GB core: have to manually select BIOS every time. GBC is automatic. #23

_Analogue Pocket w/ 1.1-beta-4 (2022-09-28) firmware. Spiritualized_GB_1.3.0_2022_0825.

When using the GB core, you have to manually choose the GB bios every single time you load a GB game. The GBC core does this automatically. Can we make GB core work the same way? Super small thing I know, but would def streamline the process.

As to why... since people love to ask "why?" lol... This AWESOME project (thank you for it!!!) has 2x .zip files in the repo - so if you want you can have separate cores for GB and GBC (which will also play GB games). I love that as I want to keep my GB games separate from my GBC games. I also like how while playing GB games using gb_bios.bin it makes them green tinted like a real GB is. That isn't possible to do in the GBC core (while playing GB games), even if you hold Left+South button, that only makes the games grayscale - no green tint. This might change when/if Analogue adds screen modes to OpenFPGA, but for now this is what we have to work with...

This happens when your GB bios is named incorrectly. Make sure your BG bios is named dmg_bios.bin, and it should no longer require you to manually select it anymore.

Great, I'll try that. Thanks!

Perfect, worked for me!

Fantastic tip, for anyone who finds this issue :). Thank you.

And thanks for this fantastic core.

If the readme can be updated to include this information, would be great.
