Alien Destroyer is another good example of an incorrect gif. The capture is not aligned with the attribute cells:

Re: Broken screenshots

Fixed both Pedro games mentioned, and also PedroVStrasidelnomZamku (minor bright difference). (I'm marking fixed titles on this thread by liking each post :D ) Also spotted problems with Quadrax (fixed). In this case original gif is scaled - notice the smoothed pixels specially on the top platforms:...

Re: Philips Videopac G7000 / Magnavox Odyssey 2 Programmer

Here's a comparison of both palettes with TMS9918 on the left and Vic-II (C64) on the right. https://i.postimg.cc/KkKWjTDS/palettes.png C64 tones are ugly and it wastes a few palette entries on grays. That's because they simply ran through voltage combinations (look at the alternating Y,Pb,Pr column...

Re: Philips Videopac G7000 / Magnavox Odyssey 2 Programmer

Colors are very consistent with the SG-1000 emulator video. As expected the CRT has a slightly lower gamma (darker midtones), making colours a bit more intense. But overall it compares well.

I agree that this palette is very good. Better than C64 on my opinion.

Re: Philips Videopac G7000 / Magnavox Odyssey 2 Programmer

The exact colours are hard to reproduce for these chips. Composite palettes are hard to handle, specially if you think about NTSC machines. Pre 1990s NTSC had a wider colourspace but TVs had "correction" circuits in order to compensate (see https://en.wikipedia.org/wiki/NTSC#SMPTE_C ) . Th...

That used the TMS9918 which was found in the MSX, TI99 and others. Used on ColecoVision, CreatiVision, Memotech MTX, MSX, SG-1000/SC-3000, Spectravideo, Sord M5, Tatung Einstein, Texas Instruments TI-99/4, Casio PV-2000 and Tomy Tutor.

Corrupted legacy gif. If you open it directly on Chrome, you get a 606x449 image!

Re: Are there any good games exclusive to the Timex Sinclair 2068/2048?

Are you going to check each page from www.timexsinclair.com to see if there's a corresponding page at SC? Already added a few titles using the Preservation Tools. It's more efficient that way I think. We can quickly check for existing titles and authors and add other details like price. No promises...
