The Game Boy emulation core is courtesy of gambatte, and excellent, accuracy-focused, open source, and lightning fast Game Boy Color emulator. Now I know what you're thinking, using a Game Boy Color emulator with the Super Game Boy? The truth is, gambatte was just such an amazingly perfect fit that nothing else compared. I fully believe that even as a CGB emulator, gambatte will do a better job than any pure DMG emulator could.

The emulation of the ICD2 chip (aka the Super Game Boy) was fully reverse engineered by myself. Eventually I'll get an updated document put up explaining how it works.

The next question might be, "why emulate the Super Game Boy when existing Game Boy emulators do?"; well, they can only simulate part of the SGB. Features such as custom SNES sound effects, hand-drawn borders, multi-tap support and custom SNES code execution can only be accomplished by a true SNES emulator. Space Invaders is perhaps the most impressive demonstration, as it contains an entire SNES game embedded inside the Game Boy cartridge.

bsnes' SGB emulation supports virtually every command, full sound mixing from both the SNES and Game Boy sides, both BIOS revisions, etc. The only thing that is not fully functional yet is the multi-player support, but it should be in due time. Save state support is also planned for a later date.
Changelog:

* added Super Game Boy emulation (thanks to gambatte for the Game Boy core)
* extended hybrid scanline/cycle PPU renderer to support Mode7 register caching; fixes scanline flickering on NHL '94 title screen
* all windows (other than the main window) can be closed with the escape key now
* file dialog path selection now accepts typed paths; can be used to access hidden directories and network shares
* file dialog's game information panel can now be disabled
* fixed a crashing issue when the file dialog was given an invalid path
* fixed screenshot capture save location
* added screenshot capture option to tools menu
* state manager now auto-closes when loading a state; it can be reopened quickly with F3
* fixed GZip archive loading
* fixed NTSC off-by-one filter bug on hires screens
* extended Scale2x, LQ2x and HQ2x to properly filter hires screens
* added Pixellate2x filter

space invaders for game boy. if it's loaded onto a super gameboy you can play an embedded SNES version.

[Paratech]

Yes, sorry, I forgot to mention it was Space Invaders.

The "non" arcade version works, but trying the "arcade" version gets that error?

ah i think i know what the problem is. the bios is a PAL dump and the game needs an NTSC dump in order to work (the japanese SGB2 Doesnt work either)

[byuu]

The Japanese SGB2 BIOS works fine.

Use either Super Game Boy (UE) (V1.2) [!] or Super Game Boy 2 (J) (V1.16) [!] with Space Invaders (U) [S], and the arcade option works. I even took pictures of it running

Also make sure Settings->Configuration->Advanced sets the console to auto-detect or NTSC.

Oh yeah, don't forget to decompress your GB ROMs, I'll post a fixed snesreader later on.

[Experiment T]

hmmm strange i set it to PAL and it works fine yet if it's autodetect or NTSC it comes up with the error

[Paratech]

Yeah, that's what I had to do!

PAL? Why?

You must have a PAL copy of the SGB BIOS.

This emulator is excelent!

Is it possible to stretch the image to fill the whole screen? I get black bars up and down in all games so they look a bit squashed. Like if Mario ate a truck of Big Macs.

SNES video outputs at 4:3 aspect ratio, while your monitor is probably 16:9 or 16:10. You'll make everyone fat by filling the screen, but it can be done. Close bsnes, then go to start->run, and execute this:
notepad %APPDATA%\.bsnes\bsnes.cfg

Now look for video.ntscAspectRatio and change it to 1.40, eg:
video.ntscAspectRatio = 1.40

That'll work for the usual 16:10 monitors. One can play around to do the same for PAL and 16:9 monitors.

aah the great byu thanks for the work you do to bring us your brilliant emulator massive respect to you sir from da max

Thanks for the answer!
Well, actually my monitor is 4:3. But the black bars make the image a bit squashed, look:



My question was If I could remove that bars so I can fill the shole screen and get a nicer look.

Is this the only emulator that can emulate the Super Game Boy? Loved that on my PAL SNES.

Strange, the image is 640x512. 4:3 would be 640x480.

Essentially you want to control the video.ntscAspectRatio and video.palAspectRatio values. Lower it to make the output taller, raise it to make it wider. It should only take a few tries to get it just right. Don't forget that PAL will always have that black area in most games, only some PAL games draw there.

At this time, yes. Though I'm trying to help MESS and ZSNES add it, I don't know how long that'll be. ZSNES will probably be a really long time as they're in the middle of a core rewrite.

Super Game Boy emulator ?
There are also the GB/GBC emulators that emulate the Super Game Boy. For example, BGB emulate the GameBoy, GameBoy Color et Super GameBoy. But, it does not emulate fully the game Space Invaders.

With the new version of supergameboy 0.011, I can play Bomberman 2 in multi-player. But I can not play in multi-player with the normal GameBoy games, such as Tetris, or Hunt for Red October, etc. This is normal ?

Sorry for my poor english.

Thanks! I'll try that method. It worked for a widescreen image.
