Hacking EZflash Omega Fan Translation Shinchan not working

Bonnom · Oct 22, 2020

I tried to play a english fan translation of "Shinchan Aventuras en Cineland".
The games works great on mGBA and even on my SuperCard SD flashcart but on ezflash omega it doesn't work properly.
All the english text is replaced with a bunch of "V"s and the screen becomes completely black when beginning a new game.

Does someone have a similar problem with Romhacks/fan translations games not working on the ezflash omega?

While I tried a few ROM hacks and translations without issues (Mother 1,2 and 3, Pokemon Chapter Red, Fire Emblem for example), I haven't played any Shinchan Game ever.
Make sure you "clean boot" the ROM on the Omega and see if the issue persists.

EDIT: I assume it's this translation?

Thanks for your reply! Clean boot does not work.

I also tried other fan translation and they worked fine but I wonder why this one doesn't work on my ezflash omega since it does work on the crappy supercard sd and mGBA.
The github page is indeed the fan translation that I used. I was wondering if someone knows what causes this problem, since the translation is opensource I might be able to fix it!

Change your Save type from "Auto" to "Flash64" or "Flash128" at the menu before you launch the "clean boot"

But saving doesnt work. -.-''

Only way to play seems to be using the flashcart save state.

I can confirm that the bug appears on the Definitive Edition as well.

If the ROM is save patched with GBATA and then the save type is set to SRAM 32kb, the game doesn't have these bugs and can save correctly.

EDIT: Had a thought about what the cause of this problem might be. The unpatched game is 16MB and uses EEPROM saving. This means 0x08xxxxxx addresses contain the ROM and 0x09xxxxxx addresses are used for communication with the EEPROM. The translation patch appends the new graphics and text to the ROM, meaning they are in the 0x09xxxxxx region of GBA memory. The EZ Flash probably has made this part of ROM inaccessible and is continuing to emulate EEPROM here. If EEPROM is disabled, then this ROM suddenly becomes usable again.

I'd be interested to know if this romhack works on an Everdrive GBA.

How did you set the save type to specifically 32kB? It only generates 8kb save file with my patched rom using GBATA.

What's odd is using mGBA with "auto" save setting, this automatically sets the save file to SRAM and it saves without any issue, but not on my EZ Flash Omega.

Do let me know how you manage to set it and get it work on your EZ Flash

Thanks!

The save type must be set to SRAM on your EZ Flash. You cannot choose a patch in GBATA, just patch it with the default.

mGBA's automatic save detection and save emulation works different to the EZ flash so that makes sense.

Thanks for the reply. I tested and it worked like you stated.

Finally I can play on my handheld!
