Hacking [EZ Flash Omega DE ] Cannot boot with addon

[aokiseiichiro]

Hi,

I have an issue for GBA roms with "Boot With Addon" function on my EZ Flash Omega DE : never mind selected options on system configuration (Save State Only, Save State + Sleep, Save State + Reset, Sleep Only...), if I launch a GBA game with addon, I have a black screen, then a white screen with creepy noise.

Tested with many games : Megaman Zero 3, Darius R

Tried with many configuration (with / without Fast System, with / without RTC, writin to NOR addon...).

No problem with Clean Boot on GBA games (and GB/GBC games).


Here is my configuration :

- Kernel 1.03 and firmware 4.0
- GPA SP
- IPS V2 screen
- New battery

Please could you help me with this issue ?

Thanks !

check the rom hash with known rom list.

or turn off fast patch engine.

Already tried do turn off fast patch engine (that's I would to say in my first post by "with / without Fast System" ^^).

Here are hash codes (get from Hasher-js online):

Megaman Zero 3 :

Database match: Mega Man Zero 3 (Europe)
Database: No-Intro: Game Boy Advance (v. 20210227-023848)
File/ROM SHA-1: EDFCB606136951374F24AA8FD7E5B4E710300301
File/ROM CRC32: B099577F


Darius R :

Database match: not found
Database: No-Intro: Game Boy Advance (v. 20210227-023848)
File/ROM SHA-1: 15F12196355054D9172A42ABDB021EB2D07F1536
File/ROM CRC32: C0A01CAA


Darius seems KO but Megaman is OK no ? So this is not the cause. :/

The case of Darius R makes me feel a doubt, because I've done many test with it.

So I made new tests.

Fast Patch Engine Off
Game RTC On
Addon options : Reset + Save

Darius R - Boot with addon = KO
Mega Man Zero 3 - Boot with addon = OK ! Menu appears well with L+R+Start.


Thanks for your help

Your copy of Darius is known to be a bad dump, the SHA-1 is the checksum of the introed ROM (see https://datomatic.no-intro.org/index.php?page=show_record&s=23&n=0787).

You're going to need to find a clean rom with the SHA-1 of EEAF2CB1CBC8E9B447FF37429EF7F08A2D6559F7
