I must admit i can not help a lot here , i hate GUI making and sound programming is not cup of tea =(

Thanks for the reply, that will be usefull. That's a shame there is no real tracker but i'll do with this

Thanks a lot ! Yep , i am using sjasm as assembler. A little question , is there a SN76489A player and format adapted for colecovision (small RAM/ROM footprint) as VGM format and players for SMS seems a bit big ?

Thanks a lot for replies, i finaly found what i was searching in the coding guide =) Thanks for pointing bluemsx as it is great. Still have a lot of question but i'm going to read doc first

Hi all, I would to make a try with colecovision programming.I am sorry if someone already asked for this but i didn't found replies or only partial replies :/ I notice in a lot of examples, programmer attacks VDP/SN via Bios functions.Is there a complete documentation about where and how are mapped VDP/SN/joystick ports and some disassembly of some bios functions like writing/reading VDP/VRAM ? About NMI on Vblank , i was wondering what does it do except jumping at your custom NMI handler (does it alter registers , VDP , stack ? Again , is there some disassembly listing of this handler ? To finish , is there a good emulator for testing on colecovision (with a lot of chance , with an intergrated debugger ?) Again , sorry if questions have already asked, just please point me on theses , i'll remove the topic. Thx
