oh my god!! you're an incredible source of ideas and games! :D :D :D :D

but i would be truly happy if you could complete one game and make it fully playable. c'mon mobsie, make us a christmas gift and produce the first 100% playable homebrew game for creativision! ;)

ps. the "pit" is very large: 20 blocks as opposed to the "standard" 10.

do you think it would be possible to fit 2 "standard" pits in the screen, as opposed to 1 single "large" one?

yes, we have later a two player mode at the same time. Then with 2 smaller "pit". BUT i have some hidden ideas and need the big one.
Yes i know, normal better to finish one game and then start the next.
This i will do later, at the moment after i write some stuff that drive me "brain deed" like the scroll stuff in the scramble demo (from VDP Ram to VDP RAM etc.) i need some easy thinks. And better make some easy stuff but no pause :D

Nice! I agree that Tetris should not be wider than 10 columns, unless you are making a special variant of the game that somehow will remain playable even with different properties.

I suppose one of the bigger hurdles is where to store logical data for games, as it is cumbersome to read the VDP. At least that is what I keep returning to thinking about for future Creativision games. The onboard 1K is plenty compared to Atari 2600, TI-99/4A or Colecovision but still rather little amount of memory even compared to the VIC-20 that I'm used with.

i try to develop my idea, when it take to much time i will close the idea and make the standard version.
RAM for me is no problem, on the TI-99/4a we have only 256kb. They guy who made the scramble game for the TI was able to handle with this 256kb.
In my demos ( i don`t call it games ) i store the sprite table, all game vars. etc in the free RAM and have still a lot free.

In the Shamus for example i hold the sprite-table, the array for the shoot, the arrays for the enemies atc. all in the RAM.

On the TI-99 he use the 32kb RAM expansion for the Scramble MAP data because the TI is really slow also in ASS.

I store the compresed part of the map i use actual in one part of the VDP, from here i decompress 1/3 screen in one frame to the of screen vdp name table.
Then after 3 frames the name table will be switch to the new one.

This all in the VBI, and here also still a lot time free.
