digress Posted October 25, 2022 Share Posted October 25, 2022 Master system is the Colecovision 2. 1 Quote Link to comment Share on other sites More sharing options...
fiddlepaddle Posted October 25, 2022 Share Posted October 25, 2022 As a Colecovision fan, this is very interesting to me, but I know nothing about the SG1000. Does this mean one could potentially play Colecovision games on a Game Gear, since you can play Master System games on one? (Also, my browser, which is unfortunately older and can't be updated without upgrading my OS, doesn't show anything but a blank space between "...hence slightly off colours): " and "To access the keypad maintain the PAUSE...", so I'm probably missing some key information here...is this a hardware or software adapter?)

Yes you could play CV games on the GG, only you woud need to add a small piece of code to initialise CRAM to the closest CV colours (not needed on the MS as colours in compatibility mode are fixed/hardcoded). There's a video of it running and a drawing showing the keypad mapping. 22 hours ago, eebuckeye said: Want!! Will you offer for sale? Probably not, there's not much interest for it. It was mostly a fun exercise for me after I saw people were converting games manually (patching the code). To make it a commercial product it would need to have hard gold finish on the contacts and a beveled edge, which jack up the price a lot for small batches (<=10 units). Making it open source won't satisfy the few people interested neither as it involves SMT soldering and CPLD programming (either with a programmer or a JTAG cable). On top of that I don't have the time to write documentation and support it. Quote Link to comment Share on other sites More sharing options...
imstarryeyed Posted October 27, 2022 Share Posted October 27, 2022 I would totally want one of these! I love strange but cool hardware addons especially for the Sega Master system! Cool Project! If you happen to make a few let me know as I will buy one from you for sure! Quote Link to comment Share on other sites More sharing options...
+eebuckeye Posted October 27, 2022 Share Posted October 27, 2022 The concept of this is very cool! I wonder if there is any chance it would work with the Master System adapter for the Genesis? Playing Coleco games on the Genesis would be wild! Regardless I would really like one if you decide to build! Quote Link to comment Share on other sites More sharing options...
K-Rod 13 Posted October 27, 2022 Share Posted October 27, 2022 Definitely interested in buying one also if you do make more. Quote Link to comment Share on other sites More sharing options...
fiddlepaddle Posted October 27, 2022 Share Posted October 27, 2022 So, after referencing this article (https://hackaday.com/2008/12/11/how-to-programmable-logic-devices-cpld/), it appears one could use a CPLD inside an a SD card multicart (similar to the Atarimax Ultimate SD I have) containing some special boot-up code for the colors, could allow a person to potentially play Colecovision games, Master System games, SG-1000 games (and maybe some Game Gear games) on a Genesis? If that was true, I bet the market for a device like this is much bigger than you think. Quote Link to comment Share on other sites More sharing options...
SiLic0ne t0aD Posted October 27, 2022 Share Posted October 27, 2022 (edited) Very cool! Open sourcing it would be welcomed I'm sure.. There's more people interested and capable of building it than you'd think. Hope you'll consider it. 🙏 Edited October 27, 2022 by SiLic0ne t0aD Quote Link to comment Share on other sites More sharing options...

The adapter can already do that, I've tested it to play SG-1000 games on the Game Gear (picking colours that are much closer to the CV ones than those hardcoded in the MS VDP). Master System games on the Megadrive have always been a thing through the Power Base Converter. 1 Quote Link to comment Share on other sites More sharing options...

Master System games on the Megadrive have always been a thing through the Power Base Converter. This was my first thought, since the Genesis sold more units. Thanks for touching on this. Are you saying that it would not work, because CV would be considered a legacy mode (like SG-1000). I find this intriguing. This didn't quote the part about the muti carts. I have an Everdrive. It would be cool if it supported CV games too. I guess it would get messy, because keypad support would also be something that may need addressed, such as your on-screen solution. When I created RatTrap for the 7800, I revisited the ColecoVision version of MouseTrap. I find that playing the game on some touch-screen emulators is nearly impossible, since all buttons are on-screen. I supposed it would be similarly challenging if an on-screen keypad needed to be brought up. Overall, I think this is a really cool project. I saw it today in a Facebook feed, and I had to hunt it down on AA. Nice! 1 Quote Link to comment Share on other sites More sharing options...

Both the SG-1000 and ColecoVision use similar VDPs (9918 for the SG1K, 9928 for the CV) whose graphic modes were not included in the Genesis/Mega Drive VDP. Technically they do work, but you'd be playing them blind because the Genesis/MD would just display a black screen for those games. Quote Link to comment Share on other sites More sharing options...

It's not an on-screen keypad: you need to maintain the PAUSE button on the console then press a direction/button combination as explained in the picture posted in the first post. That's far from ideal I know, you need to sit close to the console. But many games use only one or two buttons (all the arcade ports, etc.). 2 hours ago, evg2000 said: I wonder if a developer like @Digital Fluff might be able to produce it for them?

No because the Megadrive/Genesis VDP doesn't support legacy video modes. Quote Link to comment Share on other sites More sharing options...
