Hacking New Theme for EZ-Flash Omega!

[BETA215]

The only change is replacing Goomba with Jagoomba anyway, which is a 'feature' SimpleDE already had. So yeah, changing the number would be more than enough, if it was actually even needed.

yeah it probably wasn't all too needed but the alert that "hey you need to update your fpga firm" was probably a good call anyway so that people don't say that this kernel has issues long resolved

I bougth a ez flash omega definitive edition, i tried to play metroid zero mission, when i make a save state and try to load it, the game Start to make an annoying sound like a whistle, i have a sd of 2gb in fat, then i formated in fat32, it didn't solve the problem after that i change de sdcard to 16gb in fat32 cluster 32kb and the same problem persists, then i installed the cfw of stereophonick and nothing happen, how can i solve the problem?

Taken directly from the ez flash manual:

"Note: Save state on physical hardware is different from the same name on computer emulators and is limited by hardware restrictions, such a read and write restrictions on various registers. On the other hand, the emulator on the computer simulates the hardware through software and has full read/write access to the registers.

Therefore the use of save states on physical hardware will be accompanied by some graphics glitches, music noise and other issues, and the high frequency of access to save state (save/load) may cause a crash."

The whistle is just an issue with the way save states work on the cartridge and the fact it's not always able to load the game correctly when using them. You're better off not bothering with them if you can help it, you might find the game is actually unplayable after loading in some cases. It's kind of stupid they're even included really but I guess it's there to fill out the features list.

Now if the other issue you're saying you have is you can't load the save state after changing the fw, that's likely because you changed the FW. The save state is a complete system snapshot, it's of everything running including the fw on the cartridge, not just the game itself, so having something different running on it will mean the old state isn't applicable anymore because parts of your system are now running differently.

Like the manual implies, save states on this hardware aren't as simple as emulator ones and you can't just move it around as easily as you can with emulator states. You'll also find states made on an emulator aren't compatible with the ez flash too, even though regular saves are in the right format

all an update would do here is change a number since i don't have the ROM space to include the FPGA firmware in SimpleDE. it's a load of crap, i know. but i'll get that out and swapped here when i get a chance

Update v1.5 (Definitive Edition ONLY):
- Reworked internal logic for detecting FW updates. Still cannot update from Simple. The kernel still instructs you to update with the official kernel.

Simple will tell you to update if your cartridge is:
- Rev A (LX9): Below firmware 5
- Rev B (LX16): Below firmware 7

Original Omega users do not need to update.

Lemme know if your cartridge erroneously is/isn't telling you to update, because I do not have a Rev B cartridge. This new logic does not write to the FPGA so there's no risk of bricking.

Thanks for the update! I have a Rev B and confirm it works:

 

[f3bandit]

EZ-Flash Omega DE update Kernel 1.05 and firmware 7.0 DOWNLOAD. Applicable to both Rev.A and Rev.B
this fixes sleep and mode B on the analogue pocket on rev B carts not on rev A
Guess I'll order a rev B
reddit post
official fw

 

[Dante2405]

I have rev B and it works. Thanks

 

[TonioGela]

Thanks for the update! I have a Rev B and confirm it works:

So what's the procedure with Rev B? Update using the newly released stock firmware and then reapply the last build of Simple that Stero posted?

Idon't believe simple light or simpleDE have been updated yet

 

[Sterophonick]

Correct. Use the official kernel to update the firmware and then reapply my kernel

 

[TonioGela]

Thanks @Sterophonick. I'll like to have a look at the code of the kernel, I've never done embedded C (on any kind of C that ends up running on a device that's not a full-fledged CPU) so I'm really curious.

 

[EZ-Flash2]

Correct. Use the official kernel to update the firmware and then reapply my kernel

we have a separated firmware updater.

Oh, that's lovely then!

When I try to boot Pokemon Crystal it gives me the warning that I need to do it on a Gameboy Color and the game isn't compatible. I installed the firmware all the while following the instructions so I do not understand why this doesn't work.

Did some trial and error while I waited for an answer and the No-Intro compliant rom works. Perhaps a warning should be added to the TXT file of the latest release or at least some note of caution about the quality of the roms ? Also just curious, why isn't the latest version on the release page of the github ?

It was noted in the official download page.

I was having trouble saving in Pokémon Yellow. I would save ingame, wait ten seconds and then create a savestate, wait ten more seconds and the L+R > exit and then shutdown the GBA but at least two out of three times the saves would be gone and I would end up losing hours of progress

So I did the EZ-Flash Omega SD activity LED mod and I have noticed that the LED only flashes and signals for SD Card activity when I save/load a savestate and when booting the game. When I save ingame the LED doesn't flash even if I wait more than ten seconds. Is this because when playing GB/GBC games it isn't saving directly to the SD but rather saving "inside" the emulator? Does it make sense?

I also read here in another thread that with Jagoomba, even after waiting ten seconds after saving doing L+R > exit instead of rebooting the GBA causes the saves to become corrupt, both savestate and regular save. I found this to be true, after stopping doing L+R > exit when saving, I haven't lost the saves.

The question here is what is the best method to decrease the risk of losing saves?
A) Savestate, wait for LED, save ingame, wait ten seconds, turn off GBA.
B) Save ingame, wait ten seconds, savestate, wait for LED, turn off GBA.

Also @Sterophonick, how does the save backup feature works exactly? I noticed that when my saves get corrupted, I only have the saves from the evening the day before. It goes like this:

I play a little bit in the morning before work, save and shutdown, come back to play before lunch break ends and I notice the saves are gone. I go backup them from the backup folder and the saves are from the day before. Does this mean it backups the saves at boot? With this I can only conclude that after saving either via A) or B), another step is needed which is turn on the console, wait for LED to stop flashing and then turn off?

Sorry for the long post but I'm new-ish to this gameboy and pokémon and etc things. I might not be finding out anything new

I read your steps and you should press L+R once before finally shutting down, do nothing else, wait a few seconds and shut down directly.

*update*
Just in case any other analogue pocket owners out there have a "EZ-Flash Omega DE Revision B" as well.
I can confirm the library function works perfectly with the Omega DE Revision B running Simple-light-DE /
Simple-dark-DE and the RevB_update_FW7.zip from EZ-Flash. and of course the sleep and mode B function. It sucks I have
to buy the newer Revision B of the Omega DE from EZ-Flash, But I guess I'll use my old Revision A on my
Gameboy player for my modded GameCube.

Where can i download the theme of simple de for kernel 1.5 fw 7? Please i am noob on the scene, i update the kernel and fw, when i load a save state of metroid zero mission and fusión apart of the whistle now i get a black screen please ez flash Team solve that problem i have a ez flash omega definitive edition rev b

This is the SimpleDE kernel for the ezflash omega DE. extract the contents to the root of you sdcard insert in the omega DE cart. once done copying the files to you sdcard there are two files that are important. ezkernelnew-dark.bin and ezkernelnew-light.bin. rename the one you want to use to ezkernelnew.bin.
boot the GBA while holding the right shoulder button and follow the onscreen instructions. once finished power off and then on the GBA. If you get stuck read the !!!!!!!!!IMPORTANT!!!!!!!!!!!.TXT file included in the simpleDE.zip
then look if you have a rev A or B omega DE cart

If you have a rev B cart download and extract the file that has a .gba file extension to the root of the sdcard
and run it like any other gba game and follow the instructions on screen as before power cycle the system again.

Can confirm this works well. Save, press L+R wait for activity LED and shut down.

Is there any reason the LED doesn't show activity in Jagoomba?
