christo930 Posted September 29, 2021 Share Posted September 29, 2021 Is the expansion module number 2 (IIRC) 2600 thing supposed to work with the Harmony cart for the melody board games? I could get regular ROMs to work with it, but none of the melody board games like Scramble or Space Rocks work with it. I tried running them as part of troubleshooting having problems with some melody board games not working on some (by will on others) 2600s I have. While I found some that work on one machine but not another, I found that none would work on the Colecovision 2600 expansion module. Quote Link to comment Share on other sites More sharing options...
Prizrak Posted September 29, 2021 Share Posted September 29, 2021 I don't own one but from what I've seen on here the Harmony should work as well as all the games that will run on the cart. The expansion module is a 2600 made to use the main systems power and video to display your games.Sent from my SM-G996U using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
+SpiceWare Posted September 29, 2021 Share Posted September 29, 2021 Should work. @Omegamatrix does report there can be issues if the Coleco's expansion port doesn't make a good connection to the expansion module, so you may need to clean it. 1 Quote Link to comment Share on other sites More sharing options...
