Hacking EZFlash Omega Skins

Today I used the tool and created a skin.
My first try. Black and gray skin.

Out of curiosity, how does one generate the proper checksum to get the program to identify a custom kernel?

hey what's up man? i made an account just to communicate with you about this. So i just got my omega cart yesterday, it's my first flash cart and immediately i was kinda irritated by the graphics. i'm a professional designer myself so i made a few designs from your zip file as a template, and used the latest kernal fw as the base, it made the graphics kinda all jank, so i just went back and installed your mod instead, which give me a clean layout again, but the games are not in alphabetical order anymore, is there a way to sort out the sorting? i'm not sure why your mod did that, but i do like the font a lot more! i don't know why whenever i try to modify your fw from the skinner app, it makes the images and placement very off after i export it and update it on the flash cart! so as of now i can only use your kernel without any personal modification for now, do you know why i'm having those issues?

I love your mod! i just installed it and it fixed a lot of small issues i had with other modifications to the kernel, may i ask how you did it? because i've made a few images using the same dimensions and specs as the included files, used the skinner app to "save" the kernel as a file, then updated with it on my flash cart, but it always looks off, like UI elements are in the wrong place and stuff

i really want to make the font in to helvetica, as it's my favorite font and the most appealing to me, how do you recommend i do that? would i just try to replicate your text font img, but with that font instead? in photoshop? then export and load it up? i feel like that would be the assumed way to do it, but idk it just sounds wrong lol

It's really easy but not best way.

I take every definition i have, take the file and fill the regions where data is replaceable with zeroes.

then i calculate the crc. If it does not match, i take the next definition with the loaded file and so on.

If you have an Error Message like "Error loading File, no definitions found for file. Please create correct definition in definitions.xml or ask someone to create one. Alternate is using supported and defined files. Load file anyway to force a layout?"

Do NOT PROCEED as i mentioned in my first Post. Parts of the Firmware could be overwritten by image Data - you could Damage your Flas Cart!

In this case you do not have the current definitions.xml i posted several weeks ago for current firmware, or you are using a new and unknown Firmware.
If none of this is the fact, then i do not know what the problem is.
Sorting is integreated in a newer firmware. so sure you edited the new current 1.04 6.0 firmware?


And yes, you may have to edit your font with photoshop or another picture editing software.
If you good in programming you can write your own program to generate a char map.

Each Char (ascii map) is 8 by 12 pixels in Size.
The Unicode Char Map with Chinese Chars is doubled in Width (16x12 pixels per Char)

I just found this thread and it's a lifesaver. Made my own skin just now; It's not the greatest, but I figured I'd share it to give people options.

Does not work. My Theme looks the same as the old one.

I created a new definitions.xml for use with the new kernel that dropped a few days ago, see below. I don't know how to generate the CRC the skinning program expects, but you can force the layout and it will work just fine.

I also created my own dark theme that features darker UI colors, a cleaner typeface, and a modified top menu that is based off of FW 6 Kernel 1.05. I included the theme and an action shot below.

What is the proper chksum for the lastest firmware available on http://www.ezflash.cn/download/ (Kernel 1.05 and Firmware 6.0)
I can't seem to figure out how to calculate it. It's not a regular crc32 (even though it looks like)

Сreate please a new definitions.xml for FW7 Kernel 1.06

Hello there,

i've uploaded the files to my own server. You can download the file and the tool there:
https://dl.t5b6.de/uvSkinner/

i've added the previous and current firmware support.

> sha1sum ezkernel.bin

acd5717637a77e916c0d0143013126a016f01985  ezkernel.bin

even this is incorrect.

As i mentioned many posts before, the checksum is calculated with a correct set of all images.
My Software will blank out all these images and calculates a default CRC32 checksum.

if you have correct addresses of all images and their sizes, you can edit the definitions.xml.
then you'll have to start the skinner app, confirm that you will choose manual layout. In the menu shown above, you can choose your edited layout. If all seems to be correct, you can transfer the checksum to the definitions.xml. At this point the app will choose the correct layout.
This is the only way i found out, which will work even with modified firmwares.

Thank you for this wonderful tool. Just discovered it used it and it works perfectly!

@t5b6de is there anyway to have users update Goomba to latest or do u have to do that?

http://www.dwedit.org/dwedit_board/viewtopic.php?id=728

 

[t5b6de]

in theory I can add thatsupport. but we have to find out if there is any length field or so, because that firmware must know how many days it has to copy to the sram before copying the games behind the goomba image..

if you made it wrong you can corrupt your ez omega

The cart itself or the mSD card might get corrupt?

 

[t5b6de]

cart, ez omega as I mentioned before

@Shadow#1 i just downloaded the sources of the ezflash kernel and included the new version of goomba.
And it's not compatible currently.
For most games it just crashes and for others they crash if you try to leave the menu.

So probably you will just have to wait until the ezflash guys implement support for this goomba version.
