So I've started working a Mario version of GYROMITE, using THE JABU's one player hacked Gyromite. Most of the tiles have been changed but I still have to work out some graphic bugs. I'm trying to make small changes to the levels using the HEX EDITOR, but it's a pain. Is there any Gyromite level editors out there?

** UPDATED 08/26/2015 **

- Graphic overhaul almost complete
- Mario Dolls replaced with Exclamation boxes
- Turn-ip replaced with coin
- Background no longer just black
- Level editor completed




** UPDATED 08/17/2015**

- Phase 01 revamped
- Phase 02 revamped
- Player 2 palettes match player 1, except Koopa which is Blue
- Gyromite playable with only 1 controller, thanks to JABU's hack
- Hack no longer a mario edition, name is officially SUPER KOOPAMITE SPECIAL EDITION
- Thanks to Quick Curly I was able to build a software to edit levels
- Main character changed from Mario to a Koopa
- Enemies no longer Shyguys, changed to Spinnies
- Added climbing animation to Spinnies and Koopa

Are you really planning on mixing the outline-having artstyle smb2 US with the non-outline having SMB1 style?

[JUg]

I haven't decided on the final style yet actually. I might actually use the SMB2 USA sprites for mario as well, since there is a sprite for mario carrying vegetables and stuff. So I guess I have my answer now, I'm planning to go with the outline style of SMB2 USA.

This seems like a very cool idea for a project. Nice work so far.
General rule of thumb: If you Google it and don't find anything other than posts asking if there is a level editor for a specific game, chances are that, unfortunately, there likely isn't one. Similarly, if a game is hacked barely or not at all, chances are that someone likely hasn't taken their time to program a level editor for it. A game really only ever seems to be hacked once there is a utility to simplify the modifying process, which can only come about when someone takes the time to figure out how the game works to begin with, and then has the ability to program a utility to modify the data, normally visually to help the process.

I don't know how much information you have already found yourself, so maybe this post won't be that helpful for you.

Using the FCEUXD emulator, I found the following information for the "Gyromite (W) [!].nes" ROM.

With this information at hand, it might help to draw out the levels that you want to design, and then add them in by hand through a hex editor. At least, until someone looks into this game and designs a level editor for it. However, I don't see this happening anytime soon, unless this thread peeks their interest and motivation enough to do so.
Best of luck with your project!

A level's object data is stored at $0300 in RAM.
Let's look at Phase 01.
Each row is 0x18 (in hex) bytes long. 24 (in decimal) blocks to draw.
There are 12 rows. 24 x 12 = 288 blocks.

Phase 01's object data in RAM is $0300-$041F (0x120).

01 01 00 00 07 00 00 0A 00 00 00 00 0A 00 00 00 07 00 00 00 00 0A 01 01

Phase 01's object data in the ROM is from 0x4B21-0x4BB0 (0x90).

11 00 70 0A 00 00 A0 00 D0 00 0A 11

55 55 55 55 55 55 55 55 55 55 55 55

288 blocks, 144 bytes in decimal representing object data.
So, each byte actually represents two blocks in the object data!

The first 11 represents the first two "01" horizontal construction blocks.
Next, 00 represents two empty tiles.
70 represents the top of a blue gate and then an empty tile.
Etc.

i personally would rather have bombs than mushrooms with fuses on their tops.

[SunGodPortal]

i personally would rather have bombs than mushrooms with fuses on their tops.

I agree. Plus, there were bombs in Mario games so... Only reason I could see for this is if Gyromite likes to eat bombs. I wouldn't know though. I remember trying to play this game a while back and had no idea what to do.

[JUg]

Wow! Ok, well, I had some of the info for Hex editor, but you completed everything I was looking for.

As for the shrooms, yeah, my intention was to remove the fuses later on.

Here is a screenshot of my level editing. Thanks to Quick Curly, this made the process a lot easier. I made an editor in Fusion 2.5 and I exported the level code and pasted in the Hex Editor at the appropriate address. Now I just need to figure out how to move the bombs, the food and the mobs.

You're very welcome.
Wow! That's very impressive! Awesome work!

I realized after I made the post earlier that I had forgotten about the other data. Sorry about that. I looked back in FCEUXD and found it for Phase 01, with the basic direction of how you can find it for all of the other Phases, too.

There is still Game B to consider, too. If you want to know how I found this, use the Code/Data Logger in FCEUX or FCEUXD, load the level, and then look for the bytes lit up in blue. Then, with some trial and error, you can figure things out.
For all of the work that you've evidently already put into this, I hope that you'll be able to see your project through to completion. Best of luck!

Now I can place/remove Smicks, place/remove Dynamites and move the starting position of the professor (if needed). I can also assign new graphics (like the rope) to those part of the layout. I also realized how limited my knowledge was when you started helping me with this. What do you think I should place instead of the turnip? I was thinking of a coin, but I can't make it animated and I would need to swap it's pallette because it shares the same one as the Smicks (for the top part). 6502 is not part of my skill set. I've chosen spinies to replace the shy guys as well. Seemed appropriate.

[M-Tee]

How are you handling the enemy climbing the vine animation?

[Grimlock]

How are you handling the enemy climbing the vine animation?

Rotating the sprite (raising the head end up) somewhere between 22~45-deg might be worth trying.  It still might look funky but it would be better than duplicating the walking animation (like it's floating up.

Another idea you could try is rotate the sprite 90-deg, face up and just have the sprite mirror back and fourth as it ascends.

It's a tough one really (if the goal is to be consistent with the Super Mario series graphics).  You'll just have to try a few different approaches to see what works best.

Can you replace the Gyromite music with music from different types of Mario games that would fit in nicely on the current board you are on.....like Mario Bros world 1 level 2.

[JUg]

I was thinking about that, but I don't know much about 6502 ASM and I hear that the music coding of GYROMITE would have to be coded the same way as Super marios Bros. to be able to transfer it. So yeah ... not gonna happen unless someone with intense ASM skills does it.

[Quick Curly]

Well, music can always be considered and looked at later. Sometimes it helps to focus on modifying the main stuff first, usually the levels.
How is the level editing coming along? Are you able to figure out and understand the relevant data for the other levels besides Phase 01, and how is everything progressing so far?
Also, don't feel rushed. Take your time. We can all wait.

I like how you used the information to help change the rope to the vine. Well done!
No worries. You're doing well, and your project is coming together.
If you have anymore questions, please feel free to ask, and hopefully I or someone else will be able to help. Keep it up!

Yeah, I actually had to rework from scratch because I modified a code that crashed the game when it started phase 01. Right now I'm focusing on the graphics and I've changed the main character. It's now a Koopa and the hack will be called Super Koopamite. Once I'm satisfied with it all the tile changes, I will start working on the levels. I'm still not sure if I should keep the Turnip. It's too bad I can't find a way to make it 4 tiles instead of 2 and the fact that it uses 2 different palettes is odd to me.



So now the spinnies have a climbing animation sprite and so does the Koopa. Altough I'm not satisfied with how the climbing Koopa looks only in one direction, I'll try to fix it later if I find a better way.

Interesting decision to change and it definitely feels like a fresh idea. What made you decide to change.

Well, I was thinking about a story for this hack ... and just saying Bowser found a new way to mess with Mario seemed dull. So I figured I would put the Koopas in some sort of training session because bowser is fed up with them not beating mario and he has them pick up dynamites (subject to change) so they can be faster. You know, simple 1980's game logic ;P
