Hacking What the firetruck?

[Deleted-236924]

I've noticed a pretty weird issue.
It happened to me multiple times when playing Super Mario Advance 3 (Yoshi's Island)

The problem happened at world 2-8. I would randomly get the rom reset to what seems like the GBA BIOS' splash screen.
Here's a picture to better show what I mean:

What the firetruck indeed.

This happened to my brother once, he reformatted his card, and after that the issue got solved.
Can't remember what game caused it with him though.

Is there even a GBA BIOS in NDS-GBA?
Or part of GBA BIOS in the rom itself?

It normally shouldn't be supposed to show that splash screen without GBA BIOS.

i'm sure there is, how else could it play GBA games?

It is possible to run roms on an emulator without the system's bios.
Just look at NO$GBA or VBA (Examples)
You can run the NDS or GBA roms without actually having the bios for the system.
Same for DeSmuME, same for pretty much every other emulator

An even better example would be GB emulators.
Even though the GBC BIOS have been dumped, none of the emulators actually support it. Yet they can run the roms.

im sorry for doubting u but do u have any proof of that? i know of a few emulators that require the BIOS, i just assumed those emulators have it included

Why would you need proof?
Just try VBA, NO$GBA, DeSmuME, TGB-Dual, BGB, etc. without the system's BIOS.

If there was a BIOS, it would most certainly be in the .plg file.
But if that was the case, I'm pretty sure we should be seeing that splash screen upon booting a rom.

well i have an android gba emulator that requires the BIOS but there's no splash screen at the beginning

There is a BIOS for the emulator on Supercard DStwo. I know for sure that GPSP(GBA emulator for PSP) required a BIOS and this is a port of it so I think there is a BIOS.

Well I guess I got my answer then.

the bios is inside the plugin file, it's hard coded into the emulator, so to speak

sure, there is no single file, but the code needed is there, in the plugin file
