SG-1000 support on EverDrive-GG with OS v8
« on: January 17, 2015, 05:57 AM »
After an embarrassingly long delay, I've finally gotten an EverDrive-GG (in addition to my EDs for Genesis, SNES, and Game Boy).

However, I was dismayed to learn that SG-1000 palette support -- which was one of my main reasons for buying the EverDrive-GG, and which Krikzz added back in 2012 -- appears to have been disabled with OS v6. All the SG-1000 games I've tried are unplayable messes of black and purple.

What's the deal with that? Is there any workaround? And can I downgrade to OS v5 without any negative consequences?

I dont think there would be any consequences downgrading to os v5 but fat32 and sdhc cards dont work on the old os so keep that in mind. That and the newest update on the EDGG says os v8 and that aint available to download (unless v7-beta is v8) so you might want to downgrade permanently if you are downgrading at all. If going that route, put the os on the sd card and run it like any other rom. Idk why sg1000 support was dropped as well since the master everdrive can play them no problem and it used to work on old os's.

Thanks for that quick reply & information. I don't know why I had it in my head that I had OS v6, but I just checked and it's OS v8 (which makes sense since I just bought this from Stone Age Gamer last month). My mistake on that.

Since the downgrade would have to be permanent, maybe I should contact Krikzz directly and ask whether it'd be possible to restore the SG-1000 palette setup first?

EDIT: I've emailed Krikzz at the tech support address.

Thanks, glad to know others care about this. :) So far, no response from Krikzz.

Er, KRIKzz, didn't you implement SG-1000 support a while ago?

(Linking to Google Cache since AssemblerGames seems to be down; see posts #199 and #200 at the bottom of the page. Or I'll just post the quote: "in lastest os i implemented palette init for sg1000, now sg1000 games works fine on gg")

The changelog for OS v5 even mentions it:

"v5
14.12.2011
1)palette initialisation for sg1000 games (gamegear)"

So it certainly looks like it used to be in there! Any idea why it disappeared between OS v5 and v8?

I don't remember, to be honest. I completely forget details about work over sms/gg due the time and low intensity of work over this project. It was so many time ago...

So it certainly looks like it used to be in there! Any idea why it disappeared between OS v5 and v8?
May be because i did not make palette initialization for game gear. OS7-8 were made from zero, so, may be i lose something.

I understand, KRIKzz -- you've got a lot of projects to worry about, and the SMS/Game Gear is one of the least active. Still, if there's any chance you could restore palette initialization in OS v9, that'd be great and really appreciated.

The SMS doesn't need it -- AFAIK, the colors are hardcoded by the SMS VDP and can't be changed, and the games are at least playable. So it only applies to the Game Gear, where SG-1000 games are literally unplayable since you can't see anything.

Do you need a color chart or anything? There's a page by Chris Covell about what he did to set up the SG-1000 palette for the Tototek flash cart.

KRIKzz, just chiming in as another GG Everdrive lover that would greatly appreciate some SG-1000 support!  I rave about this flashcart and have another friend that is interested in buying one soon.  Honestly, I don't know why GG gets so little love.  And this flashcart has been a dream to have in my collection :D

Also, if you get around to it in the next OS (I know you are really busy), here is a list of some games that don't seem to work yet on OS7:

Gunstar Heroes (GG)
Rastan Saga (GG)
Predator 2 (GG)
Chase HQ (GG)
Megumi Rescue (bad dump, player doesn't control correctly)
Outrun Europa (GG)

There appears to be an issue with some SMS>GG conversions that were done for the GG.  Also, without a proper PAL hack games like New Zealand Story and others have graphics glitches.

Thanks for your hard work and a great product!

I'm curious to know if SG-1000 support has been restored?

My guess is that it won't be fixed on the current everdrive.  I'm thinking if he releases a new version of it he'll write new a OS for it.  With maybe fixes for all current issues.  I can't speak for krikzz but I can only hope.  I love the ed for gg but I would rather have a better version of it someday.

KRIKzz, could we see some movement on this? Those of us who bought the cart would love to finally have SG-1000 compatibility restored.
