Good news! Spy Hunter seems work fine with the JoySNES and is also playable with the keyboard. I will release it soon, after to make the franky version and little doc.

Done! Spy Hunter is added.

Download: COL4MMM.zip

I made two versions to play in the 2 players mode with one or two JoySNES. Both versions are playable with the keyboard.

I added Bump 'N' Jump. This one wasn't easy to convert and there are a few little slowdowns like Galaxian that I couldn't get rid of.

I saw the NES version that is very nice. It would be nice to have a version for MSX2 that rivals.

Edit: If you replace 3E 80 DD 21 80 01 by 3E 81 DD 21 80 01 the game will run in R800 mode on MSX Turbo R. So the game becomes too fast but remain playable. You can try it for the fun. Running Naked in a Field of Flowers

Stern's Frenzy is updated. I modified the control and interrupt routines. Now the player 2 can play with the keyboard.

I noticed a strange thing in this games. RETN is at 8020h instead of 8021h. I tried to check if the interruptions were permanently disabled with BlueMSX but the debugger doesn't seem to properly show the contents of the vdp register 1 when the Coleco is emulated. It calls 0066h only from the moment a player dies without register 1 changing. So I couldn't tell if it's normal or not.

I tested BC's Quest For Tires 1/2 and them don't work fine.

BC's Quest For Tires sometimes has small graphical glitches on real MSXs.
BC's Quest For Tires II has small graphical glitches and bugs a lot on real MSX1.

So I looked at the programs and corrected both.
There are 3 versions of BC's Quest For Tires II available online. One "Bad dump", a 24k and a 32k.
Taylors used the 24k version. This version is bugged or this is a bad dump.
The 32k version is in fact a 24k version. It seems work fine. I can play it on MSX without any issue. I'll test a little more and I'll release them.

Several coleco ROMs were badly dumped. There is no longer anyone to make proper dumps for a long time.
