Yeah, I use Magellan quit a bit.
20x12 is one piece of the puzzle. But 12 tiles takes up the same room as 24. So I imagine, these pixels are twice as high as the TI as they take up the same real estate on the screen.
However, output from magellan gives us data statements and character definitions etc.
I have been tinkering with the TI since 1981-82 and can look at a binary string and convert it to hex without doing the math, just from repetitive use. Though, that is fading a little with these tools doing the work!
The output for IntyBasic is more like:
TI would be Call Char(65,"F00FFF00FF")
Hchar(1,1,65) :: Hchar(1,2,66)... would be something like DATA $8000, $8001 ......
Then we have backtab color settings etc.
This type of tool would speed the process incredibly, as it does for the TI. I made the Pacman maze and 4 ms. Pacman mazes in about 45 minutes. When I did Mirror Maze.
That would have taken me a week on graph paper OR until I gave up... plus you really get to SEE what it will look like. I could tweak a wall definition and see the impact across the entire maze... An AWESOME tool.
If this was 1981, it would be thrilled just to have an Intellivision Basic. But I must admit, I am spoiled now. I don't want to do busy work. I want to play around with a game screen, then write the game that uses it.
One thing I may have missed, is it possible to output DISPLAY AT commands with a width of 32 for Mode 2? It gives an option, but I cannot make it work.
I use the 28 wide and fill in the remaining 4 columns if I need too. Most of the time, I don't.
