(Suggestion) VisualBoyAdvance old version lr core for Super Game Boy

matchaman

I'm afraid not. This is exclusive for bsnes/higan and it's great for PC setups but the core is too highly demanding to be available for the Pi.

Therefore, SGB emulation remains uncovered for the Pi with the only solution being older versions of the VBA core (GB/GBC module) to be ported in the future.

@matchaman The other option is if someone makes a separate emulator just for the raspberry pi.

matchaman

Not just for the Pi. Other low-powered devices would benefit from such a port core, since bsnes/higan is the only current option and it requires a modern PC.

@matchaman I am actually thinking of creating a super gameboy emulator but I would need help with how the Super GameBoy worked( can you help me with this?)

matchaman

On a technical aspect, I'm afraid I don't know how it works.

All I know is that the SGB is a complete DMG in a cartridge along with some enhancement chips that transfer additional SNES-specific data (frames around games or extra ROM features such as more colours and rarely SPC audio).

I guess that some basic SNES hardware knowledge is required along with understanding how and where the SGB content is contained within each ROM. It can't be very demanding since it was covered in VBA in HLE and worked perfectly minus a few titles that contained a full SNES-level enhancement ROM.

I'd love to play some 'Donkey Kong '94' in color. Super GameBoy emulation is one of the few remaining areas where the Pi comes up short unnecessarily. However, requests do come up often enough to believe that someone with the knowledge to do so will eventually rectify the situation.

matchaman

@mediamogul VBA wouldn't cover this particular title, unfortunately. It would however emulate 99% of the SGB enhanced titles, excluding those that contained a 16-bit ROM such as Donkey Kong "94" and Space Invaders. However, I don't see why none attempts to port/transcode those into SNES ROMs. I guess because bsnes/higan works perfectly for PCs but I'm pretty sure it's not very compliated to get stand-alone ROMs.

I'm able to play DK '94 in color using Visual Boy Advance GX on my hacked Wii. Is this just a limitation with the libretro implementation?

matchaman

Does DK 94 have all its features? That's even better news! As for VBA for the Wii, yes, that's exactly the point of this thread :)

Older versions of VBA supported SGB emulation, while this feature (along with all GB/GBC emulation) has been dropped on the VBA libretro core because gambatte is more accure.

Gambatte however lacks SGB support, therefore the Pi (and all other low-powered devices that can't run bsnes/higan) is left with no option for SGB emulation.

You can't display the border, but the color pallet displays just fine.
