Super Gameboy emulation?

ok so i have made an overlay and instructions on how to make the gb emulator look like a super gameboy.

to startdownload this image and name it supergb.png. place it in /opt/retropie/emulators/retroarch/overlays/

create a file in /opt/retropie/emulators/retroarch/overlays/ called supergb.cfg and add this info to it.

overlays = 1
overlay0_overlay = supergb.png
overlay0_full_screen = true
overlay0_descs = 0

now open /opt/retropie/configs/gb/retroarch.cfg and add this info in the middle somewhere.

video_fullscreen_x = 1920
video_fullscreen_y = 1080
custom_viewport_width = 779
custom_viewport_height = 700
custom_viewport_x = 579
custom_viewport_y = 189
aspect_ratio_index = 22
video_smooth = true
input_overlay = /opt/retropie/emulators/retroarch/overlays/supergb.cfg
input_overlay_enable = true

now select a gameboy game and make sure tha lr-gambatte is the emulator you are using. once in the game go into the rgui. (select + xis the default) go into quick menu.
go into options and change gb colorization to internal. now press select + x or whatever you used to get into the menu to get back into the game. now it should look like a super gameboy. this is the best i could do to make it look like a super gameboy for you.

@edmaul69

in the lr-gambatte gameboy emulator you can change it to color.

Unfortunately, that only makes use of the color information found in the GameBoy Color hardware for Nintendo R&D1 games. Super GameBoy titles have their own specialized color pallets that can only be accessed with GBC/SNES hybrid emulation.

@XVO

I don't believe there is currently a way in RetroPie to utilize the Super GameBoy borders or color information, which is especially a shame for 'Donkey Kong' and 'Space Invaders'.

[lilbud]

@mediamogul Especially Space Invaders GB, which was a whole different game on the Super Game Boy

[mediamogul]

@lilbud

Exactly. The Super GameBoy is the only way to access that title. It's an nearly arcade perfect version of the arcade, right down to the back glass, which admittedly is mitigated by the fact that we can recreate the same thing in one of the MAMEs, but it's still an neat trick to pull off.

[edmaul69]

@mediamogul i know i cant recreate animations or special games backgrounds, but i think i can make all of the borders. (Not animated of course). So i think i am still going to create all of them so people can use them. Starting with the one i already posted here.

@edmaul69

So i think i am still create all of them so people can use them.

I think it's a very good idea and the default border is a great start.

I know it's old but I wanted to comment, I find this incredible that we have every other kind of Nintendo emulation except this. I mean, we even have some of Nintendo's Game and Watch, some weird rom patch like Top Gear 3000 on SNES and yet not emulator for a Super Gameboy.

Come on guys, makes our kids dream come true!!! >_<

I'm pretty sure I'm not alone. Take my money and keep the glory!

[mediamogul]

@Fultos

It would require adding the Bsnes libretro core and normally the Raspberry Pi isn't powerful enough to run it. However, I wonder if this particular use case wouldn't be a little less demanding? If it did work, the launch option could be added just to GameBoy.

retroarch -L {path to bsnes core} {path to snes rom} --subsystem sgb {path to gb rom}

If anyone can point me in the right direction for information on compiling just a single libretro core, I'll be happy to try and test this out.

[mediamogul]

I found this...

https://github.com/libretro/RetroArch/wiki/Compilation-guide-(Linux)#building-libretro-cores

I'll start looking into it sometime soon.

I would LOVE to see this, since so many of the games I have would look so much better.

For one, in the GB version of Mighty Morphin Power Rangers (and MMPR: The Movie), only through Super Game Boy does the game give a character-specific palette, making the playable characters more distinctive. For example, when you play the Red Ranger, your sprite is red and as the Blue Ranger, your sprite is blue.

Also, many games play much better, if not just sound and/or look better, in SGB mode.

And iirc, many PC-based emulators (VisualBoy Advance) feature this.

[mediamogul]

Anyone happen to know if I can just use the pre-compiled nightly binaries below?

https://buildbot.libretro.com/nightly/linux/armhf/latest/

I'm turning in for the night, but I got all the Bsnes cores listed there and tomorrow, unless I hear otherwise, I'll try the performance cores first. If they work out, I'll move on to accuracy.

[mediamogul]

Well, I've been working on this off and on all day and it seems close to working, but I've hit a brick wall.

My launch command is:

/opt/retropie/emulators/retroarch/bin/retroarch -L /home/pi/custom-binaries/lr-bsnes/bsnes_performance_libretro.so --verbose --config /opt/retropie/configs/gb/retroarch.cfg /home/pi/custom-binaries/lr-bsnes/Super\ Game\ Boy\ \(World\)\ \(Rev\ 2\).sfc --subsystem sgb "/home/pi/RetroPie/roms/gb/Donkey Kong (JUE) (v1.1).zip"

It begins to launch and it gets pretty far:

The problem seems to be at the bottom where it has a segmentation fault and then exits:

/opt/retropie/supplementary/runcommand/runcommand.sh: line 961:  2421 Segmentation fault      /opt/retropie/emulators/retroarch/bin/retroarch -L /home/pi/custom-binaries/lr-bsnes/bsnes_performance_libretro.so --verbose --config /opt/retropie/configs/gb/retroarch.cfg /home/pi/custom-binaries/lr-bsnes/Super\ Game\ Boy\ \(World\)\ \(Rev\ 2\).sfc --subsystem sgb "/home/pi/RetroPie/roms/gb/Donkey Kong (JUE) (v1.1).zip" --appendconfig /dev/shm/retroarch.cfg

Without knowing more about what this really means, I'm at an impasse for now.

Well, I'm satisfied now that this isn't going to work. I was finally able to get lr-bsnes-accuracy to reliably launch without crashing, only to be met with a black screen each time. After a little more research as to why this might be, I discovered that the Super GameBoy subsystem in RetroArch is simply broken on all Linux variants. What's more is that they've looked into it and have no idea why this is the case. So, unfortunately, Super GameBoy emulation is not happening on Raspberry RetroPie for the foreseeable future, but at least it won't be for a lack of trying.

Super GameBoy is the new Sega Saturn......... noooooooooo! :P

@felleg

Ha! That may be more correct than you know. Even if it had run, there's no guarantee that lr-bsnes-accuracy would have operated at more than a few frames per second on the Pi.

@felleg lol

[Fultos]

@mediamogul at least you tried something :D

I'm glad someone took a fresh look at it, it seems so complicated to create an inception of emulation :P

I mean there's a couple of gameboy games which are not emulated at their full potential since it's a really-hard-tu-pull-off project.

@Fultos

My hacked Wii runs an older version of VBA-M and emulates the Super GameBoy features very well. Support could even be found in lr-vba-next sometime before 2012. It seems to be an ability that's just falling between the cracks for the Pi at the moment. However, I'm sure the pieces will all come together again sometime in the future.

Any update on this? As @mediamogul mentioned, I tried several games on the latest VBA-M Windows build from Github (2e8bee1) and found most of them run well with SGB and SGB2 (unable to play arcade version of Space Invader though). Wonder if lr-vba-next will add back this feature.
