[RESOLVED] Game Boy Advanced bios warning issues....

Hi all! Despite having the proper bios in the C:\RetroBat\bios folder (gba_bios.bin with correct md5 checksum), I'm still getting a warning from retrobat when I attempt to play GBA games. (Warning: The system has missing bios file(s) and the game may not work correctly). I can hit "launch anyway" and the game works, but for the life of me I can't figure out why I'm still getting the warning. My GB and GBC systems work fine, no warning. I have searched through the wiki, faq, and forums, and as far as I know I'm doing everything correct?

Thoughts?

Hello,

You need all bioses:
- gb
- gbc
- sgb
- gba

I don't know why but gba system checks for these 4...

Thanks for responding @tartifless ! To make sure I'm following, you mean these bios here stated on the original first gen GB RB wiki?
gb_bios.bin
gbc_bios.bin
sgb_boot.bin
sgb2_boot.bin
SGB1.sfc
SGB2.sfc

If not, I'm not sure what SGB stands for?

Hello,

Only the 3 first ones you have listed plus the gba_bios.

Okay, sorry, took me a bit to get back to this, few updates. I currently have the following md5 checked bios(s) in my retrobat/bios folder:
gb_bios.bin
gbc_bios.bin
sgb_boot.bin
sgb2_boot.bin
SGB1.sfc
SGB2.sfc
gba_bios.bin

When i try to start a GBA game, I still get the warning it's missing files, but if I click okay, as mentioned before, it will go ahead and play. If I go into the emulators folder manually and start up mGBA.exe, i can load the games fine and no warnings. So I'm not sure what exactly is causing ES to throw that warning since all the bios are there and the games work?

Use the bios checker within RetroBat and it will tell you

Ah! Didn't know that existed, will be super handy for other systems! Thanks for all your help @tartifless !
