Hi everyone! I have written a second game for the Creativision. I need someone to test it and also test the first game. Both games are universal 8-bit games written with CrossLib (https://github.com/Fabrizio-Caruso/CROSS-CHASE/). They are mass-compiled into 200 versions for nearly all 8-bit computer...

Thanks!

How are the 18k roms mapped in ram? How are 18k rom files structure?

I have figure this out and I have managed to implement some graphics in my game!

Hi everyone! I am developing Cross Chase for the Creativision with CC65. The game has no sound, yet, but when run under Mame it produces a horrible buzzing sound. Could someone test it for me and let me know if this issue is real or just a Mame artifact? Which other emulator could I use to test my g...

I have figure it out! Problem solved!

I may have figured out how to write onto VDP registers and memory: #define VDP_DATA 0xC000 #define VDP_WRITE 0xC002 #include <peekpoke.h> void VDP_REGISTER(unsigned char reg, unsigned char value) { POKE(VDP_DATA,value); POKE(VDP_WRITE,(reg|0x80)); } void VDP_POKE(unsigned short address, unsigned cha...

I may have figured out how to write into VDP registers and video ram. I am assuming that the two data and status/write registers are at $C000, $C002. Is this the case for Creativision? I now need to understand where color and character definitions are located in video ram. On the MSX, color definiti...

[SOLVED!] Hi I would like to understand how to write into video memory in order to redefine characters and set their colors in mode 1. I have done this already on the MSX in C (by using Z88DK): https://github.com/Fabrizio-Caruso/CROSS-CHASE/blob/master/src/cross_lib/display/init_graphics/z88dk/msx/m...

@Mobsie @Carlsson I understand I need to write into VDP memory and registers. Are registers just part of VDP memory and are they addressed in the same (indirect) way by writing data into VDP_Status_Write? MSX Basic has something as simple as VPOKE and VPEEK which let us write and read into video ram...
