I've been making slow and steady progress on Intellivision. Recent improvements inclide:
-Collision Detection
-Timing fixes
-Scrolling and Border effects
-Code optimization (back up to 60 fps)
many games should be in a nominally playable state now. Some will still have graphical glitches and ones requiring banking won't load, but I think I'll be able to start on that stuff soon.
Does anyone know how accurate Mesen truly is?
I've started work on this core. Fortunately, it was already in a pretty advanced state before I picked it up, so a lot of the complicated stuff was already done. So far I have controls and the basics of the sprites programmed in, but there is a very long way to go.
There is plenty of high level information about how the system works, so getting it into a usable state should be pretty easy.
Unfortunately I can't find any info about low level things like cycle timing, so for now this will be high level emulation only and lack the real hard core accuracy of NESHawk and AtariHawk.
Right now there is no sound or hit detection, but CPU emulation seems in order and the characters react to the controls, so that's about it for now. Stay tuned!
Update on VS System. Now all but one VS UniSystem games can be played! Contorls are are implemented in EmuHawk and can be used in TASing (although I'm not sure of the TASing potential of any particular game.)
The one notable exception is Hogan's Alley. The game boots and runs correctly, but light gun detection for that game is broken because the palette color appears to be slightly different then expected. I'm not sure if this is a problem of the emulated palette or a weakness in light gun detection emulation, but either way it doesn't work.
Dual System games also don't work, and it's not really obvious how they could be made to work, but maybe I'll work on it someday.
Alyosha, are there any runs that blew your mind?
In my opinion, and I think I can back it up sufficiently, a newcomer rec should first and foremost be newcomer-friendly. Which means they should look and sound good, have intuitive mechanics and the run itself should demonstrate easily discernible level of precision and planning without boring nor alienating the viewer. What is friendly for a pro isn't necessarily friendly for a newcomer. We already have stars for the pros.
