I am sorry to inform, that I dont make it to the deadline with my original plan, but it does not mean I dont have an entry. I will enter with a bit improved version of my tic-tac-toe. Just to Enter, I do not expect much, but at least that it what I have time for My original plan, is still in my mind, but It cant be ready before the deadline, but I will let you guys know later

I think the svi one is a.c. only I think 9 and 18 volts...

Something like this: http://www.eetools.com/downloads/catalog/EEROM-8U-2010.pdf

That is the same way I work, yes it takes time, plus I use a 512 eeprom, so i have to take the rom file and full the first 7fff of the rom, before programming the eeprom. What could be nice if there was an interface like a eprom, connected to usb, then this device could be pluged into the testcard. I think there is something called USB EPROM SIMULATOR but i guess is rare to find and very expencive.

Seems to be a lot of issues at the moments with homebrews.

you have a bug : ld a,(psgrd_wr) sould be in a,(psgrd_wr) I made that mistake too

I think I know what the trick is but not going to say anything. Not here not in PM no where

both inc (hl) and inc hl, is valid

a few years - cool and welcome back

if someone will pm the .rom file i will do the best to test it out....

somebody made a youtube video playing Knightmare at ColecoVision without any crash he completed stage 1 without any bugs ?

quite happy I did not port Knightmare, I remember some years ago, i was thinking about porting it But quickly saw its not going to work on a unexpanded ColecoVision and in that time, no one know about the SGM (we only know it from some Prototypes).

many games try to avoid flickering, by sorting the sprites, you can see it if you have a emulator can show sprites. There is a MSX emulator than can called "meisei" but none of the CV emulators I know can do that, I think MEKA should have, but I never see it works.

does anyone have the problems when running on a PAL ColecoVision. I think its a problem, that to game do to many cycles between the NMI Interrupts. A NTSC VDP have LESS time between interrupts than a PAL VDP has. So maybe the game will not CRASH at at PAL ColecoVision. Since more people report that the crash happends often when a lot of things are at screen? I had the same problem when porting a MSX game, it runs perfect at PAL ColecoVision but not at NTSC.

I have a lot of good idea's for the Coolcv emulator, like put in the best features from Meka, Mess and BlueMSX - debuger with breakpoints - realtime hexeditor for vram and main ram (including sgm ram) - A way to monitor if the code try to read or write in a specific area, ram and vram. - Dump registers, vram and ram to a file I know Oscar is very busy, but now he have some ideas.

Haha, I think most of us in here, with wifes/girlfriends knows that "Its just trash, make a game for iphone instead. bla bla bla...."

Hi. Have been busy with ColecoVision stuff (People in the CV world might know why).... I will do my best to come up with something, but 1½ month is not long time, but lets see

What I ment was is the same PCB type and rom chip used in other Pixelboy releases? since someone said he played other new releases with out any problem. Could anyone make it crash using Atarimax? If its a NMI issue emulators might work, but real hardware dont, I tried it many times, it runs YES, and then when you try on real HW it failed

Pixelboy, could it be something with the cartrigde PCB ?, you mention something about it can be programmed without remove the rom, are the other games people testet lately using the same pcb and rom. Most of our colecovision could have problems if the PCB of the cartrigde is a bit to thin? Could be bad connection in the cartrigde slot? I do not think the SGM module itself take to much power from the PSU, but could this be a issue too ?

actually I recall I have made the MSX version do something like that to, so maybe the bug is "original"

by the way could not catch a good picture of the "COLECOVISION" bootscreen, but at least 3 letters in the "COLECOVISION" was CYAN. Wonder if its a RAM problem, but not sure if the bootscreen use any memory at all...

Some pics....
