Re: Tandy 64 Jr. - An intro for the PCJr.
Posted: Sat Mar 10, 2018 4:38 pm
So, I couldn't figure out why one machine was faster than the other one, but I was able to make the intro run flicker-free (or at least as flicker-free as I could... sometimes a little line appears at the bottom-left) in both machines.
Changes:
* Detects if machine is PCjr A (faster one) or B (regular one).
* Detects if runs in <128Kb: aborts
* Detects if runs on NEC v20 / emulator: aborts
* Detects if machine is not PCjr: aborts
* More stable raster bar, a tiny bit faster.
* Raster-bar covers the full scroll letters (before, a line was missing).
I would appreciate if someone can test it and tell if it runs without flicker.
Thanks!
