i think there is no BIOS on the SG1000 and there is one for the Colecovision. MSX has a different sound chip and a different Bios. Spectrum has not at all the same vdp , it works differently (main memory is used as screen buffer, colecovision vdp has its own specific memory) despite resolution and color constraint are similar to one of the colecovision graphic mode. But the spectrum has no hardware sprite.

Generally i try to avoid situation where more than 4 sprites be in a row , but one little trick i use sometimes , is the case you have sprites that are compounded of 2 superposed sprites (to have 2 colors sprite) , i play on sprite priority of each layer. It means a sprite never disappear completely . when you have multiple colored sprites , you have to take care that you have always one of the layer of each colored sprites having the first priorities.

i do not know that BASIC , did not have the time to test yet.... but i would expect that PRINT AT would have 3 parameters, like PRINT AT X,Y,"TEXT" . Did you not just forget to put the Y value in your statement?

😮 Even better than KnightMare!!! 😍😃

@nanochess : Just an idea , but i guess you have already think about it , it would be great when your basic is done for coleco , that your compiler be able to generate binary for SG1000 and why not also MSX , Spectravideo SV318 , MTX ...

I imagine it will have a kind of compatibility/similarity in the syntax with the intyBasic? That could easy some port from existing Intellivision game done in Basic.

impressive!

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.

Unfortunately i have lost it when i sold my C64 in 1986 with all my disks to buy an Atari 520 STF. i would have love to find it again. The only thing i have found from my childhood with the C64 thanks to the internet is a drawing i did when i was 10 years old for a drawing competition on C64 for "on Floppy disk" magasine published in France named "Floopy 64". And i had won the 3rd Price!!! (it was a box of 10 floppy disks) Don't laugh , i were only 10 years old 😀 and it is done using the joystick and Paint Magic (The “magic” in Paint Magic « My Commodore 64) This is the picture.... http://www.atomicfe.com/archeogamers/upload/floppy.jpg

Very nice Game! When i was 11 years old , i did a Pacman clone on my C64... there was only one ghost! But i was a real ghost he could cross the walls! 😀 But was my first "full" "real" game , before that it was just various experiment and few utility program. My Pacman was by far not as good than your Viboritas!😀

Why do you want use mode 0 ?

Peut être que l'on s'y verra à nouveau à la RGA , j'y ferais peut être a nouveau un tour cette année si je peux.🙂

I got the same screen in a room of exploration 4. BTW fun game , thanks Nico!

i think Atari Max somewhat cleans the memory before starting a game. May be game expect a clean to have a clean memory before starting , and no code cleaning that memory being present in the game itself. It would mean than as the memory could be in a random state when you start the machine it could cause problem. But honestly i would be very surprised if there is no code in the game itself to clean thing at start. Mystery Man knows what he does.

Could it be a problem like the PCB is consuming more power than other one? And so old PSU could have difficulty to provide the needs? My cartridge works well , but i tested it on a modern hardware.

Color on the screen of your first copy seems strange , no?

looks very nice!

Don't have issue with that. For me the colecovision controller is one of the best... but it was my first console , so it is like i'm born with that controller in hand!

When i try to install the last version on my machine , i got an error during the installation process : When i click Ok , i got then the same popup but with Error code 2502 . Do you have an idea of what could be the cause? Thanks

Is There already some gameplay coded? Or just what we see on the video?

It does not work on a colecovision with a F18a? but it works on the Phoenix? strange. I finally be able to test it!... a friend send me his copy to test. Very good version , but on a colecovision 50hz it flickers as the hell. Anyway , i find in the goal to do a port as close as possible than the arcade version on a Colecovision, you can not do better! Amazing work. Love it. 😍

Thanks a lot! 😍

It is my feeling also. Very nice work.

This version is impressive. I love the graphics. I guess it uses a 128k cartridge? I read in a comment on the video , it is based on a port of the MSX 2 version? Is it true? Mystery Man did again a incredible job!😍 If somebody has this game and does not like it and want to sell it , please contact me.🙂

I prefer the C64 version because nothing is better than a C64!!!! Your version is very nice, very clear , but the mountains on the top are missing .
