Re: [help][creativision][cc65]CROSS CHASE: a universal 8 bit game/framework

Hi Fabrizio,

I am no expert at all, but maybe it has to do with the memory layout of the Creativision ROM1 / ROM2 Banks...
I have attached a memorymap layout for you...

Re: How to build a creatiVision power supply

Hi, I opened up my Creativision MKII (i guess yours is an MKII) an i found, that the internal PSU part is different to an MKI (and so different to the schematic one finds online...) Using a 3 Wire Transformer (with centertapping) will NOT WORK with a Creativision MKII (not sure about the MKI, as i d...

Re: How to build a creatiVision power supply

Oh Noooo! Maybe there is a fault (short) on the console, that caused the PSU to fail in the first place? Please make o picture of how you connected the transformer to the 5pin Din socket Frying diodes takes a lot of current / voltage surely... Dumb question: you did use the multimeter in AC mode to ...

Re: How to build a creatiVision power supply

Hi, Looking at the CV circuit diagram i think a transfomer with multiple taps (18V and 9V centertapped) like the one mark-emark uses should work! both voltages go directly to their own set of rectifying diodes so there should be no "interference" between them. (The Ti-99 4a also uses only 3 wires to...

Re: How to build a creatiVision power supply

Hi mark-emark, Maybe your PSU is working, but the Plug was the problem? Have you opend the 5pin DIN Plug? I guess there are broken solderjoints in the Plug (the red wire should definitely go somwhere ;0) (to the free pin)) and there may be a short between blue and green? Do you have a multimeter? th...

Re: Hello, Australia again - Adelaide

Hi Mark and welcome to the forum! The Creativision PSU is "dying" rather often... (some short in the windings or a burned "heatfuse") i repaired /rewound one once, but it was a pain in the a.. ;0) There seems to be no (cheap) replacement PSU for the Creativision... But it is rather easy to build one...

Re: Creativsion support added to cc65

Hi again, I would love to see the cc65 for the Creativision grow into an even easier toolset for the CV (Easy Graphic libraries, Sprite libraries, Sound, maybe even Scrolling?) So that it would be "easy" to program (small) games in C without the need of Assembly Code (i can´t come to grips with asse...

Re: Creativsion support added to cc65

Hi,

I hope you are aware, that the CV Joystick has 16 directions... 8 directions and their combinations...
like UP, UP-DIAG_RIGHT, DIAG_RIGHT, DIAG_RIGHT-RIGHT, RIGHT...
Games become very hard to steer if the "inbetweens" are not considered...
