Justin Posted September 20 Report Share Posted September 20 The “ColeCoco Master” is a new pass through cartridge for the Sega Master System that allows you to play ColecoVision games on your Master System. It’s $69 and works on standard, real hardware Sega Master Systems with original games. It seems to have an issue with a very bright color palette compared to what the ColecoVision had.

OniDensetsu Posted September 20 Report Share Posted September 20 Thats neat but not $69 neat being all wrong colors & all. LOL $69 Dudes! Sorry to be a negative Nancy yall but its who i am & i look at it as being honest 😀 DegasElite and Justin 2 Quote Link to comment Share on other sites More sharing options...
DegasElite Posted September 20 Report Share Posted September 20 I can understand how it works. Both systems are close cousins. They use the Zilog Z80 CPU, and they are both cousins to the SG-1000 as well, which I believe the ColecoVision is based on. Well, it isn't perfect, but it is an achievement. Nice!

RickR Posted September 20 Report Share Posted September 20 This means they can make something similar for Genesis, right? Pretty cool IMO. DegasElite and Justin 2 Quote Link to comment Share on other sites More sharing options...
DegasElite Posted September 20 Report Share Posted September 20 Well, I guess the Genesis Everdrive can play SMS games, which I heard about on this forum. It needs some kind of software loaded onto the Everdrive, I believe. Then, you would have a virtual Power Base Converter. I don't remember who posted it, though.

DegasElite Posted September 20 Report Share Posted September 20 It could also depend on the model of the Everdrive as well. Justin 1 Quote Link to comment Share on other sites More sharing options...
RickR Posted September 20 Report Share Posted September 20 I think that was me, and my everdrive does SMS games with nothing extra needed. But since the Genesis is 100% compatible with SMS, it seems it would be easy to create a Colecovision cart for Genesis too.

DegasElite Posted September 20 Report Share Posted September 20 That could be. I don't know if special software would be needed, but it is entirely possible. Of that, I am sure. Justin 1 Quote Link to comment Share on other sites More sharing options...
Justin Posted September 20 Author Report Share Posted September 20 I would be 100x more excited about this if they could work out the kinks. DegasElite, OniDensetsu and MaximumRD 3 Quote Link to comment Share on other sites More sharing options...
CrossBow Posted September 21 Report Share Posted September 21 (edited) Okay... so I do own one of these and John didn't research this one as well as he should have. So let me point out a few more technical parts to help explain things. The SMS has a VDP in it of nearly the same architecture as the the one in the CV however, Sega did NOT replicate the palette exactly in the VDP hardware on the SMS. As a result, what we are seeing with this adapter is the nearest match of the values programmed by the CV game and how it comes out on the SMS VDP. There isn't any software of hardware fix for this. It isn't something that can be compensated for because it is the way the hardware is inside the SMS itself. This works by flipping on the SMS's internal SG-1000 compatibility mode. Strange enough, even in that mode to be compatible with SG-1000 games, the colors aren't correct there either but Sega apparently didn't care and figured it was good enough. This adapter can't work in the Genesis or the GG with a master gear converter because both consoles do NOT have the SG-1000 compatible video modes programmed into them and were essentially made to be SMS only compatible. Some of the needed pins from the cartridge port on the Genesis aren't present either that would be needed for this to work. That is what was explained by the devs of this adapter. That all said, I still find this to be a very impressive piece of hardware as it does basically play all of the original released CV games although with the altered colors in places. I provided direct captures from several games in the AA thread where this was all discussed to provide a better comparison with some of the games on an actual CV vs what is shown on the SMS through this adapter. I will also state that the devs have stated they didn't make this with the homebrew games in mind. So the fact that many homebrews don't work right isn't that surprising. It might be something they can improve on, but as I understand it, this cartridge adapter is NOT FW upgradable without sending the carts back to be FW upgraded. One interesting thing I did notice about playing games on this vs an actual CV. They play a little smoother through this adapter. Cosmic Avenger stood out because on my actual CV it scrolls with a bit of a studder at all times. This was NOT present on the adapter and it was very much smooth scrolling. The cartridge adapter does have its own internal z80 inside it but I'm not sure what function it plays. The adapter PCB is pretty well packed with several large ICs inside it. I also seem to have a slightly better experience with mine and my hardware vs some of the others. As an example, my AtariMax has the same menu issues that John pointed out in his video and the BBPro is even worse. But, oddly enough I can load up games on my BBpro from a specific part of my roms and when I reset the BBPro, the menu suddenly shows up full and properly so I can easily navigate and select games? But it will revert back to being a graphical mess if I reset from that game to choose something else. NO idea why some games that I load up from a specific part of my cart will cause the menu to work while most don't but no one else with a BBPro has managed to replicate this with theirs and just have scrambled looking menu screens all the time. I also seem to have less games with graphical glitching as compared to some. I think the hardware has a lot to do with it as I have what I think is the first US release version of the SMS model 1. It only has the built in snail maze game and uses the leaf switches for the pause and reset. I think is it US BIOS 1.3? But with all the mods I've got in mine, I was more surprised at how well it actually does work.

DegasElite Posted September 21 Report Share Posted September 21 But, whatever the case may be, this adapter is (to me, anyway) phenomenal. I hope it can be improved for better performance. But, already I like it. Quote Link to comment Share on other sites More sharing options...
