I've tested all scenarios (including both winning and losing on level 2), death screens, complete screens, etc. Everything works.

Starting from your patch, I traced through to the calling routine and found the place to patch in order to skip the doc-check completely. At offset 618 (hex), overwrite 4e ba 07 f2 with 4e 71 4e 71. Works with both 1.0 (not beta) and 1.1 versions.

Enjoy!

I've been looking at the different Roger Rabbit versions.

From what I can tell, all of the ADFs are the same despite sometimes having differing files (eg. "zac_is_it" just waits for a mouseclick, "dust" is a cracktro, etc.). In terms of the game, they seem to be the same after doing file compares and are the beta that Diestro talked about. These files are generally dated November 1988.

Then there's the IPF which does indeed seem to be a more polished game. These files are generally dated February 1989.

But a single pixel bothers me:



Why does the IPF suddenly have a bad pixel in file GR/B2? Did the developer accidentally put that in, or is the IPF actually the older version with this "bug"?

There's also different files in the INS and VOICE directories. In the ADFs, we seem to have way more music and voice files than the IPF. Perhaps the IPF executable simplifies the game's audio code and has everything in a single file?

The plot thickens for a game that 2 people have spent time playing since its release.

no time to polish it and end trainer options. This game is nuts

new version as beta. Needs reinstalling (which isn't an issue since previous version used disk images, just use those disk images as virtual floppies)

I'll give it a test sometime this weekend with WinUAE. Someone else would have to check on a real Amiga.

I too have no time to add the trainer. I've got notes for both versions of the game (memory addresses and so on) so probably just need implementing. One day we'll get around to it.

Thanks for the update, jotd!

[jotd]

yw. The real reason why I'm not finishing the trainer is that ... I don't even know how to get past stage 2. I used a cheat on stage 1 to skip to stage 2 so I could crack the protection. The movie was ok, the game graphics & sound is fine but seriously the playability sucks IMHO

I'd like to do the same for stage 2, and above just to add trainers & test the game fully, on 2 versions (plus the beta?) I don't even know which version I'm supporting besides IPF.

[Radertified]

Just like to say that I haven't forgotten about this.

I've tested the slave with the IPF and that works 100%. Every combination tested.

I've tested the slave with the [cr WOW] ADF and the ending doesn't work. Of course I forgot the ADF itself doesn't work so I wasted time playing it.

I'll test with at least one more ADF (one that I know works!) and if that works, I think it'll be releasable.

I'm also working on finalizing trainer details for the RogerRabbit file in both versions so if I don't have them done after the playthrough, I hope to have them ready a short time after. I want to get this off my plate

And in case anyone's curious, other than the graphical differences between the versions (text colors, loading screens, etc), I've noticed that gameplay is identical between both versions except for the final level where in the ADF (beta?) the weasels are much harder to kill than in the IPF.

[jotd]

difference between 2 versions I'm supporting is basically ... everything. One is coded in C and the other one in assembly.

Code is completely different to do the same thing. Looks like they are 2 completely different games.

Hmmm, I'm using this set in my collection:

... Who Framed Roger Rabbit v1.0 (1988)(Buena Vista)(pre-release)(Disk 1 of 2)[cr WOW].adf
... Who Framed Roger Rabbit v1.0 (1988)(Buena Vista)(pre-release)(Disk 2 of 2)[cr WOW].adf

So the ending is borked hey?

I know GameBase Amiga uses this disk 2: Who Framed Roger Rabbit v1.1 (1988)(Buena Vista)(Disk 2 of 2)[cp manual code].adf

Can you suggest a 100% disk version please?

[Belgarath]

GB Amiga also uses a disk 1 that was cracked by Jason. I can't remember where he told me about this game, whether it's a thread buried on here, a pm or an email but I'm pretty sure he cracked it because there was no 100% adf until then.

That makes *A LOT* of sense. I found that I couldn't just train one version and search for similar bytes in the other. I have to train each version individually, which is a pain!

Yep. It doesn't load the ending screen. The IPF obviously works and is a later version of the game. I'd suggest that. You just miss out on the loading screens and other very minor tweaks that were available in the earlier versions.

As for a 100% version, the GBAmiga one does work, and I know some of the others in TOSEC work too. I can't remember if the GBAmiga one is based on the earlier versions or the IPF.

I've been contemplating doing a 100% version with trainer of the IPF but laziness is telling me to just skip it We'll see how it goes.

Ok, I'll switch to the GameBase files.

Now that would be much appreciated

[jotd]

I can create a cracked adf set from IPFs no sweat if you want.

That's ok, I assume this is what Jason did with the Disk 1 used in Gamebase Amiga.

Now a cracked / trained .ADF set, that would be great. Let's see if Radertified gets around to doing this though

I've already created a crack for it. That took all of 2 seconds.

It's the trainer that's the delay. I have all memory addresses ready for the IPF version. I'm just too lazy to make a trainer. I might just make it a left click for normal game and right click for in-game trainer keys. Seems like the easiest way.

Something worth noting for the WHDLoad slave, @jotd, is it's possible to bypass the protection screen entirely. I haven't tried the ADF but on the IPF if you enter the correct manual protection, the next time you play the game in the same session (ie. don't reboot the Amiga) the protection screen no longer comes up.

I just can't find where the flag is set in my quick search. But if we can find that, it makes this game playable on a CD32 because keyboard is only needed:

- For the manual protection
- When you die and you have to press Y to play again, or N to quit.

Yup, that will do

...and I'll create a text screen for you before loading the game so that people know what these keys are.

[jotd]

okay, if you can share the trainer info, or you can update my whdload slave...

A flag to completely bypass the prot is cool but hard to find by memory diff. But worth it (did that on Prince of Persia it completely bypasses the LEVEL where you have to select the proper potion);

[Radertified]

I'm done. FINALLY! Freaking pain to support the different versions.

@jotd: There's a Paranoimia version you need to support because the file size is different.

I've also managed to bypass the protection screen in every release, so the only place this game needs keyboard is when you die in the final version where you have to press Y to play again, or N to quit.

I also have memory address to skip to the last screen on level 4, but you'd still need to get the cartoon hole, etc. Too much effort to patch it all to just work so I skipped it.

-----

The slave

The slave works great with the IPF.
It should work with the Paranoimia release when supported.
The pre-release ADF's work with the slave however every single release I tried doesn't have the end screen when you complete the game. This isn't a problem with the slave. It's an ADF issue so people should avoid the pre-releases even though they have the loading screens and slightly harder end level.

I guess the only slave issue with the pre-releases is once you die, it sits at the Workbench screen. The slave doesn't quit. No big deal. Quitkey still works.

-----

The ADFs

Regarding the pre-release ADFs in general, they all seem to be the same, except for [cr wow][f] which has a different checksum. The slave works fine with it though.

Regarding the Paranoimia release, it seems to be similar to the IPF, except everything's at different offsets.
What's most interesting is the title screen says 1.1! Not even the IPF says 1.1. And this release has a date of 26 June 1988 while the IPF has 8 February 1989.
Most of the other prerelease ones have a date of 30 August 1988.

So confusing!

-----

I'm done with this game for now. Anyone that wants to take the patch and trainer info and adapt into 100% ADF with trainer can do so. I might eventually get around to it but who knows when that'll be?

[Radertified]

Crap. I forgot to include unlimited lives for level 2. I'll get them done tomorrow.
