Hacking EZ-FLASH OMEGA test flight

[EZ-Flash2]

1. Game console type: Game Boy Micro OXY-001 Famicom Edition
2. Firmware version: 5 (displayed 99 in menu)
3. Kernel version: T2 (can't be tested on T3 due to 1st bug above)
4. MicroSD type: Samsung Pro 32Go (gray one) 90MB/s read 80MB/s write UHS-I Class 3
5. MicroSD format: FAT32
6. MicroSD cluster size or allocation unit size: 32K
7. Bug description: Omega menu breaks the ingame display in some games as Top Gear Rally
8. Bug reproduce steps:
- Launch Top Gear Rally with BOOT WITH ADDON mode (here Save, Reset and Sleep functions activated)
- Display the Omega menu with L + R + Start
- Exit this menu
- Notice that the display is now broken
Note: Seems to be here a context loss. On a SuperCard MiniSD, the context is lost as well if trying to load a save (created during a race) outside a race because the "3D" engine has not been initialized yet but works fine if the save is loaded after the game engine is initialized through a race on the SuperCard. May be a lead to explore.

bug 1: fixed
bug 2: I forgot to enlist the know issue which 1.03T3 does not compatible with the RTS file created by previous kernel.
bug 3: Top Gear Rally uses a dynamic coordinate system in race scene. it uses the BG2 register to control the camera. they are WRITE only registers. We can not read their value and backup them to restore back. But the in-game menu needs initial these registers to output a correct in-game menu screen. or you will get a stretched or rotated in-game menu screen if not initial the registers. to avoid the issue. try to pop up the in-game menu in the NONE-3D scenes.

bug 1: Good news.
bug 2: No problem, good to know.
bug 3: Do you know why it works on SuperCard (only if RTS is loaded after initializing a race though)? As you may guess, displaying the popup is much more needed through a race (to be able to cheat by reloading a RTS). But I can live without that though.

Another issue (with games that are non official or not 4/8/16/32 MB size):

1. Game console type: Game Boy Micro OXY-001 Famicom Edition
2. Firmware version: 5 (displayed 99 in menu)
3. Kernel version: T2 or 3
4. MicroSD type: Samsung Pro 32Go (gray one) 90MB/s read 80MB/s write UHS-I Class 3
5. MicroSD format: FAT32
6. MicroSD cluster size or allocation unit size: 32K
7. Bug description: Games as http://gbadev.org/demos.php?showinfo=1279Another World or Bust A Move cannot be patched, nothing happens ingame when pressing L+R+Start
8. Bug reproduce steps:
- Launch http://gbadev.org/demos.php?showinfo=1279Another World or Bust A Move with BOOT WITH ADDON mode
- Once the game is launched, press L+R+Start
- Notice that nothing happens

I don't know if those games are already patched in a way, maybe that's why it prevents them from being patched.

The games which you mentioned are homebrew games, they are not supported by "BOOT WITH ADDON", the function only supports commercial games.

Ok no problem, that's what I first thought but was unsure.

i don't have an omega, i have a ez flash iv. I can install the same??

 

[dcervi]

i don't have an omega, i have a ez flash iv. I can install the same??

Then, why are you asking on a thread dedicated to the Omega?

[EZ-Flash2]

Some modded backlit original GBA will cause the NOR on EZ4 unusable, the solution is revert the GBA to unmodified or change another console.

Please stop hijacking threads about the omega when your issue is about the ezflash IV.
Create a new thread about your issue and provide more details.

Which gba are you using? What kind of batteries? Which games? How does "doesn't work" manifest for you?

Why do you shout like this?

And yes, that's the wrong topic.

Nice!

Can't wait for the new release.

 

[Aliogeek]

Hey !

Can you please add the possibility to enable RTC only on the games that require it (with the possibility to force it for certain hack roms) ? It will be more precise than a global switch and will allow to save power for the games which never use Rtc.

I am never quite sure why people want to play those first person shooters that the GBA got, especially not the ones made for the console as opposed to ports of classic "Doom clones", but to each their own.

Anyway I would not hold my breath for a fix for that. We could probably have a look at the source of the loader and then reference it against http://problemkaputt.de/gbatek.htm#lcdiobgrotationscaling and figure out what is going on. The answer most likely though is "3d games on the GBA require some fairly creative graphics coding, the hack that the cart uses to add a menu probably breaks that as almost all other games will do it the 'normal' way. Any fix is then going to have to be a thing that is specific to that game and that is a rabbit hole nobody wants to go down right now.". It is not quite the same reason you will be told to move to a new area to fix graphics and audio issues when using savestates but it is close, also that might well fix it.

Bug report
Final Fantasy Tactics Advance in-battle saves are supposed to be automatically deleted after being resumed, but they're not.

Specs
1. Game console type: AGB-001
2. Firmware version: 5
3. Kernel version: 1.03
4. MicroSD type: Unbranded 16GB MicroSD HC class 10
5. MicroSD format: FAT32
6. MicroSD cluster size or allocation unit size: 8192
7. Bug description: Final Fantasy Tactics Advance in-battle saves are not deleted after being resumed
8. Bug reproduce steps: see below

Bug reproduction steps
1. Start Final Fantasy Tactics Advance on clean boot (either from micro SD or NOR). I'm using Final Fantasy Tactics Advance (U) [!].gba (SHA1 4ac05441f4de70a4ec3dd932116346c61b8783d9) from the No-Intro romset.
2. Enter a battle.
3. During the battle, press the B button until the character menu (the menu with "Move," "Action," "Wait," and "Status" on the lower-right side of the screen) is closed. Then press the start button to open the system menu and select "Save Now" to write an in-battle save.
4. After returning to title menu, select "Saved game" and then "Resume battle" to load the in-battle save.
5. Reset the game and return to the title screen. Select "Saved game" and observe that the "Resume battle" option is still available; the in-battle save was not properly deleted.

Feature request
Is this the proper place to put feature requests too? I want to turn off the EZ-Flash splash screen that comes after the GBA BIOS logo.
