Hello Guys and Happy newyear every one, and thanks for the support - especially to the crew of Collectorvision.com and the people who bought my 3 games released in 2013. I can promis there will be more games in 2014

Depends, No one wrote a price on it, so you can tell them the price was 8 euro or so. I think in Denmark. if its less than 50euro, no taxes but you pay vat, also on the shipping costs But didn EU made a trade-agreement with Canada,so maybe in the future? - or maybe its only Business to Business?

I dont think its an error. When the programmer set up the vdp or so, it will print this to the screen, but you will not see it on a real colecovision cause maybe is just in one frame. Ofcause the you can catch those kind of things in a youtube movie, I think if you browse other games frame by frame you will see things you will not notice at a real ColecoVision, when you play them

Amazing, I though the ColecoVision was a direct MSX port, but it seems like it was converted to C. That make it possible to reach more platforms

Yes I let Collectorvision do that part, but in the build-in-game-instructions, it will tell you, but you may not remember so overlay is better

Hi;) Super Minefield pass final tests, and should be ready, I have no plans to change anything in the ROM at this point of time. Memotech MTX Games Collection Vol 2 (Codename "The Keys" cause it have 3 games programmed by A.KEY) - The games in this collection will be: Nemo, Star Command and Obloids I estimate 1-2 weeks to finish this ROM. Star Command could use overlays - could be handy cause almost all keys at the keypad will have a function also

i quickly checked pin1 on both ic's u18 and u19, both have +5v, do more checks tonight:)

I think its something wrong on the way to U19, it returns the same bit pattern if the U19 IC is removed!

The problem was/is not the IC's I put in sockets today with fresh IC's. I am not sure why but port 0xFF is working 100% but port 0xFC have returns the same bitpattern. actually bit 0 and 1 is "0" and the rest is "1" it should be impossible cause bit 7 should always be "0" as I know. After a test I swap around IC18 and 19 same result. So it could not be a bad IC. Any more suggestions?

Guys Denmark is a small country :) :) By the way got mine two days ago - of cause that was my "own personal copy of my game" so maybe it does not count? mine came in a box used for car break pads

HI I Finally removed U18 and U19, now waiting for sockets and replacement IC's. Those IC's sometimes fail, and make controllers not work or keypad on controllers not work. For mine it was bit0 and port fc. It seems like when those ic's was soldered to the main board, the pins was bend and then soldered. So when you want to remove the ic's add new solder to the pins, and then make sure it mix with the original solder. then use a small flat screwdriver and the solder iron to bent the pins up from the mainboard. After this use a desolder-pump to remove the solder, add new solder if needed, and try again.

yes a noticed that, Mine is a NTSC USA version. By the way tried to send PM to you 5-11under, but it keep says "message have to be 3 chars or longer......"

I found this tread: http://atariage.com/forums/topic/140062-colecovision-problem/ Its U18 or U19, maybe replace both if I can find them, its should not be so hard since the console is not assembled, currently always open But not sure if I can find the ic's localy or need to order from ebay thanks anyway -and yes I did try without any joysticks connected and diffirent joysticks too....

IC U18 and U19 are equal, maybe they are the ones controlling the joystick inputs? Its SN74LS541N

By the way it seems like bit 0 at joystick port FC is always "0" so the cv thinks the joystick is always pressed "UP" and keypad 6 is always pressed. Port FF seems to be normal.

Hi. Suddenly discovered that my USA CV Console, start games itself, and it seems like the Joystick UP is always pressed. If I press keypad 1 it read it as keypad 2. I remember i read some where its some chip, that is bad, but which one? Any clues?

Not to be a annoying, but did you get the rights from Eurosoft to use the Graphics ? I was planning to convert a few eurosoft tittles to Memotech MTX, and it seems like the guy who hold the rights are still in business. I dont remember his name but he is active at the MSX.ORG forum as i know.

And I can ensure you guys, its not the last "homebrew" comming from here I plan to release at leat 2-3 more Memotech Releated Games. And maybe one MSX conversion;) hopefully this year....

I have used MSX-O-MIZER, for compressing my ported games for Memotech MTX, its quite good. But to use it on ColecoVision, you have to think a about Memory, cause it will use around 340 bytes of RAM, to decompress. So If game is using to much Memory, that use DATA which can not be cleared out it could be a problem.Using MSX-O-MIZER at the including files, compress to 3337bytes. Ofcause MSX-O-MIZER is based on Exomizer v2, so no wonder. but when you write a game from scratch it should not be a problem, could move importend data from ram to vram (to a safe location, where compressed data dont overwrite), and then transfer it back afterwards.

Hehe dares to.. But there are a good chance it will be finished within those two weeks
