I looked Meteoric Shower. It has no sound because the direct accesses to the SN76489 in ROM. I also noticed that you have not changed the OUT (0FFh),A by OUT (099h),A. So I do it and replaced the I/O to the SN76489.

Now the game seems work fine with sound on Franky, Musical Memory Mapper or Playsoniq. I added this game in the COL4MMM.zip.

That's a good thing to hear. Thanks for testing it and telling me.

Just tested Meteoric Shower on Mission, sound doesn't work on that too. Might as well use Franky, MMM, or Playsoniq to run the sound. Don't forget about Tank Wars and Strike It! All three of those are Bit Corp. games as I said.

Yes, sound works only with one of these cartridges. I just changed the I/O port number.

I also noticed that you have not changed the OUT (0FFh),A by a sound routine nor IN A,(0BFh) by IN A,(099h).

Hey, I'm just curious to know. A user named Perfect! on SMS Power! wanted to know if there would've been CV2SMS (mostly CV2SG) ports. They both use the Z80 just like the MSX. I once try to make a Mission emulator for the Master System (the 16kB version), but it wouldn't work. I needed to know if it would be possible to put the ColecoVision on the Master System, and also change mappers of the controller, like up is 1 and control up and down is 5 and control down. The pause button is going to pause the game.
