Super Game Boy SNES core with MSU

[mathieulh]

I compiled the MiSTer binaries and the SGB core so that they contain the latest commits from the MiSTer Main and the SNES (mostly SPC related fixes) core. I thought I'd just share these here.

[mathieulh]

Did anyone actually get MSU working on here?

Tried the same exact files that were working on the SD2SNES Pro and nothing is working.

The regular Game Boy stuff works fine, but the MSU versions don't work at all.

Even changed the MiSTer main as instructed

I only managed to get Link's Awakening DX to work for some reason, anything else I've tried doesn't seem to work on MiSTer (and probably real hardware), I assume whatever patches they've made for other games were only tested on software emulators.

Why wasn't this posted on this MiSTer Github?

My guess is that it will be soon, it just hasn't been decided yet how it will be handled, as it is basically a "secondary" SNES core. Need to make sure that all the beneficial commits to the SNES core also make it into the SGB core.

Considering that both GB and GBA 2 Player have their own sections, I don't see why SGB couldn't have it's own.

Amazing work paul! Personally, I prefer to use the Game Boy core bc of savestates. Regardless, this is still really cool!

Btw, is it possible to port the code of the special audio to the existing Game Boy core? I don't care as much about the borders personally, but the SGB audio is the only thing that I feel is missing from the standard Game Boy core. Can that code be ported over, or is it too dependent on SNES hardware to fit into the Game Boy core?

"the code of the special audio" is the entire SNES more or less.

I like those few GB games who use the actual music from the Snes version of the same games.

I just rebuild the latest MiSTer Main commits (including the new video changes) along with SGB MSU Support, I thought I'd share. (the SGB core's rbf itself remains unchanged)

Thank you for sharing

Tetris Flash[JP] does not start or does not show up on the screen

[MorkMikael]

bad dump probably. works on sgb 20220608 for me

[Ko2]

The Tetris Flash ROM matches the registered checksum and works fine with the GB core. But if it works, then it may be just me.

[MorkMikael]

what checksum are you are you referring to there is alot of different sources.what resources are you using as reference for the checksum.also there is a bug that i think happens on sg2 to on real hardware.you can also try using SGB speed: snes or sg1 mode and the bug disappear.i think early relesses of it my not work with the super game boy 1 or 2 the game is complicated.its the same with tetris 2.

This is awesome. Everything seems to work fine for me. Donkey Kong plays perfectly and has the extra sound channels for Daisy's voice.

[MiSTerDolch]

It's probably something I'm doing, but when I use the Super Game Boy Player I can select the SGB bios, then when I go to select the .GB ROM, I only see any ROMS that are on the SD card, not the external USB drive I use. Took me a while becaues I only have one .GB ROM on my SD Card for testing. I can see the Game boy Roms just fine with the Game boy Core on the USB drive, just not the Super Game Boy Player. If I FTP in and move a ROM from the USB drive (0) to the SD Card I can then see, select and play the game just fine. What am I missing?

Is there an empty games folder on the SD card you need to to remove so it'll look at the external drive instead? I don't use an external USB drive, but I think I've had that issue with SMB shares.

My experience with the PSX core has been that you need the Games folder, and the system's folder inside it just like on the SD Card. Someone correct me if I'm wrong.

under hardware in the menu there is an option to load a .bin boot rom. what is this?

Sorry I was not clear on my last comment
On hardware, I use Super Game Boy 2 SGB2-CPU (Japan) (Enhancement Chip).bin (it is a bin file)
On Load SGB Bios, I use Super Game Boy 2 (Japan).sfc

[JayRockets]

but do you know what it's for? everything works so far without loading a .bin

[TLPD-AVW]

It's a Game Boy bootrom (also traditionally mistakenly called "BIOS") stored inside the Super Game Boy cartridge, similar to bootroms you can load in the Game Boy core. The .sfc file is the SNES part of the SGB rom, .bin file is the Game Boy part of the SGB rom.
