Well dont' get nervous, it's just a small problem and it only accures to very little of homebrews when i play them on the Intellivision using LTO Flash (99% are ok).
First John D's "Old School",
i'm sure this problem won't appear on a cratridge because i have a idea where it comes from and since the machine had to be shut off before you can play another game their wont' be nothing which can produce this.
however, if i run "Old School" (Old school High, Kid Robin Hood), the screen is garbled up and the sprites and background cards display something weird.
to sad in this way it's not playable, or no fun to play it, you can see what happens but erm...
decles whole StudiVision project shows something quite similar on the background, the playfield itself is clean.
here it's to see where it comes from (at least for the Studiovision, the problem of "Old School" could be caused by something else), you can define the characters used in the LTO Flash menu.
for StudioVision it's not a big problem, you can still play the games, it's really only the background which shows this problem.
but well it's a tiny bit sad.
what you can't see:
if you start any StudioVision game the screen will show a "faked" b&w "Mattel screen" (the palette), emulated all stripes appear,
played via LTO on the real harware only one of the stripes is left.
To say i expect it's not a problem of the LTO flash, i expect the games didn't proberly blank the graphical ram? (should i send out TRON to fix this? clearing the flags?).
It will be no problem if it's the sole game in a emulator or a sole game as a cartridge, there will be no remnants of a former program.
but maybe i'm wrong and someone has a solution for this.
decle can certainly update his stuff,
for "Old School" i'm not certain about.
also i'm not sure how far the once downloaded "Old School" is identical to the released cartridge.
these two are all problems that accured to me so far with the LTO Flash and homebrews.
...so far, i haven't tested all of them, "Old School" was randomly selected by me "let's see..." and StudioVision i certainly played.
which is damned to easy anyway and even easier on my slower PAL console.
while the concept of "Star Wars" i like, this sort of dogfight together with a docking sequence (move crosshair, correct velocity, imo the docking sequence should be no simple intermission scene) and buy this good - sell this good (e.g. king of the mountain, need so and so tons of hydrogene, food supply etc) can make a good game (do you remember "return to earth"?).
well you can't procedural generate planets and whole systems, or maybe... if the idea is reduced to the non graphical stuff.
a little of "star wars", a little of "lunar lander", a little of "King of the Mountain" and a little of "trollish comment generator" makes....
Elite for the Intellivision?
you can see that i have on my mothers TV the same "tearing in" issue, i still believe it's the VSYNC.
as i reported on my old tube TV i can fix this by screwing on the proper variable resistor until the tearing vanishes.
my mothers flatscreen i didn't like to open, also it seems more problematic to me to run and modify it because first i have to dismount the socket, but without a socket i can't put the TV upright to get on it's back and watch at the same time what happens on the screen.
well the good old days when a tv's back was covered with tared cardboard and fixed without a single screw...
yes it's dangerous this guy manipulates on the high voltage parts, blindfolded... (you have to watch the screen and fumble around in the guts of the tube, or use a mirror).
it was stated that a manual adjusting of the channel can help.
yes i know even this i know from the past, but as soon as the teraring vanishes the picture is bad and full of ghosts.
I have no idea what's the proper solution for a digital TV, except to open it and hope that there is still this vr to adjust VSYNC.
