    Something strange happened yesterday. So I have a bunch of different VGA cables. Including some thick ones. all have ferrite beads on both ends. Strangely enough I get the best results with the ones that come with the LCDs. The not so thick ones with blue VGA plugs and ferrite beads on both ends.


    Anyway, lately I thought my BenQ BL912 was showing a lot less ghosting VS my BenQ BL 702As. That was until yesterday when I found out the specific cable I was using for my BL 912 caused this. This cable is identical to the one I was using on my BL 702A. I have a bunch of these cables. But the one I am using for the BL 912 shows the least amount of ghosting.


    Anyway, for a short while yesterday the ghosting was completely gone when using this cable. On both monitors. Now the ghosting is back again. to the same level it was showing before. The other cables still makes it worse. Very strange. I don't understand why the ghosting was completely gone for a little while. As I was switching the cable between the monitors the regular ghosting was back. Very strange. Like the stars was aligned for a moment.


    At the same time I see the ghosting even if I use a VGA to HDMI converter plugged directly into the TC64 V2 (No VGA cable). But the fact that the ghosting was completely gone for a moment when using this random VGA cable makes me think there must be some kind of simple fix to this. It shows that the TC64 V2 can show a ghosting free picture for me. Something must have caused it.


    This was done in cartridge mode using 768x576@50Hz.

    OK, holding the menu button the monitor switches to a black screen and shows a 15kHz mode (which it can not display)

    yeah, you need a 15KHz compatible monitor for it to work. My BenQ BL702As and BL912 runs 15KHz just fine. You can also use 15KHz compatible CRT monitors or old CRT TVs. VGA to RGB/RGB scart should work just fine.


    (With my ports of MiST cores you can enable/disable the internal scandoubler by holding down the menu or F12 button for more than 1 second.)

    I just became aware of this quite recently. It's a very nice feature. Would love to have it for the TC64/TC64 V2 C64 core aswell. Aswell as 720x576 of course.

    i noticed the new c16 core uses 720x576 aswell. This resolution fills the screen and shows the correct aspect ratio for pal. This should really be an option for the c64 core. Aswell as the option to turn off the scandoubler

    Some interesting findings. First of all the left monitor (BenQ BL 912) shows substantial less ghosting VS the BL 702A (The one on the right). Not only that, but the TC64 V2 on the left (the one in cartridge mode) shows a tad less ghosting/smearing than the one on the right (the one in the docking station).


    If that was not enough, using it in the docking station makes it even worse. I can only guess it has to do with a cheap Chinese power supply or less groundplane when using it in the docking station VS using it in cartridge mode? I've tried all combinations here. Swapping TC64 V2s around, monitors and cables. That's how I know this.


    The setup on the left mostly shows a few ghost/smearing shadows for the white character. There are almost no visible ghosting/smearing trails for the blue and red character. However, the setup on the right has many ghosting/smearing trails for the white Karate dude but also very visible trails for the blue and red character. Monitors makes the biggest difference here, but docking station and the specific TC64 V2 also shows. Oh, and the TC64V2 on the right was an early one. Bought right after they were released. Not that I think something was changed component wise between the two TC64V2s. It's only a small difference.


    Certain games with certain colour combinations shows this more than others. This game (IK+) is one of those games that shows it clearly.


    I don't know why I haven't noticed this before, but there is a substantial difference between these two setups. I'm quite satisfied with the results I get from the BL912 setup here. Using 768x576@50Hz and VICII sync enabled. Which gives the best results for me. 640x480@50Hz is also good but will not show the whole vertical area in all games.


    It seems the TC64V2s are very picky with regards to monitors. will do more testing. The Lenovo q24i-10 monitor looks promising from pictures and information I saw over in the TC64 facebook group. Anyway, I'm quite surprised the BL912 shows noticeable less ghosting/smearing VS BL702A when used with the TC64V2s as I thought they were essentially the same based on how they behave on my Amigas, appart from 17 VS 19 inch sizes of course.


    There is no "power saving feature" - it's the output drive power settings that were reduced to the required minimum "per signal" for all cores, so nothing that can be seen or controlled from the Amiga-side. I've done that to reduce signal noise and improve metastbility. For some of the known-bad power supplies, it actually makes the PLL mod unnecessary.

    I see. I was probably thinking about the download description for the update and remembered something about lower power setting:


    • Indivision ECS Update file V1.15 (june 3rd, 2012) - pure update file, please flash with flash tool. This includes changes of V1.10, but uses lower power settings for the FPGA, which may improve performance with flaky power supplies.

    I have two Indivision ECS V1s. Same thing happens with me when I flash vv1.15. I assume v1.15 is a slightly modified v1.10 and that's why they didn't change the version number on the startup screen. I think they added some power saving feature in v1.15 VS 1.10. So very minor change.

    Here's a bootblock that I hope works better and fixes more titles.

    It shouldn't crash anymore, and it should also coerce the system a bit more into PAL.

    So this is an *.img file. Is it possible to write this to a floppy using ADF blitzer? I use ADF blitzer for writing ADFs to floppy.

    Not looked at this demo, but you could not miss the ghosting on the V2, no sign of it on the V1 or the ScanPlus

    Appreciate the tip regards copper tape, but the V1 copes fine without it.


    As there is no ghosting on the V1 I'll wait until the V2 patch board is available then decide which one has the better overall picture then sell the runner up.

    What Amiga are you using ECS V1/ECS V2 in?

    I managed to get an 'Indivision ECS V1' from eBay and the picture is far superior to the V2 on my setup.

    Its better than my 'ScanPlus ECS' in the interlaced modes and it works well with HighGfx.

    On the ECS v2 the ghosting was so bad I could read the text in the ghosted image, ECS v1 no such issue.

    I'll probably hang on to the v2 to see what that's like once the patch board is available.

    Did you try Andromedas DOS demo on your Indivision ECS V1? I still get a little bit of ghosting on my V1s. But when they are in my A600s with the VGA connector secured to the RF shield it's barely noticeable. In my A500s it's quite noticeable.


    For my ECS V2 I now get a crystal clear and sharp picture with the latest profile I made. You can find my profile in post #175 with a download. I also added copper tape to the VGA cable. There is still visible ghosting, especially in DOS demo, where it's very visible. But in general I don't see that much ghosting outside of examples like DOS demo or stuff that has certain colour combinations. And the picture I get on my BenQ BL702A and BL912 monitors with this profile is actually sharper than I get from ECS V1. It's crystal clear, sharp and shows perfect patterns with no artifacts. So appart from the ghosting which can be seen in certain scenarios, the picture is extremely good with this profile.


    Oh, and I'm using the latest firmware for ECS V2

    You'll have to mount the image and load it in BASIC just like you would do on a real C64. For most original games that means typing LOAD"*",8,1 and press return. For most games you'll also have to make sure no other hardware expansions are enabled, and only one disk drive.

    Thanks. I had already tried that but didn't wait long enough for the game to load. I simply assumed something was wrong. I sometimes forget how slow a 1541 can be :)


    Thanks again, will go and try out some G64s

    I downloaded a big library of G64 games. When I open the G64 files I get a PRG file inside it. Pressing return on the PRG file does nothing on any of the G64 images I've tried thus far.


    Anything I'm missing here? I tried to look in the 9M version of TC64V1/V2 manual but couldn't find any info regarding how to run these types of images.

    No not so easy as the VIC 20 core doesn't have a menu system like the C64 main core has. So most of the settings are set static during the compilation of the core and can't be changed by software.

    Thanks for the answer. Not a big deal as 800x600@72Hz is 'good enough' for VIC20 use
