Nice work there, I can only imagine how satisfying it must have been when it finally worked! Most likely the way Ed originally intended this to go indeed with his cryptic puzzles :e_grin:
The user manual does say "Experiment with Songs: they can do surprising things", but that's about the only hint ...

First random bit of Ecco II code analysis.

The Asterite .
Curiously enough, he is actually stored as two halves inside two 32-bit variables at RAM addresses 0xD434⁩⁩ and 0xD438⁩⁩ . Every globe is represented by a single bit in those: e.g., 0x0F is 4, 0xFF is 8, etc., up to 32 in each helix ...

Johnny did a marvelous job reverse engineering some of the Ecco aspects. The problem was that there was never much of it documented and with Dark Sea long gone there isn't really a good reliable source of information for the others to pick up.

Since I am following up on some of the sections of ...

I have been profiling both functions responsible for bonus and penalty points and I have got an interesting update on this.

The function responsible for penalizing you when you lose, has got a slightly unpredictable behaviour due to the way it is written works. To me it almost looks like Molnar ...

I think you will be happy to learn that I have now described Ecco II dynamic difficulty in more detail!
Please see this topic: viewtopic.php?p=129

Tides of Time was quite a unique game in many different ways, one of which was its ability to automatically adjust the difficulty based on how well you were progressing through it which was quite a novel concept at a time. But how exactly does this system work and what does it actually take for the ...

I remember this one well! The reflections and glow effect on that Glyph are absolutely gorgeous, thank you for sharing this with us and breaking the ice in this section! Would be absolutely lovely to see more of your works here

Welcome here as well. Has been a while but I like to hope things are nice and neat here!

This archived topic is here to store the results of the EXXO project : sound files extracted from DoTF.
Please note that since .KAT banks do not store the actual filenames and so far I have not been able to reliably link records inside .GDE to them, all filenames simply have numbers next to them ...

I'm sure you're not alone as to me the 3D stages also used to be very challenging for a long while, especially later on in the game!

Rings that are above water but in the middle of the screen are fairly enough to get, even if you just start spamming jumping out of water, there is still a good ...

Appreciate your interest in this! I hope to produce a short article of sorts to better describe how that works. There weren't many games in 1994 that would have dynamic difficulty like that either!

This one must be one of my most ambitious musical project to date. The basic idea for this I had in my head for several years, but every time I'd sit down with my keyboard to actually try and record it, I would not ...

Welcome here as well, happy to see you join the forums also!

Benjámin has been helping us a lot with sourcing all kinds of obscure and often missed information about Ecco and company that created the franchise, such as the recently published article from 576K magazine about Tides of Time and many ...

An excellent question, thank you!

Tides of Time has a fairly complicated dynamic difficulty system where it will award the player a few points for progressing through levels and switch into Hard mode once enough are accumulated. Similarly, dying on a level subtracts points.

The 3D stages are ...

Going to kick this off by sharing this wild thing I've recently learned about. Dreamcast has never looked this good!

Hello and welcome! So incredibly happy to see more of the old guard here! I wasn't around in time to see the Undercaves but long enough for the rest of the Ecco community, definitely happy to see I'm not the only one to have missed this!

Aha, now that is definitely a way to jog my memory, bring on the spoopyness!
Thank you for that, it did help me remember. Wonderful times!

Thank you! Those FM waveforms most definitely left an impression on me and that is kind of what I was going with when recreating those tracks.

To me, Ecco 1 is most definitely Pink Floyd and synths and distortions work here very well, whereas Tides of Time expands on that and its soundtrack I can ...
