-(Track number).WAV (for the second track). After that, put all of the ISO and WAV files in the same folder.

Step 5: Install xdelta 3.

http://xdelta.org/

Copy the main exe (xdelta3-3.0.11-i686.exe or similar) to the same directory as the ripped ISOs and the patches.

Step 6: Double-click the handy-dandy patch.bat and it will patch the ISOs for you. If you get "XD3_INVALID_INPUT (checksum) error", first make sure the ISO files have the checksums we've mentioned in Step 4. If they match, please post in the relevant thread on the Junker HQ forums (http://forums.junkerhq.net) for help.

(Optional) If you want to do this from DOS, you can go to Start->Run->cmd, navigate to the directory, and enter:

xdelta3-3.0.11-i686.exe -f -d -s POLICENAUTS_1-1.iso NautsSaturnENG-CD1.XDELTA POLICENAUTS_1-1.ENGLISH.iso
xdelta3-3.0.11-i686.exe -f -d -s POLICENAUTS_2-1.iso NautsSaturnENG-CD2.XDELTA POLICENAUTS_2-1.ENGLISH.iso
xdelta3-3.0.11-i686.exe -f -d -s POLICENAUTS_3-1.iso NautsSaturnENG-CD3.XDELTA POLICENAUTS_3-1.ENGLISH.iso

After all of the patches have been applied, make sure the CUE files included in the zip file are with the ISO and WAV files.

Step 7: Play Policenauts
