Ironically the Creativision MK-II was designed to do this with a CV expansion cart, that was never released. All of those systems used the same VDP, so obviously that's the connection, and what makes it possible. But you know, sometimes there's a difference in the palette, or the controls stink, etc. the Colecovision Module for the Creativision has been somewhat released. In fact the module exists for the VTech computer Laser 2001 which is no more less than a Creativision with a Keyboard and a little more Ram. Most of the Creativision Game are i think compatible with the Laser 2001. Quote Link to comment Share on other sites More sharing options...
Ikrananka Posted September 23 Share Posted September 23 I've finally found some time to spend with my Coleco Chameleon Cartridge. Others have already gone into compatibility with ColecoVision and SGM games, so I decided to take a deep dive into the CreatiVision mode. A fantastic source for CreatiVision roms can be found here : https://www.madrigaldesign.it/creativemu/roms.php I've been through all of the original games and the homebrew games, excluding demos and utilities. There are quite a lot of issues with running homebrew games, but to be fair, most (but not all) of the original games for the system work great. I'll list the problematic games below: Original Games Auto Chase - screen tearing when the scenery scrolls and a few other graphical glitches Deep Sea Adventure - screen tearing of the tops of the underwater mountains when the scenery scrolls Planet Defender - screen tearing of the tops of the mountains when the scenery scrolls Homebrew Games None of the cross-compiled games by Inufuto work. Deep Sea Adventure (fixed by Michael Obsieger) - just gives a screen with garbled graphics MazezaM - displays a solid cyan screen Tile Breaker / Breakthrough - requires the player to select 1 or 2 on the CreatiVision keypad which isn't possible as these have not been mapped to the ColecoVision keypad. Whack'em Smash'em Byrons - just gives a blank blue screen. 1 Quote Link to comment Share on other sites More sharing options...
Ikrananka Posted September 23 Share Posted September 23 (edited) I'm also confused as to the sorting order when browsing games on the Chameleon. It isn't alphabetical !!! Date file created or modified perhaps? Edited September 23 by Ikrananka Quote Link to comment Share on other sites More sharing options...

I think it's by file written order. IIRC I had to use a utility like this to sort things out alphabetically: https://sourceforge.net/projects/fatsort/ Quote Link to comment Share on other sites More sharing options...

Also, yes just validated that you need something ike FATSORT to sort the directory in alphabetical order. 1 Quote Link to comment Share on other sites More sharing options...

IIRC I had to use a utility like this to sort things out alphabetically: https://sourceforge.net/projects/fatsort/ Ah - thank you. I did try changing the three date parameters of my files (created, modified & accessed) and that makes no difference. Yes, I see now that it's the order that they're added to the SD card (as you said) and that's something that fatsort deals with. I just brute forced it by deleting all my CreatiVision files from SD card and then copying them all back in one go. As Windows copies them back alphabetically this sorted the order shown on the Chameleon. Edited September 23 by Ikrananka Quote Link to comment Share on other sites More sharing options...

Right. I only knew to do this bc one or two of the other flashcarts worked the same way also. When I see this behavior fatsort usually gets things working. I didn't try all the games you linked but did see that Auto Chase and Planet Defender worked the way you described. Do you know if there are more "new" home-brews being made and where those folks congregate? Quote Link to comment Share on other sites More sharing options...

But there is a forum link from the CreatiVemu website which has a development section: https://www.madrigaldesign.it/forum/viewforum.php?f=20&sid=c6a127c93d4df61209fac571618e6f9f Quote Link to comment Share on other sites More sharing options...

Whack'em Smash'em Byrons - just gives a blank blue screen. A few additions to the above incompatible game list: Original Games Deep Sea Adventure (6K) - garbled graphics, but the 8K version does work. Deep Sea Adventure (fixed by M Obsieger) - as this is a fix for the 6K version of the game this fix also doesn't work and gives garbled graphics Music Maker - while this runs okay, it requires the use of a lot of the CreatiVision controller keypad buttons. However, only two of these have been mapped to the ColecoVision keypad and so it is not possible to create any music. Tank Attack (6K) - white screen, but the 8K version does work. One caveat is that it is not possible to "lay mines" or "switch tank" as these use CreatiVision keypad buttons that have not been mapped to the ColecoVision controller keypad. Homebrew Games Cross Shoot (32K) - but Cross Shoot Lite (16K) works. Could be that the emulator in the cart is limited to games up to 16K in size.
