Have any of you guys done a port from MSX to Coleco yet? Assuming the game only uses 1k RAM (or can be modified to only use 1k), what are the hurdles? I was looking at the MSX and it appears to have a ton of built in bios routines like the Coleco, so I assume getting around those is the first major problem. Any specific advice for someone who is dabbling in it?

Dvik/Joyrex has done some, Opcode too
They've alot of knowledge with MSX to ColecoVision port

You should really ask them

Here is a Coleco to TI-99/4A conversion of Tutankham (yeah, I know, not MSX but still the same Texas Instruments chip technology here and there) by retroclouds:



I'd love to see other ColecoVision/ADAM games receive TI-99/4A ports, such as:
*Donkey Kong (cartridge version; 16K ROM chipset)
*Donkey Kong Super Game (ADAM)
*Donkey Kong Junior (cartridge version)
*Donkey Kong Junior Super Game (ADAM)
*Smurf Rescue in Gargamel's Castle Super Game (Super Game Module)
*Super Cobra

If I had MSX-to-ColecoVision conversions on my mind, it would be these following Konami games:
*Hyper Rally
*Pippols
*Track & Field
*Vampire Killer
*Exerion

I've a couples of screenshots of this unreleased Super Smurf
I'm planning to recreate it someday...

This would have been a great game from what I've seen

I'd love to see "Malaika: Prehistoric Quest" ported from MSX1 to the Colecovision (and to the TI-99/4A as well).
That is a fine homebrew game indeed.

Don't know if it would be possible on the colecovision with 1K of RAM though.
Check the screenshots here.

First time I heard of this game
Looks like a fun game, I'll give a check tonight  

Thanks

looking at the screenshot, it seems it is more a MSX 2 game notMSX 1.

It looks like something the 7800 could do too. I already have a long list of projects so I won't be doing it.

Yes, it does look like a MSX2 game, but it is an MSX1 game.
It won 2nd place in the MSXdev'06 competition. That's a competition for development of new MSX1 games.
Check here.

It does have very smooth scroll, which we all know is very hard to do on the TMS9918.

MSX to Coleco....

I really hope there could be Coleco to MSX ports too!! (and not just in my dreams.....)  

There are many original 1980s games, homebrew games and "coming soon" games and "maybe" games which I would gladly buy for my MSX-1.

If just someone kind soul could port them.... .....there surely are many MSX cartridge makers who are willing to make them to a cartridge form!!

I wish to have opcode´s Donkey Kong arcade + All Coleco´s Donkey Kong conversions (including Adam one) on same cartridge!

.....and Wizard of Wor.... and many others....!



Colecofan1981, Vampire Killer is MSX2 megacartridge game, by the way....

Now that I've translated my games from MSX to Colecovision (Zombie Near and Princess Quest), I can tell you that the most difficult thing (apart from direct hardware access) is the NMI interrupt from VDP (INT in MSX), as it cannot be easily deactivated, some clever programming solves that.
And now I'm limiting every game programmed to 1K of RAM, that simplifies a lot of things if I want to do a port to Colecovision in future.

There exist a great remake of Vampire Killer for MSX1, it is called The Cure and it is available from MSXdev archives.
