Re: Remade: The Apprentice for PC

Just watched the entire video... really *really* good work! :) :) We know it here, but perhaps you should add to the YouTube description that everything is based on the original sprites, graphics, sound effects, music and level maps? Still an awesome piece of work, in particular knowing as I do that...

Re: Dimo's Quest password recovery

That's interesting. How do you do that ? Part of an example of a CD-i Link session from the cdilink.txt file (included in the download): cdilink -k Download cdistub and keep it active cdilink -c -b 19200 Continue by changing baudrate cdilink -c -dir /nvr List contents of NVRAM cdilink -c -ucopy /nv...

Re: CD-i System ROMS

OMG, I'm seeing this message +12 years too late :) Nice of you to respond after all those years. The forums could use more traffic anyway :D But to answer your question: No, those tools were written before I could even write software myself :) You wouldn't happen to know by whom?

Re: Decoding CD-i audio files

So it's not the CD image that is at fault. Though.. it may have incorrect header data (ie the TOC) that misdirects IsoBuster. I don't think IsoBuster pays any attention to the TOC when extracting files, if you're opening a bare "bin" file it won't even have one. Many of files with issues had (what ...

Re: Decoding CD-i audio files

.. no cheat mode .. Aww. Dimo is one of the best games out there, but with the randomly generated passwords it's only really playable with a fully working (no dead TimeKeeper) console. Leaving the CD-i on for days is not something I'd advise. I wrote a tool to recover the full password set, see Dim...

Re: Dimo's Quest password recovery

Here are some comment from the sources of dimopass : Motivation and basic algorithm. The Dimo's Quest CD-i title issues level passwords after each completed level. By entering this password, the user can start directly at the next level. The list of passwords is different for each CD-i player, becau...

Dimo's Quest password recovery

It appears that the pressed Dimo's Quest does not have a cheat mode. From the Decoding CD-i audio files thread: .. no cheat mode .. Aww.

Re: Decoding CD-i audio files

Froggy Dimo is in there. They did rework the sprite into a (what I call) red crocodile: http://www.shikotei.com/tmp/cdi/DimosQuest - gfxset1 - RedCroc.gif Do you know if this was actually used in the game? There's a different "red crocodile" monster in the gfxset (7 positions to the right of Dimo)....

Re: Decoding CD-i audio files

... level map images for The Apprentice and Dimo's Quest ... I've had plans to do this for years and years, but just never got around to it... Very nice. Thank you! Thank you! One little detail I noticed: in the Dimo's Quest maps, you still have little frog Dimo: http://www.cdiemu.org/img/frog_dimo...

Re: Decoding CD-i audio files

Those CD-DA files were extracted years 'n years ago (early '00s) and have been extensively listened to (still are). Same here, my mp3 files for The Apprentice are dated September 2001 :) They are still on my phone, I listened to them all just last week (I actually have all the Vision Factory audio ...

Re: Decoding CD-i audio files

Next I will be taking a look at Dimo's Quest... Now that was really easy... Simply extracting all the .blk files, hexdumping them and using a few search patterns in vim quickly found all the sound effects in block 2 of the big.blk file in the RTF subdirectory of Dimo's Quest, using the exact same d...

Re: Decoding CD-i audio files

The sound parameters indicate that only half the filter and range parameters are set. The data samples are all ranging from 0x00 to 0x0F (using hex editor, so there's no mistaking it).. indicating that there really is no data in the other channel. Why? Why store a single channel in a stereo format?...

Re: Decoding CD-i audio files

Okay, I think you've almost got it so giving you actual code should not be considered cheating. Here's C++ source from CD-i Emulator for playing a 4-bit sound unit: /** Plays 4-bit sound unit. * * @param pChannel Audio channel. * @param bParam Sound parameter byte. * @param pbData Sound unit data. *...
