Early screenshots of Snow Go (4)

The problem with the infinitely spawning items is still not resolved, but I decided to continue level design nevertheless. Coming up over the next few days I must do university work, so this may be the only update until around Friday at the earliest.

If you manage to do the entire death route backwards,
this little den of safety awaits.



The red gem has a new home... and explosive bodyguards.

No, I have no idea where I'm going with this. This is very
much subject to change.

That third screenshot obviously took the longest to set up and currently requires 3D jumping to score all of the boxes. I doubt it'll make the final build of the level in its current form.

Anyways, hope you all have a great evening, and see you again.

The making of the mod thus far...

Since I'm having absolutely no luck with resolving the issue of infinitely spawning objects, and it's even affecting boxes too now, I have no new section designs to show today. This problem is not one I can solve easily and will probably have to wait for my brother to return from his university so we can both knock our heads together to come up with a solution; that will occur approximately one week from now, so it's not too far away.

In the meantime, I've taken some screenshots of the program that I am currently writing to mod Crash 2, and this program is how I have built all my sections thus far. I recommend clicking on the images so you can actually see what all the text is about.


Crash 2's levels are broken down into 64KB chunks, and these are broken down further in a small file tree structure. Entries within have a type identifier. The one I mod are ones of type 7, which contain the objects among other things.

This interface is what you see upon selecting an object.

Every single object within Crash 2, and the same goes for Crash 3, has a standard, very readable, English name, left behind by the developers. They usually go along the lines of "obj_(type)_(variant)_(number)". You can tell which objects I have named, as they do not follow this convention. Each object can be uniquely identified by its name, however there is no need for the names to be different at all; the PlayStation doesn't use these names to reference objects, they're just for the developers, as far as I'm aware.

Position data speaks for itself; this is where the object sits in the level. X is left-right, Y is up-down, and Z is depth, though interestingly the higher Z is, the closer to the screen the object appears. Values in here are relative to the section in which the object resides. If an object has more than one position, it's usually a wandering enemy, and the positions indicate where it'll walk to.

Object ID is a unique identifier of the object, and is used for rendering purposes and for the game to have a reliable method of tracking whether an object has been collected/destroyed or not.

Object Type dictates what the object is, and if there are lots of types of said object (e.g. a box), variant determines which one.

The General Settings contain numbers for specific tasks; e.g. when it comes to boxes, setting the first number to be 97 makes the box always produce a life. Setting the second number to 4 with left bitshift turned off makes the box give you its fruit/contents automatically upon breaking so you don't have to pick it up. You can also use these to dictate if a box is wireframe or not, and which box solidifies next in the sequence when the ! box is hit, if it is. These settings are also used in enemies to dictate their movement speed, or other various properties.

The "Destroys x objects" list usually applies to the Nitro detonation crate. Any ID listed here will be destroyed when the detonator is hit. Yes, it can destroy almost anything, including things that aren't Nitros, or even boxes. TNTs also have this value set sometimes and it's used if you go off-screen before the TNT blows up to ensure it destroys the objects it is supposed to.

The other settings you see do random things, some of which I don't know yet. The configuration for the "obj_checkpoint_emergency" I have shown above is for a ? box that turns into a Checkpoint if you die too many times. The "5" in the 0x288 box identifies which previous Checkpoint it is linked to (the related Checkpoint will also have a 5 in this field). The 3072 seems to dictate what kind of box it is before it turns into a Checkpoint.

This interface is what you see upon selecting the files that
seem to handle the information that renders objects.

This following section is currently incomplete and contains the infamous draw lists that I like to complain about. Draw List 1 indicates when objects should stop drawing, and Draw List 2 indicates when they should start. If you examine the hex, they indicate at what camera position the object will be going off/coming back onto the screen, so they can be used to make rendering VERY efficient by rendering EXACTLY what needs to be rendered only at any given time. The "positions" field shown is actually the route that the camera follows through the level and is directly related to the draw lists.


If space becomes an issue in the tiny 64KB sections, the program can reorder things to generate more room with the "Move this..." button at the top. Adding totally new objects is done on the button right next to it, and the program does its best to seek out the draw lists and add the object to them, though it is not always totally successful; sometimes the object spawned is not totally off-screen before vanishing and whatnot, and at that point the hex editor needs to come out to fix the issue. I've even had one draw list freeze the game for reasons unknown.

All of Crash 2's NSF files have a checksum on them, and changing any data means the checksum needs recalculating. Chadderz, my younger brother, was the one who cracked the checksum; the program updates it upon saving. The "Rehash a file" button has the same functionality, only you don't have to load the file into the editor if you use that button. It's useful if you've been messing with things in a hex editor and want to quickly get things tested.


And that is how I am doing my work! If it becomes stable, I may release it at some point. Currently it's buggy and a little sluggish, but I'll keep on working on it.

It's nicknamed the "NSF Modifier - Ripoff Edition". Why? ...Because my brother made a program called the "SZS Modifier" for Mario Kart Wii. And this program in some ways looks verrrrry similar to his work :P

Well then, have a great evening everyone.

Do you want wumpa fruit with that?

I thought everything was going a little too well somehow, however a nice curveball has arrived to make life complicated.

Currently I have run into a little problem which causes the cloning of certain objects if you visit an area multiple times. I am unsure of the cause, however I get the sneakiest of suspicions that it's the draw list doing it as usual.




That's a lot of wumpa fruit right there. It also rarely clones penguins.

Ironicly, the objects that get cloned are originals, not the objects that I have added (which you would expect to be more glitchy, but evidently the game thinks otherwise). And as you might have suspected, as more and more objects clone, the game rapidly becomes unplayable.

As such, I need to overcome this problem before I can continue level design. So, may be slow progress for a little while, though I hope I can get this resolved quickly.

Early screenshots of Snow Go (3)

I did find a bit of time for Crash modding after all. Here's the latest screenshots; today's theme seems to be rewards for good platforming :P

A section of goodies if you avoid the Nitro! There's
even a life hidden in the wooden bouncy box.

See, I'm not always cruel, here's a Checkpoint!
Now what is that ? box doing above them Nitros...?

The box that makes these solid is hidden away. A good reward
awaits the finder... but it's a double-edged sword.

And that's it for tonight. See you all again!

Early screenshots of Snow Go (2)

More of my time is spent testing that my designs are even possible than actually designing the levels. And correcting draw lists.

Here are some new screenshots of new completed segments for your enjoyment. Tonight they revolve mainly around penguins, with the exception of the first shot. Again, these are subject to change.

Clever jumping nets you more boxes and lives, and conveniently
dodges all Nitros in the vicinity.

Penguin heads make great trampolines.

This penguin's got itself in a dangerous situation...

These penguins have found boxes and look very
proud of themselves for doing so.

Might not be any update tomorrow as Mario Kart recording must take place. Still, I shall see what I can do. See you all again!

A little preview of what else to expect from good old Level 2 :P
What you see here may be subject to change.

If you're after the red gem, you'll be searching the death route.
You'll also be doing it backwards; you'll still need the secret entrance though.

Oh, but good luck getting back out again should you succeed.

This doesn't look too bad, right?
...Well, how is Crash planning to get past that Nitro on the ledge?

That's all from me for tonight. Tomorrow I shall work more on the Death Route interior!

What is this all about...?

If you've just stumbled upon this place at random, you may not be aware of what you've just come across.

This is the blog for the first ever Crash Bandicoot 2 modding fan project; Crash Bandicoot 2: Master Quest. There are no rewards for guessing where that name comes from.

The aim of this project is to go through the 27 levels of Crash 2 and make them harder, significantly harder. At this stage, alterations to the main game's models are not planned, as I do not know how they work. However, moving objects and adding new objects is possible, and can be used to create brand new puzzles and challenges; and that is the ultimate goal. A very good knowledge of Crash's controls will be required to complete the game.

By the by, this isn't just some random fan ranting about what he wishes he could do.

Initial Snow Go designs in action! (By the way, yes, it is possible
to break all of the boxes minus Nitros without taking damage).

This has been confirmed to work on a real PlayStation console as well.

Keep an eye on this blog and my YouTube for updates. I'll also release demos for testing and feedback purposes along the way.

I hope you all enjoy playing this as much as I enjoy creating it! Please also keep in mind that the process of modding the game is slow. As I get more used to doing it, it should speed up, however I will need time. Have fun, Crash fans!
