TI-81 asm invaders
« on: September 03, 2020, 07:42:43 am »
Hello all

I almost cried while being able to run native code on my old dust gathering TI81, with Unity !
Benjamin Moody did a great work.

The idea of using character strings already stored in the ROM for a hangman game : awesome
The luxury of having the loader pointing you directly to a typo in the code editor : awesome too

Though, there are unfortunately not much programs to run. I typed in "Space Invaders", but unfortunately it doesn't work as expected. When I run it, nothing happens. Then, after waiting a while (or pushing CLEAR), I see the game-over screen with "Your score is 0"

Was anyone able to run it ?
I don't know who's the author of invaders, if it's also banjamin moody or someone else.

I believe it might have to do with the fact that my ROM version is 2.0V, which is known for having to expressly refresh the LCD. Should a ROM_CALL DispHL be added in the game for it to work on 2.0V ?

Thanks.
